I was using the -te option, but now that I have converted the basemap into a GTiff (and confirmed the details via gdalinfo) I have tried the -crop_to_cutline option you described, and it fails without output or error: gdalwarp -cutline ./output43264.tif -crop_to_cutline output4.tif outputN.tif

I think I am georeferencing the maps fine now, and turning them into GTiff's. But... I am not sure I am any closer to the goal of getting an output .png that has the same x/y dimensions as the basemap, and can directly overlay.

Perhaps the part I am missing is that all I have is a plain .png file and the edge coordinates - the file is not a TIF with this information embedded, and gdalwarp doesn't know where to begin.

I'm absolutely interested - I'd hate to bang my head against a wall that you've already banged down. Thanks!
