See Issue #5881: setUrl was inherited from ol.source UrlTile, which creates a wrong tileUrlFunction: The official WMTS URL Template variables were no longer replaced.
Use the defined source projection despite it being equivalent to the rendering projection to enable using the specified alias code name instead of the code provided by the renderer's projection object. For example: The server only knows the name "EPSG:900913", which is an alias for the equivalent "EPSG:3857", that the renderer uses (by default).
This adds the pixelTolerance option parameter to the constructor of ol.interaction.Extent.
In this way the user can override the current default value of 10.
Also IMHO it doesn't make much sense to have issues of previous patch releases eg. 4.3.4 in here as these have their own release notes already, but I'll leave that for your debate
Previously, events weren't being propagated if the active draw
interaction had its `freehand` property set to true. This means that
you can't use your mouse wheel to zoom the map in freehand mode.
This change sets the default `pass` value to true and adds additional
logic to determine when it should be set to false (and stop event
propagation).
This commit also changes the TextReplay.drawText() signature, and moves
geometry calculation into drawText(). This improves performance where no
text needs to be rendered (TextStyle.getText() == ''), which is used often
in applications.
Having the coverage calculation code in the test files makes it hard to debug
tests, so it is better to only analyze coverage on Travis, and not locally.
There is a great deal of lines about Greenkeeper merges in the changelog, making it
hard to find real changes to the code.
This commit modifies the changelog task to exclude such lines.
This adds a unit test that tests weather the projection (spatial reference)
is being added inside the geometry object when writing features as
esriJson.
The WFS transaction failed if the srsDimension was not present on the
geometries.
Unit tests have been changed to accomodate the srsDimension attribute.
Contrary to Mapserver, Geoserver sets the srsDimension attribute on
the child of the geometry node, not on the points list.
This fix searches that node as well.
A small unit test was also added.
Changes to the layer were only propagated in some cases like addition/removal of a
layer to the group.
To make it consistent both with the rest of the group.js file and with the
layer.js file, the changes are now always notified.
Appears to have just been a typeo, using the minLon_, maxLon_ member variables rather than the function parameters provided.
This was creating very wide lines of parallel which were sometimes very slow in Chrome.
Until now, the features of transparent vector layers were rendered using
the layer opacity. This caused colors to mix together and the opacities
to stack up to an higher value than the expected layer opacity.
With this commit, the features are rendered at 100% opacity to an
intermediate canvas which ensures colors do not mix up even in the case
of features using an array of styles. The intermediate canvas is then
composed to the map canvas using the layer opacity.
Transparent layers are automatically detected, non-transparent layers
are not affected by the change.
As mentioned on issue 6992, EsriFormat was adding the spatial reference
outside the geometry, failing to insert data via the Arcgis rest API.
The spatial reference should be inside the geometry.
OriginalEvent 'mousemove' break default OL interaction move of map canvas. Using OL event 'pointermove' have same function and allow move of map canvas.
The previous x coordinate was one earth to the left which led to confusing results with everything.
This change makes sure the map is centered in a proper location (pretty much the same as before) WITHIN proper bounds.
This method does have value for users that want to switch between ol.Feature
and ol.render.Feature and still be able to use #getGeometry().getType() in a
style function to determine the feature geometry's type.
Some WFS servers like tinyOWS require the feature prefix to be in the
feature type for the feature to be found (eg `prefix:layer`).
The problem was, the prefix was always added to the feature type which
gave us a type name like `prefix:prefix:feature` or
`feature:prefix:feature`. The requests were then rejected by the WFS
server.
We now check if the feature type starts with the prefix. If it does, we
don't append it again. If it doesn't we do.
The code used to rely on the dimension. However, the dimension can only
be read from a GML3 document. This caused, for 3D geometries:
- An assertion error to be raised since the flatCoordinates list
contains more than 3 elements: "Assertion failed: flatCoordinates should
have a length of 3" The value of flatCoordinates for a 3D point was
something like `[2586394, 1232407, 0, 731, NaN, 0]`
- The value of the Z coordinates to be incorrect and always set to 0
This patch simplifies and correct the parsing of the coordinates:
- Don't parse groups of coords and the coordonates at the same time.
