On this site I will primary host the two plugins I have created and possibly others for the program SportTracks.

Plugins

GDAL plugin - a plugin which provides access to GDAL libraries for other plugins.

Custom map plugin - a plugin which will allow use of custom maps in SportTracks. Maps can be with geographic data or just common image formats.

Other

In the initial state of development of the map plugin I implemented an algorithm for converting Swedish projection RT90 to and from WGS84 published by Lantmäteriet. I have found out that this is something many like to able to do so here is a small tool, a .Net2.0 compatible executable:

CoordTransform.zip (if you want the source code, find me in this thread)

On Lantmäteriets web-site there also exist an on-line conversion tools between multiple projections used in Sweden.
