1. If you have multiple raster pieces of the same geodata type, merge them into a single raster using the ArcGIS Pro Geoprocessing Mosaic To New Raster tool.


Result:


2. Ensure all geodata rasters use the same projection. If any raster has a different projection, use the ArcGIS Pro Geoprocessing Project Raster tool to align them.


3. Use WGS_1984_UTM projections and apply correct projection number based on your location.


4. Apply correct geodata names and NoData attribute.


Topographical data must have specific names:

  • The Digital terrain model must be named elevation.tif 
  • The Building height grid must be named building_height.tif 
  • The land use (or clutter) grid must be named clutter_classes.tif 
  • The clutter heights (typically vegetation height) grid must be named clutter_height.tif 


Each raster must have NoData attribute: -9999.


To apply correct naming and required NoData attribute, use Copy Raster tool in ArcGIS Pro Geoprocessing.


5. If the building data is a vector file, convert the building vector layer to a raster using the ArcGIS Pro Geoprocessing Polygon to Raster tool.


6. Save all your geodata files in one catalog.