- Detect the dimension for the coordinates.
- If the Z coordinate exists, its value is used, otherwise, we use 0.
- Correct the presentation of test data to make it work with the new
parser.
- Add a test for a 3D point.
This enhance the procedure to find path of jsdoc binary by checking if the file exists.
It also use 2 possible paths to perform this check, one for npm and the other for yarn.
Close#6633
Previous typing was confusing the compiler. It could not figure out the
difference between the proj4 property and the constructor, which lead to
errors such as:

- Add a version property to olx.format.WFSWriteTransactionOptions to set
the WFS protocol version to use
- Use the specified version to use the correct schema and version in the
GML request
- Use the version to select the proper GML serializer
Make the overlay visible before updating the render position
so that the `offsetWidth` and `offsetHeight` can be
considered in evaluating the offset and positioning of the
element

For better drawing experience, two changes were made to the behavior of the Draw interaction:
1. On long press, the current vertex can be dragged to its desired position.
2. On touch move (e.g. when panning the map on a mobile device), no draw cursor is shown, and the geometry being drawn is not updated. But because of 1., the draw cursor will appear on long press. Mouse moves are not affected by this change.
#### Changes in proj4 integration
Because relying on a globally available proj4 is not practical with ES modules, we have made a change to the way we integrate proj4:
* The `setProj4()` function from the `ol/proj` module was removed.
* A new `ol/proj/proj4` module with a `register()` function was added. Regardless of whether the application imports `proj4` or uses a global `proj4`, this function needs to be called with the proj4 instance as argument whenever projection definitions were added to proj4's registry with (`proj4.defs`).
It is also recommended to no longer use a global `proj4`. Instead,
npm install proj4
and import it:
```js
importproj4from'proj4';
```
Applications can be updated by importing the `register` function from the `ol/proj/proj4` module
```js
import{register}from'ol/proj/proj4'
```
and calling it before using projections, and any time the proj4 registry was changed by `proj4.defs()` calls:
```js
register(proj4);
```
#### Removal of logos
The map and sources no longer accept a `logo` option. Instead, if you wish to append a logo to your map, add the desired markup directly in your HTML. In addition, you can use the `attributions` property of a source to display arbitrary markup per-source with the attribution control.
#### Replacement of `ol/Sphere` constructor with `ol/sphere` functions
The `ol/Sphere` constructor has been removed. If you were using the `getGeodesicArea` method, use the `getArea` function instead. If you were using the `haversineDistance` method, use the `getDistance` function instead.
The following methods did get the optional this (i.e. opt_this) arguments removed. Please use closures, the es6 arrow function or the bind method to achieve this effect (Bind is explained here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
#### Renamed `exceedLength` option of `ol.style.Text` to `overflow`
To update your applications, simply replace `exceedLength` with `overflow`.
#### Deprecation of `ol.source.ImageVector`
Rendering vector sources as image is now directly supported by `ol.layer.Vector` with the new `renderMode: 'image'` configuration option. Change code like this:
```js
newol.layer.Image({
source:newol.source.ImageVector({
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
})
});
```
to:
```js
newol.layer.Vector({
renderMode:'image',
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
});
```
### v4.5.0
#### Removed GeoJSON crs workaround for GeoServer
Previous version of GeoServer returned invalid crs in GeoJSON output. The workaround in `ol.format.GeoJSON` used to read this crs code is now removed.
#### Deprecation of `ol.Attribution`
`ol.Attribution` is deprecated and will be removed in the next major version. Instead, you can construct a source with a string attribution or an array of strings. For dynamic attributions, you can provide a function that gets called with the current frame state.
