ArcScene hillshade error - Bathymetry data

TannerAcquisto

I am attempting to create a hillshade for some bathymetry data (.grd format) and the output is close, but still not usable. I have attached a picture of the issue as well as a link to download the dataset (G1-G2.grd). As you can see, the hillshade is partially overlapping the data in some spots and also colors other areas outside the dataset black.

I am using the Hillshade tool under the 3D Analyst Tools, which has worked for me in the past. Any idea what causes this phenomenon?

Thanks,

Tanner

That works! Under symbology, I set the "Display Background Value" to zero, and assigned no color to it. I guess having a color there was causing some issues when rendering multiple layers.

Thanks for the help, Dan!

perhaps the extent is classed as nodata, have you tried to set the color of 0 (and/or nodata) to nothing?

By itself, the hillshade looks fine, only the entire extent has been colored black for some reason. This appears to also be causing issues with overlaying on the original data.

can you toggle off the grid above the hillshade to see what it looks like?
