I have a question regarding DEM. I have downloaded SRTM DEM 30 m and I did a mosaic for the data using Mosaic tools in Arcmap to a Mosaic to a new raster. However, I got a DEM raster with values of 0-255 . I need to have a DEM values with meters not with the values of 0-255. I did convert the raster to 32-float but I still get the same value 0-255. and the cell size is 0.0002777.
Any idea how to convert DEM raster with values of 0-255 to values represent elevations?