Before:
```js
varsource=newol.source.XYZ({
attributions:[
newol.Attribution({html:'some attribution'})
]
});
```
After:
```js
varsource=newol.source.XYZ({
attributions:'some attribution'
});
```
In addition to passing a string or an array of strings for the `attributions` option, you can also pass a function that will get called with the current frame state.
```js
varsource=newol.source.XYZ({
attributions:function(frameState){
// inspect the frame state and return attributions
return'some attribution';// or ['multiple', 'attributions'] or null
}
});
```
### v4.4.0
#### Behavior change for polygon labels
Polygon labels are now only rendered when the label does not exceed the polygon at the label position. To get the old behavior, configure your `ol.style.Text` with `exceedLength: true`.
#### Minor change for custom `tileLoadFunction` with `ol.source.VectorTile`
It is no longer necessary to set the projection on the tile. Instead, the `readFeatures` method must be called with the tile's extent as `extent` option and the view's projection as `featureProjection`.
Before:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data));
tile.setProjection(format.readProjection(data));
// uncomment the line below for ol.format.MVT only
//tile.setExtent(format.getLastExtent());
});
```
After:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data,{
featureProjection:map.getView().getProjection(),
// uncomment the line below for ol.format.MVT only
//extent: tile.getExtent()
}));
);
```
#### Deprecation of `ol.DeviceOrientation`
`ol.DeviceOrientation` is deprecated and will be removed in the next major version.
The device-orientation example has been updated to use the (gyronorm.js)[https://github.com/dorukeker/gyronorm.js] library.
### v4.3.0
#### `ol.source.VectorTile` no longer requires a `tileGrid` option
By default, the `ol.source.VectorTile` constructor creates an XYZ tile grid (in Web Mercator) for 512 pixel tiles and assumes a max zoom level of 22. If you were creating a vector tile source with an explicit `tileGrid` option, you can now remove this.
If you need to change the max zoom level, you can pass the source a `maxZoom` option. If you need to change the tile size, you can pass the source a `tileSize` option. If you need a completely custom tile grid, you can still pass the source a `tileGrid` option.
#### `ol.interaction.Modify` deletes with `alt` key only
To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex. If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option. For example, to allow deletion on a single click with no modifier keys, configure the interaction like this:
The motivation for this change is to make the modify, draw, and snap interactions all work well together. Previously, the use of these interactions with the default configuration would make it so you couldn't reliably add new vertices (click with no modifier) and delete existing vertices (click with no modifier).
#### `ol.source.VectorTile` no longer has a `tilePixelRatio` option
The `tilePixelRatio` option was only used for tiles in projections with `tile-pixels` as units. For tiles read with `ol.format.MVT` and the default tile loader, or tiles with the default pixel size of 4096 pixels, no changes are necessary. For the very rare cases that do not fall under these categories, a custom `tileLoadFunction` now needs to be configured on the `ol.source.VectorTile`. In addition to calling `tile.setFeatures()` and `tile.setProjection()`, it also needs to contain code like the following:
#### `ol.animate` now takes the shortest arc for rotation animation
Usually rotation animations should animate along the shortest arc. There are rare occasions where a spinning animation effect is desired. So if you previously had something like
```js
map.getView().animate({
rotation:2*Math.PI,
duration:2000
});
```
we recommend to split the animation into two parts and use different easing functions. The code below results in the same effect as the snippet above did with previous versions:
```js
map.getView().animate({
rotation:Math.PI,
easing:ol.easing.easeIn
},{
rotation:2*Math.PI,
easing:ol.easing.easeOut
});
```
### v4.2.0
#### Return values of two `ol.style.RegularShape` getters have changed
To provide a more consistent behaviour the following getters now return the same value that was given to constructor:
`ol.style.RegularShape#getPoints` does not return the double amount of points anymore if a radius2 is set.
`ol.style.RegularShape#getRadius2` will return `undefined` if no radius2 is set.
