GeoDMS is a fairly obscure geographic object-oriented programming language written in C++ by Object Vision (http://www.objectvision.nl/geodms/). I'm using it to analyse location-dependent renewable energy options, with or without the Vesta model, also by Object Vision and the Dutch Environmental Planning Bureau (http://www.pbl.nl/).
I have frequent questions on how to do things in GeoDMS. If anyone else is working with this language, it would be great to exchange knowledge! Please respond to this threat. Thank you.
