Align Rasters

Question

Hello,

I have two rasters of the same cell size and spatial reference but the cells are not perfectly aligned- how do I correct this?

I have read the post from the following link which suggests using the georeference tool, but my understanding is that if I use that I will create some warping which I do not want.

Any thoughts?

Thanks!

I've got a tool that will automate aligning rasters in ArcGIS Pro - https://www.arcgis.co/home/item.html?id=4f5e9d4e3b974890991d33e7e5251231

Snap Raster (Environment setting)—ArcGIS Pro | Documentation

How the Snap Raster environment setting works—ArcGIS Pro | Documentation

as well as Cell Alignment and the Cell Size environment setting.

A copy raster to get one aligned to the other should work if the differences in alignment are within a cell size.
