Developing Web GIS Apps with Open Source API

This course teaches you how to build GIS web portal using open source GIS end to end solutions. Includes open source GIS software including QGIS, PostGIS, GeoServer, and OpenLayers which all together can deliver the complete GIS solution. OpenLayers makes it easy to put a dynamic map in any web page. It can display map tiles and markers loaded from any source. OpenLayers has been developed to further the use of geographic information of all kinds. Attendees will learn how to create browser-based map applications and display data from a variety of sources. Basic JavaScript syntax will be covered. In GeoServer attendees will learn how to load, publish, and share geospatial data with GeoServer. Discussion will include navigating the GeoServer user interface, OGC web services, styling data with SLD, and tile caching with GeoWebCache.
