Template:Interpolate Priority Rasters
Interpolate Priority Rasters
The Interpolate Priority Rasters tool creates a new dataset for a selected geometry (UGrid/Mesh2D/Scatter Set) by interpolating from multiple rasters according to a user specified priority. Each source is added to the list in priority order. If a value is not obtained when interpolating from the highest priority source, the tool looks for a value in the next source until either a value is found or all sources are exhausted.
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.
Observation profiles can be extracted from the surfaces to visualize the differences. If significant differences exist, the Blend Raster to Edges tool and the Clip Raster from Elevations tool can be used to correct them.
It should be noted that the output dataset must be mapped to be the Elevation of the target geometry if that is desired. It is not mapped automatically.
Input parameters
- Grid – Allows selecting the geometry that will receive the interpolated raster values.
- Default dataset – Allows selecting a dataset in the project to use as the default values for interpolation.
- Resample algorithm – Select the method that will be used for interpolation.
- "blinear" – Select to use the linear interpolation method.
- "nearest_neighbor" – Select to use the natural neighbor interpolation method.
- Raster 1 (highest priority) – Select the raster that will be given highest priority during the interpolation process.
- Raster 2 – Select the raster that will be given the next highest priority during the interpolation process.
- Raster n – Additional rasters may be selected and given priority in the order they are selected.
Output parameters
- Output dataset name – Allows setting the name of the new dataset on the specified mesh, UGrid, or scatter set.
