Software tools

In the framework of different research projects carried out at TU Bergakademie Freiberg and Forschungszentrum J├╝lich, some software tools were implemented for use with Definiens Developer 7 / eCognition Developer 8 / eCognition Developer 8.7, ENVI/IDL bzw. IDL Virtual Machine. The tools can be downloaded for free use here. Please let us know your experiences!
