Since the 2022.02 you can configure a localDatumCoverageTileArchiveFile and zoomLevel. The grid is first converted to a temporary grid that matches the configured zoom level. Every grid cell in this temporary grid contains the height from the cta and the global water level from the original grid. A bilinear interpolation is applied to the global water level of the original grid. This is the same as in the spatial display.
