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.
