I'm working with multidimensional (grib2) raster data, and values for many (but not all) of the variables are incorrect when added to an ArcGIS Pro map (Add Data --> Multidimensional Raster Layer). Here's one example, which is wave direction:

The values when added to ArcGIS Pro:

The values when the same data is added to QGIS:

The same incorrect values are also produced when publishing to ArcGIS Image as a hosted imagery layer. Does anyone have insight on why this might be?

Hi Joseph,

There could be an issue in previous release on reading compressed data, but it has been fixed.  The top layer is multidimensional raster layer where the min and max in the legend is on-the-fly estimated values. the second layer is the CRF here the statistics is calculated by scanning all pixels. it is in Pro 3.0 beta 1.

Thanks Hong Xu. Is there any way for me to get access to the Pro 3.0 beta? Or any other advice for making this data usable in the ArcGIS platform while we wait for the 3.0 release?
