I want to know the algorithms/logic used in pre defined routines like ground routine, building routine etc. Any reference papers/work which has been used for this tool. Thanks.

Axelsson, P., 2000, “DEM GENERATION FROM LASER SCANNER DATA USING ADAPTIVE TIN MODELS”, International Archives of Photogrammetry and Remote Sensing, Vol. 33, part B4/1, ISPRS, Amsterdam 2000, pp. 110–117. Most of the other classification routines are not based on specific algorithms and have no direct references. Author Posts You must be logged in to reply to this topic.
