I have a multiple raster datas (~ 450 DEM´s) and I want to merge them into a new single raster data.
I want to use the mosaic DEM to determine the slope.
Does anyone have any idea how to merge them together into a new raster data the easiest way?
I tried it with the tool “Mosaic to new raster”. But maybe there is a better way and I don´t know it yet?
Although the input datas (coordinate system, number of brands, pixel type,...) are the same,
the following error appears with the “Mosaic to new raster”-tool:
Error 000999: Failed to get raster. Please check if the input parameters is correct.
I was wondering if this is because the raster data has a compression (RLE).
However, the individual raster datas are displayed in ArcMap.
Does anyone know if it could be due to this fact? Or what else could it be?
I am very grateful for any help.