### v4.1.0
#### Adding duplicate layers to a map throws
Previously, you could do this:
```js
map.addLayer(layer);
map.addLayer(layer);
```
However, after adding a duplicate layer, things failed if you tried to remove that layer.
Now, `map.addLayer()` throws if you try adding a layer that has already been added to the map.
#### Simpler `constrainResolution` configuration
The `constrainResolution` configuration for `ol.interaction.PinchZoom` and `ol.interaction.MouseWheelZoom`
can now be set directly with an option in `ol.interaction.defaults`:
The v4.1.0 release includes features and fixes from 91 pull requests.
#### Interactive overview map
The extent rectangle on the overview map can now be dragged to control the view for the main map.
#### Setting min and max zoom for a view
You can now change the min or max zoom for a view after it has been created. This can be useful if you want to limit how far out users can zoom based on changes in viewport width (use `view.setMinZoom()` for this).
#### Adding duplicate layers to a map throws
Previously, you could do this:
```js
map.addLayer(layer);
map.addLayer(layer);
```
However, after adding a duplicate layer, things failed if you tried to remove that layer.
Now, `map.addLayer()` throws if you try adding a layer that has already been added to the map.
#### Simpler `constrainResolution` configuration
The `constrainResolution` configuration for `ol.interaction.PinchZoom` and `ol.interaction.MouseWheelZoom`
can now be set directly with an option in `ol.interaction.defaults`:
```js
ol.interaction.defaults({
constrainResolution:true
});
```

This is a patch release to fix several minor issues and two regressions in the [4.1.0 release](https://github.com/openlayers/openlayers/releases/tag/v4.1.0).
## Changes
* [#6711](https://github.com/openlayers/openlayers/pull/6711) - Correct path to cleancss ([@tschaub](https://github.com/tschaub))
The v4.2.0 release includes features and fixes from 87 pull requests.
#### New `movestart` event on `ol.Map`
The map now has a `movestart` event, as countarpart to the already existing `moveend` event.
#### New `moveTolerance` option in `ol.Map`
Some touch devices do not play well with OpenLayers's way of detecting clicks. To overcome this, a new `moveTolerance` option was introduced, so users can override the 1 pixel threshold above which a touch-release sequence won't be considered a click any more.
#### Support for multiple layers in `ol.format.TopoJSON`
With the new `layerName` and `layers` options, applications can extract the layer as additional attribute for vector features from `ol.format.TopoJSON`. This can especially be useful for styling vector tile layers.
#### New `tileJSON` option for `ol.source.TileJSON`
Like `ol.source.TileUTFGrid`, `ol.source.TileJSON` now also has a `tileJSON` option to configue it with inline TileJSON instead of a TileJSON URL.
#### New `ol.format.filter.during` filter
Although OpenLayers has no support for WFS v2.0, we added `ol.format.filter.during` for the `During` temporal operator.
#### Improved vector tile rendering at non-native resolutions
The vector tile renderer now uses an internal tile grid for all resolutions to cache pre-rendered tiles, even if the tile source does not have tiles for the viewed resolution. This improves rendering quality and performance.
#### New `insertVertexCondition` for `ol.interaction.Modify`
Applications can now control whether a vertex will be inserted into the modified geometry. This makes it easier to modify custom geometries.
#### New `callback` option for `ol.View#fit()`
To allow applications to perform custom actions when an animation associated with `ol.View#fit()` is completed, that method now has a new `callback` option.
#### New `ol.View#getInteracting()` getter
Like `ol.View#getAnimating()` returns `true` during a view animation, `ol.View#getInteracting()` returns `true` while users are interacting with the view.
#### New `hasZ` option for `ol.format.WFS#writeTransaction()`
When the new `hasZ` option is set to `true`, 3D coordinates will be preserved and encoded when writing a WFS transaction.
#### New `wrapX` option for `ol.source.Stamen`
Like other tile sources, `ol.source.Stamen` now also has a `wrapX` option, which allows applications to turn off wrapping the world in x direction.
