I have a problem with the operation r.los in winGrass(native). I have been testing different maps and when a distance is greater than 80-100 pixels (map pixels) a system error is thrown. To put an example, in spearfish data base and the elevation.dem map, grass fails from 2524m on up (with the height of the observer set to 1m) The command would be: r.los input=elevation.dem output=los coordinate=599505,4921010 max_dis=2525 The error that is reported is a system error: ""r.los.exe there are encountered to problem and needs to close"" Thanks and regards." defect closed major 6.4.0 Raster svn-develbranch6 fixed wingrass r.los marco.pasetti@… x86-32 MSWindows XP
