+FOSS4G: Was the FOSS4G presentation too early for you this morning? The presentation is available in Open Office Impress format, and the examples are available as well.
+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.
