Hello, I'm using NASA digital elevation raster files (file extension *.hgt from the NASA DEM) in ArcGIS Pro. NASA provides an additional *.NUM file containing information which identifies the data source for each raster cell. NASA describes this as a scene layer. I want to read this NUM data into ArcGIS and analyse it (e.g. using the reclassify tool) so I can visualise the sources of data.
The problem: I can't figure out how to bring the *.NUM data into ArcGIS. I've tried searching for guidance in the ArcGIS Pro user help and searching the internet, however can't find a solution or information on how to pre-process the file. I've also tried using Toolbox tools (such as the Binary to Raster tool), however ArcGIS doesn't seem to recognise the NUM file type. Does any one know a way to bring this type of data into ArcGIS Pro? Or what pre-processing steps are needed? The attached image shows how the files appear (unfortunately their size is too large to attach to this post). This is what NASA says about the files.
I hope you can help, or share any ideas... I can't think what else to try!
