Dear GRASS developers and users, I am using GRASS GIS for some hydrological applications. For some questions like flood prediction it is useful to estimate the travel time of surface water in a basin to the outlet. Therefor I've developed a raster program "r.traveltime" which calculates the travel time for each cell in a basin from outputs of r.watershed and r.fill.dir. There is much literature about this procedure available but there's a lag of available software (GRASS and even ArcGIS do not come with this function). The personal need an the lag of available programs were the reason for me to develop a new program for GRASS GIS. I am not a programming expert, so the program is very simple and far away from being perfect. I submitted this tool to the GRASS Wiki addon page.
In November I have already posted r.traveltime to the GRASS weblist mailing list. Recently I've found some bugs in the program. I hope it works correctly now. r.traveltime is available here: http://home.arcor.de/jesbergwetter/main_sw.html Best regards Kristian Förster Viel oder wenig? Schnell oder langsam?
