Description
The Multilook tool only supports radar data in image space.
Radar data in map space such as, Capella GEC, Capella GEO, and outputs from the Apply Geometric Terrain Correction tool are not supported.
Solution
The Multilook tool outputs downsampled radar data in image space.
When the radar data is in map space, use the Copy Raster tool instead to accomplish the downsampling. Specify the Cell Size parameter in the Raster Analysis section of the Environments tab. To reduce artifacts, select the Bilinear option for the Resampling Method parameter on the Environments tab of the Copy Raster tool, as well as in all subsequent tools in the workflow.
