What is CATCON ?

CATCON is the name of a software contest organized by the ISPRS Commission VI. The main objective of the contest is to promote the development and dissemination of good/user-friendly software packages, videos as well as data sets for computer assisted teaching(CAT). In general, the software or dataset should be non-commercial and should be provided to the users on free of charge.
    The first CATCON was organized at the ISPRS Vienna Congress in 1996, the CATON2 at the ISPRS Amsterdam Congress 2000, and CATCON3 at the ISPRS Istanbul Congress 2004.
