No file currently selected for upload

Welcome! This site lets you upload an aerial photo, field sketch or map extract and overlay it onto a modern map. There are 4 steps:

  1. Upload an image file (JPG or PNG) from your hard drive (if it's not too large)
  2. Crop any white space or margins
  3. Tag it — at least 3 locations, then ...

Zoom, Stretch, Rotate, Scale!

We'll load it onto a modern map and you can rubbersheet it to fit.


Jump back and forth or come back later and pickup where you left off.

  1. Time spent determining the exact corners will guide how close our initial fit is.
  2. If you put the corner in as a trench map reference, such as 57c.J.16.b.3.1, then we will calculate the latitude and longitude for you.
