Web Map Interface
This training was part of ADB’s ETESP Package 39 Part 2 project and was carried out last month, which was attended by staff from Aceh’s Forestry and Plantation Office.
The training course is built around the concept of data severs, map servers and application servers and the open source software required at each tier to establish a scalable architecture capable of delivering spatial web services and web applications.
Outcomes
Participants will be up to date with the latest geospatial data standards and exchange formats which enable interoperability.
On completion of the training course, participants will have developed a map viewer framework using open source software which distributes spatial web services and web mapping applications.
Length
The length of the course is approximately 5 days
