Problems creating terrain

[Anonymous]

Hi,

I’ having some problems creating a terrain on HEC-RAS 5.0.3 RAS Mapper. I was trying to create a terrain as simple as possible with one raster (.tif) I made in ArcGIS from point data.

When I try to create a terrain the computing just stops at “Creating .vrt…” without any error messages (see below). I would appreciate any advice, Thanks!

Br,
Roy

I am having the same problem. I thought it was because the size of the DEM file, but it wasn’t because I resampled the DEM multiple times from 1×1 (247Mb) cell size to 2×2 (87Mb) and 4×4 (25Mb). With all the DEMs I am having the same problem.

Tengo el mismo problema. Pensé eque era por el tamaño del archivo del DEM pero no era porque remuestre el DEM varias veces de celdas 1mx1m (247Mb) a 2x2m(87Mb) u 4x4m (25Mb). Con todos los DEM estoy teniendo el mismo problema.

For me the solution was to save the hec-ras project (.prj), the DEM (.tif) that had to be processed, and the destination terrain file (.hdf) to a directory path with no special characters (no à, ò, ù, …)
