Dear all, Im processing the PS for some study area and i need very high precision of the product. Thus im decided to use external DEM delivered by LiDAR. However, i try to import it as tiff or envi format. The software return me an error. In case of tiff format t was writtend that .sml was not found. I have this dtm as Arcgis raster format and I dont know how to export to to sarscape Also extra question: what value assign to NoData value (i mean -9999,NaAor what? ). Could sombody help me? Regards

SARscape itself cannot import a DEM in any ArcGIS raster format. It can only import DEMs in TIFF or ENVI format. But ENVI can probably import your ArcGIS raster image, and then export it as a TIFF or ENVI format file that you can then import into SARscape. Is your DEM an ESRI geodatabase? Or is it some other raster format that ArcGIS generates? Another option is to save out the DEM as an ENVI-format or TIFF-format raster from within ArcGIS. SARscape's TIFF or ENVI importer should then be able to import the DEM without error. Best, Peg Harris Geospatial Solutions
