-OpenLayers makes it easy to put a dynamic map in any web page. It can -display map tiles and markers loaded from any source. MetaCarta developed the initial version of -OpenLayers and gave it to the public to further the use of geographic -information of all kinds. OpenLayers is -completely free, Open Source JavaScript, released under the BSD License.
- -We've released a Map Viewer Service that lets you put a map in your page easily. Just put this HTML in your page:
-- <iframe src="http://openlayers.org/viewer/" - width="400px" height="200px" - scrolling="no" - marginwidth="0" marginheight="0" - frameborder="0"> - </iframe>- -
Read more examples in the 20-second tutorial. The visual appearance of the MapViewer is not yet stable. If you like it, please join the users' email list and tell us about your use.
- -OpenLayers is a pure JavaScript library for displaying map data in most -modern web browsers, with no server-side dependencies. OpenLayers implements a -(still-developing) JavaScript -API for building rich web-based geographic applications, similar to the -Google Maps and MSN Virtual Earth APIs, with one important difference -- -OpenLayers is Free Software, developed for and by the Open Source software -community.
- -Furthermore, OpenLayers implements industry-standard methods for geographic -data access, such as the OpenGIS Consortium's Web Mapping Service (WMS) and Web -Feature Service (WFS) protocols. Under the hood, OpenLayers is written in -object-oriented JavaScript, using Prototype.js and components from the Rico library. The OpenLayers code base already has -hundreds of unit tests, via the Test.AnotherWay -framework.
- -As a framework, OpenLayers is intended to separate map tools from map -data so that all the tools can operate on all the data sources. This -separation breaks the proprietary silos that earlier GIS revolutions have -taught civilization to avoid. The mapping revolution on the public Web should -benefit from the experience of history.
- -Releases are made available on the downloads page. -Additionally, if you wish to use OpenLayers in a web application, you can -include - - http://www.openlayers.org/api/OpenLayers.js - in your page, to always get the latest release.
- -The code is also available in our -Subversion repository. -Using Subversion, you can keep up to the absolute bleeding edge of the code. -If you wish to report a bug in the API, and you are able to use Subversion, -please see if the bug has been fixed in Subversion first: OpenLayers is -under rapid development, so things change quickly. -
- -If you don't have Subversion or don't want to download the code, you can -still try some live examples on -openlayers.org. If you're familiar with JavaScript, try viewing the source -of the examples to get an idea how the OpenLayers library is used.
- -OpenLayers is still undergoing rapid development, so expect a lot to change -in the next few weeks and months. We need your support! Please check the wiki for the very latest updates and -documentation, and thank you for taking an interest.
