Hi, Folks,

I'm trying to create a mosaic dataset of about 100 clipped rasters. However, when I run the Mosaic to New Raster function, the resulting mosaic shows the unclipped rasters. See for example:

The mosaic should look like this:

But comes out looking like this (the clipped portions of map #89 are showing):

Here are my mosaic settings:

Help! What am I doing wrong?

Thanks!

Hannah

I resolved this by taking 2 steps: first, I exported the rasters as tifs using a batch Copy Raster function. Then I changed the Mosaic Operator from "Last" (ArcGIS Pro's recommended operator) to "First" to address layer ordering, which is crucial in this mosaic.
