Template:Merge Elevation Rasters
Merge Elevation Rasters
The Merge Elevation Rasters tool creates a new raster by merging two or more elevation rasters with priority into a new raster. The resolution of the resulting raster will be the resolution of the principal raster (raster 1). The extents of the resulting raster be expanded from the base of the extent defined by raster 1 to include all other rasters.
It should be noted that this operation can result in very large rasters. If a low priority raster has a coarser resolution than the primary raster, it will be super sampled to match the resolution of the primary raster in the areas where this raster extends the domain. This super sampling does not provide new data. For this reason, the Interpolate Priority Rasters tool is recommended ahead of using this operation.
Input parameters
- Raster 1 – Select the first elevation raster to be merged. This raster will be given the highest priority during the merge.
- Blend distance – Enter a distance for the edges of the raster to be blended when merged with another raster. This option can be set for each raster being merged.
- Raster 2 – Select second raster to be merged. This raster will have the next highest priority.
- Raster n – Additional rasters can be added to the merge with lowering priority. These parameters appear as needed. The last field should be left blank
Output parameters
- Merged raster – Enter a name for the new merged raster.
