ABSTRACT
TLS is a cutting edge technology used to map land surface features and it is a source of high resolution DTMs. Used in mapping river banks, this technology is able to deliver high resolution models of these geomorphologic and hydrologic features. While the processing of DTMs obtained using TLS technology is similar with the processing of DEMs obtained using LIDAR technology, several features of the river banks require operations that are different compared with the operations on LIDAR DTMs. In this context, a script for GRASS GIS package was created, in order to create a generic framework for generating and analyzing DTMs of river banks and obtained using TLS. While the script is created to be used with GRASS GIS, the logic of the framework can be used to port the framework in any GIS package that has enough scripting capabilities.

Keywords: river bank, DTM, TLS, GRASS GIS
