Conversion between Singapore Coordinate System SVY21 and World Geodetic System WGS84

In August 2004, Singapore Land Authority introduced the new coordinated cadastre system, SVY21.

Recently, I need to use data from both onemap and google map, and the difference in coordinate systems made it pain in the ass to work with. So I wrote a Python script to convert to and from both coordinate systems.

Basically I used the geometry service provided by Esri Arcgis Online at ” http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer

The script is hosted on https://github.com/zkkmin/coordconvert .

Since I wrote it mainly for my task requirement, you might need to modify it for your own usage 😀