#### Label support for `ol.Graticule`
The `ol.Graticule` component has several new options to add and control the output of labels. To turn on labelling, configure `ol.Graticule` with `showLabels: true`. The new options to control label formatting are `lonLabelFormatter`, `latLabelFormatter`, `lonLabelPosition` and `latLabelPosition`.
#### Return values of two `ol.style.RegularShape` getters have changed
To provide a more consistent behaviour the following getters now return the same value that was given to constructor:
`ol.style.RegularShape#getPoints` does not return the double amount of points anymore if a radius2 is set.
`ol.style.RegularShape#getRadius2` will return `undefined` if no radius2 is set.

The new `ol.Sphere.getArea()` and `ol.Sphere.getLength()` methods can be used to calculate spherical measures on geometries. This is the recommended over using the `geometry.getArea()` or `geometry.getLength()` methods.
Bad:
```js
geometry.getArea();
```
Good:
```js
ol.Sphere.getArea(geometry);
```
#### `ol.interaction.DragAndDrop` can be configured with a vector source
It is now possible to configure the drag and drop interaction with a vector source:
With this configuration, all features on the source are eligible for modification while the interaction is active.
#### `ol.interaction.Modify` deletes with `alt` key only
To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex. If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option. For example, to allow deletion on a single click with no modifier keys, configure the interaction like this:
The motivation for this change is to make the modify, draw, and snap interactions all work well together. Previously, the use of these interactions with the default configuration would make it so you couldn't reliably add new vertices (click with no modifier) and delete existing vertices (click with no modifier).
#### `ol.source.VectorTile` no longer requires a `tileGrid` option
By default, the `ol.source.VectorTile` constructor creates an XYZ tile grid (in Web Mercator) for 512 pixel tiles and assumes a max zoom level of 22. If you were creating a vector tile source with an explicit `tileGrid` option, you can now remove this.
If you need to change the max zoom level, you can pass the source a `maxZoom` option. If you need to change the tile size, you can pass the source a `tileSize` option. If you need a completely custom tile grid, you can still pass the source a `tileGrid` option.
#### `ol.source.VectorTile` no longer has a `tilePixelRatio` option
The `tilePixelRatio` option was only used for tiles in projections with `tile-pixels` as units. For tiles read with `ol.format.MVT` and the default tile loader, or tiles with the default pixel size of 4096 pixels, no changes are necessary. For the very rare cases that do not fall under these categories, a custom `tileLoadFunction` now needs to be configured on the `ol.source.VectorTile`. In addition to calling `tile.setFeatures()` and `tile.setProjection()`, it also needs to contain code like the following:
#### `ol.animate` now takes the shortest arc for rotation animation
Usually rotation animations should animate along the shortest arc. There are rare occasions where a spinning animation effect is desired. So if you previously had something like
```js
map.getView().animate({
rotation:2*Math.PI,
duration:2000
});
```
we recommend to split the animation into two parts and use different easing functions. The code below results in the same effect as the snippet above did with previous versions:
```js
map.getView().animate({
rotation:Math.PI,
easing:ol.easing.easeIn
},{
rotation:2*Math.PI,
easing:ol.easing.easeOut
});
```

The 4.4.0 release includes features and fixes from 80 pull requests, including first time contributions from @EduardoNogueira, @ath0mas, @f7o, @trevorblades, @viethang, and @wb14123. There are some really nice rendering enhancements included in this release. It is now possible to render labels along lines (see [#7239](https://github.com/openlayers/openlayers/pull/7239) for more detail) and polygon labels are only rendered if they fit within the polygon ([#7292](https://github.com/openlayers/openlayers/pull/7292)). In addition, we now render tiles with an opacity transition, so tiled layers more gracefully fade in ([#7267](https://github.com/openlayers/openlayers/pull/7267)).
