Description

GeoServer is an open source  server-side software written in Java that allows users to share and edit  geospatial data. It also provides great flexibility in map creation and  data sharing.With this fast-paced, hands-on guide, you'll start with  various GeoServer Layers & adding information on the map using  different styles. Then you'll learn to deploy a spatial database,  PostGIS, in tandem with GeoServer.  Next, you’ll dive into an important  technique to improve the speed of your web map application. Moving  further you’ll enable authentication on the front and back ends to  protect sensitive map data, and how to deliver sensitive data to your  end user. Finally, you’ll put your web application into production &  look at the hosting of the OpenLayers, GeoServer, and data aspects of  your application. 

Who this course is for:

  • This course is aimed at GIC analyst, web & mobile app developers that will help them serve their geospatial data, maps, and algorithms for consumption on the web, mobile, and desktop apps.
