Bayu Kurniawan R Webblog – MapServer for Windows (MS4W)

Welcome to MS4W, the quick and easy installer for setting up MapServer For Windows and its accompanying applications (e.g., Chameleon, MapLab,etc.). The purpose of this package is to allow novice to advanced MapServer users to quickly install a MapServer development environment on their Windows systems. The reasons for needing to do this are diverse but, in general, this package supports: developers who want to get to a stable state quickly, trainers who need an easily-installed configuration identical across multiple installs, and novices who need help just getting all the needed bits and pieces together.

QGIS FORUM – Welcome to the wonderful world of opensource GIS!

QGIS FORUM – Welcome to the wonderful world of opensource GIS!

Welcome to the wonderful world of opensource GIS!

We love opensource GIS software – and QGIS 2.0 in particular. On this basis, we have decided to create this website, in hope that it will become a valuable resource, that many people will find useful.

The main features of the website are:

  • The forum, where you can post questions and discuss opensource GIS
  • The QGIS 2.0 tutorial, where we show you how to quickly get started with QGIS
  • The QGIS 2.0 API (older API’s also available)
  • The IRC chat room, where you can get in contact with the developers of QGIS
  • Latest news from the opensource GIS world
  • And hopefully, in time, much more exciting and free content
