OpenLayers is an Open Source map viewing library, written in pure JavaScript. The OpenLayers library provides a JavaScript API which makes it easy to incorporate maps from a variety of sources into your webpage or application. OpenLayers currently has support for OGC WMS layers, navigation, icons, markers, and layer selection. Lots of other features are slated to be added soon!
