| Mar 15, 2023 at 6:54 | comment | added | bugmenot123 | It might seem esoteric but I would be afraid of it being lossy in some circumstances due to floating point numbers etc. I want to do analysis on pixel-perfect aligned rasters, not 99.99% aligned ones. | |
| Mar 15, 2023 at 6:38 | comment | added | Tom Brennan | What is the issue with a vector mask? I did a basic test with a raster with data pixels surrounded by NoData pixels, and a projected CRS. I used Raster Pixels to Polygons to create a polygon mask, and then Clip Raster By Extent with the polygon layer as a vector mask. The output layer was aligned to the source raster. | |