### Upgrade notes
#### Behavior change for polygon labels
Polygon labels are now only rendered when the label does not exceed the polygon at the label position. To get the old behavior, configure your `ol.style.Text` with `exceedLength: true`.
#### Minor change for custom `tileLoadFunction` with `ol.source.VectorTile`
It is no longer necessary to set the projection on the tile. Instead, the `readFeatures` method must be called with the tile's extent as `extent` option and the view's projection as `featureProjection`.
Before:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data));
tile.setProjection(format.readProjection(data));
// uncomment the line below for ol.format.MVT only
//tile.setExtent(format.getLastExtent());
});
```
After:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data,{
featureProjection:map.getView().getProjection(),
// uncomment the line below for ol.format.MVT only
//extent: tile.getExtent()
}));
);
```
#### Deprecation of `ol.DeviceOrientation`
`ol.DeviceOrientation` is deprecated and will be removed in the next major version.
The device-orientation example has been updated to use the (gyronorm.js)[https://github.com/dorukeker/gyronorm.js] library.

The 4.5 release includes enhancements and fixes from 50 or so pull requests. Headlining this release, vector layers got a new `declutter` option that can be used to avoid overlapping labels. See the [street labels example](http://openlayers.org/en/latest/examples/street-labels.html) for a demonstration of this feature.
Please note that if you are using `closure-util` to build your OpenLayers based application, it is time to migrate to using the [`ol` package](https://www.npmjs.com/package/ol) and a module bundler like webpack. OpenLayers has not had a dependency on the Closure Library since the [3.19 release](https://github.com/openlayers/openlayers/releases/tag/v3.19.0); and with the 5.0 release we will be moving completely away from `goog.require` and `goog.provide`, dropping support for `closure-util`, and going with ES modules for our sources.
We will be adding details to the wiki about upcoming changes in 5.0 and tips on how to upgrade. We'll likely have a few more 4.x releases before the 5.0 release. But if you're interested in continuing to get feature enhancements in future releases, migrating to the `ol` package now will make the transition easier.
### Upgrade notes
#### Removed GeoJSON crs workaround for GeoServer
Previous version of GeoServer returned invalid crs in GeoJSON output. The workaround in `ol.format.GeoJSON` used to read this crs code is now removed.
#### Deprecation of `ol.Attribution`
`ol.Attribution` is deprecated and will be removed in the next major version. Instead, you can construct a source with a string attribution or an array of strings. For dynamic attributions, you can provide a function that gets called with the current frame state.
Before:
```js
varsource=newol.source.XYZ({
attributions:[
newol.Attribution({html:'some attribution'})
]
});
```
After:
```js
varsource=newol.source.XYZ({
attributions:'some attribution'
});
```
In addition to passing a string or an array of strings for the `attributions` option, you can also pass a function that will get called with the current frame state.
```js
varsource=newol.source.XYZ({
attributions:function(frameState){
// inspect the frame state and return attributions
return'some attribution';// or ['multiple', 'attributions'] or null
}
});
```

The 4.6 release includes enhancements and fixes from 30 or so pull requests. Headlining this release, vector layers got new `textBackgroundFill`, `textBackgroundStroke` and `padding` options that can be used to render background boxes for text. `ol.source.ImageVector` is now deprecated and replaced by a more convenient way to render vectors as images: by simply setting `renderMode: 'image'` on the vector layer.
Please note that if you are using `closure-util` to build your OpenLayers based application, it is time to migrate to using the [`ol` package](https://www.npmjs.com/package/ol) and a module bundler like webpack. OpenLayers has not had a dependency on the Closure Library since the [3.19 release](https://github.com/openlayers/openlayers/releases/tag/v3.19.0); and with the 5.0 release we will be moving completely away from `goog.require` and `goog.provide`, dropping support for `closure-util`, and going with ES modules for our sources.
See the [wiki](https://github.com/openlayers/openlayers/wiki/OpenLayers-v5.x) about upcoming changes in 5.0 and tips on how to upgrade. We likely won't have another 4.x release before the 5.0 release. If you're interested in continuing to get feature enhancements in future releases, migrating to the `ol` package now will make the transition easier.
