If you have a GIF or JPG map or satellite image of the area that is
more accurate than our maps, enter the URL here. We will put up a map
browser which you should zoom in on until it overlaps the area in your
image. At that point you should identify two points on the map (preferably
at opposite diagonals) and we'll use those to calibrate the image to
match the map. If your image is accurate enough, you can get a very
precise latitide and longitude for your building this way even if the
building isn't visible on our own Census Bureau maps.
