Hillshade Artifact

Hi all,

When I'm running Hillshade Function (Raster Function) for DEM mosaic I get artifacts. See Attached

I use ArcGIS Pro 2.6. I didn't get it on 2.5 version

Any ideas what causing it?

Thanks

Adi

Do you get the same result using all 3 options?

and it could be this issue

Thanks for the reply,

It happens only when using 'Raster Function' on mosaic dateset

When using the 'Hillshade' in geoprocessing or, calculating 'Raster Function' on the original data it looks ok.

I'm doing it on the same mosaic dataset I created on 2.6

Also, in Arc Map 10.7 it looks ok

Hillshade function—ArcGIS Pro | Documentation

there is some mention of "mosaic" datasets for one of the parameters

Disable default edge pixel interpolation .... Use this option when the mosaic dataset containing your elevation raster data consists of overlapping items or tiles.

although it seems present in both the 2.6 and 2.7 documentation, but I haven't done a complete comparison between the help topics
