Hi, I have several rasters in the same projection, but with different coordinates for the upper-left corner. I need to do some modeling though BandMath functions, but it seems to require perfectly alligned rasters. I've managed to solve the problem in the past through layer stacking, but I think that will only work if they are all of the same data type(?). I now need to model with rasters of byte, long, and double types. What would be the best method for aligning these? Is there a resampling function I haven't found that will create a new raster file using the header info from a separate raster? Thanks, -Eric
