Template:VRT from Rasters

VRT from Rasters

The VRT from Rasters tool creates a VRT from multiple rasters according to a user specified priority. Each source is added to the VRT in priority order.

It should be noted that rasters from different sources may have errors or differences from one another for a variety of reasons. Principal causes of incompatibilities between rasters include the changes between the times when each source was gathered, differences in survey methods, and slight adjustments to datums. Large raster differences can result in discontinuities in the surface. These discontinuities can have ramifications on the hydraulic results for simulations of flow over the combined surface.

Input parameters

• Resample algorithm – Select the method that will be used for interpolation.
  • "bilinear" – Select to use the cubic resampling method when warping a raster's projection.
  • "nearest_neighbor" – Select to use the nearest neighbor resampling method when warping a raster's projection.
• Raster 1 (highest priority) – Select the raster that will be given highest priority during the VRT creation.
• Raster 2 – Select the raster that will be given the next highest priority during the VRT creation.
• Raster n – Additional rasters may be selected and given priority in the order they are selected.

Output parameters

• Virtual Raster Table (VRT) file – The base name of the VRT file to be created and loaded into SMS.