### Upgrade notes
#### Renamed `exceedLength` option of `ol.style.Text` to `overflow`
To update your applications, simply replace `exceedLength` with `overflow`.
#### Deprecation of `ol.source.ImageVector`
Rendering vector sources as image is now directly supported by `ol.layer.Vector` with the new `renderMode: 'image'` configuration option. Change code like this:
```js
newol.layer.Image({
source:newol.source.ImageVector({
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
})
});
```
to:
```js
newol.layer.Vector({
renderMode:'image',
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
});
```

This tutorial serves as a suggested project setup using NPM and Browserify for the most basic needs. There are several other options, and in particular you might be interested in a more modern one (ES2015) [using Webpack with OpenLayers](https://gist.github.com/tschaub/79025aef325cd2837364400a105405b8).
## Initial steps
Create a new empty directory for your project and navigate to it by running
`mkdir new-project && cd new-project`. Initialize your project using `npm init`
and answer the questions asked.
Create a new empty directory for your project and navigate to it by running`mkdir new-project && cd new-project`. Initialize your project using `npm init` and answer the questions asked.
At this point you can ask NPM to add required dependencies by running
`npm install --save-dev openlayers browserify watchify uglify-js`. Watchify and
Uglify will be used to monitor for changes and to build into a minified
bundle.
Add OpenLayers as dependency to your application with `npm install --save ol`.
At this point you can ask NPM to add required development dependencies by running
We will be using `cssify` to include the css definitions required by OpenLayers in our bundle. `watchify`, `http-server` and `uglify-js` are used to monitor for changes and to build into a minified bundle. `babelify` and `babel-plugin-transform-es2015-modules-commonjs` are used to make the `ol` package, which was created using ES2015 modules, work with CommonJS.
## Application code and index.html
Place your application code in `index.js`. Here is a simple starting point:
With simple scripts you can introduce the commands `npm run build` and `npm start` to
manually build your bundle and watch for changes, respectively. Add the following
to the script section in `package.json`:
With simple scripts you can introduce the commands `npm run build` and `npm start` to manually build your bundle and watch for changes, respectively. Add the following to the script section in `package.json`:
Now to test your application open http://localhost:8080/ in your browser. `watchify` will update `bundle.js` whenever you change something. You simply need to reload the page in your browser to see the changes.
```
$ npm start
```
Note that `bundle.js` will contain your application code and all dependencies
used in your application, in this case the official full build of OpenLayers.
If you only need parts of OpenLayers you can create
[custom builds](../../builder).
Note that `bundle.js` will contain your application code and all dependencies used in your application. From OpenLayers, it only contains the required components.
**Note**: When building an application with dependencies that are available as [npm](https://npmjs.com/) packages, it will probably be easier to use the [ol](https://npmjs.com/package/ol) package and follow the instructions there.
The OpenLayers code uses the Closure Library, and it is compiled with the
Closure Compiler. Using OpenLayers in an application does not require using
Closure. But using Closure in an OpenLayers application is possible. And this
is what this tutorial is about.
When you want to include OpenLayers as separate script without bundling with your application, follow the [Creating custom builds](./custom-builds.html) tutorial instead.
This tutorial will teach you how to set up an OpenLayers application based on
the [`closure-util`](https://github.com/openlayers/closure-util) node package,
which provides utilities for working with Closure. Using `closure-util` is one

functions calculate spherical lengths and areas for geometries. Lengths are
calculated by assuming great circle segments between geometry coordinates.
Areas are calculated as if edges of polygons were great circle segments.</p>
<p>Note that the <code>geometry.getLength()</code> and <code>geometry.getArea()</code>
methods return measures of projected (planar) geometries. These can be very
different than on-the-ground measures in certain situations — in northern
and southern latitudes using Web Mercator for example. For better results,
