OpenLayers Training in Hyderabad India

OpenLayers


OpenLayers is an open source JavaScript library for displaying map data in web browsers. It provides an API for building rich web-based mapping applications. GeoExt provides a suite of customizable widgets and data handling support that makes it easy to build applications for viewing, editing, and styling geospatial data.


This one day course will introduce attendees to OpenLayers and GeoExt. Attendees will learn how to create browser-based map applications and display data from a variety of sources. Anyone interested in web mapping is encouraged to attend, but familiarity with basic GIS concepts is suggested and experience with JavaScript is preferred, as is experience of creating simple web pages.
