When to use an online tool

Online georeferencing tools are a great option if you:

  • Aren’t comfortable using desktop GIS software
  • Want to quickly georeference an image
  • Want to look at the georeferenced image online and don’t plan to work with it further

Online tools require you to have only a basic knowledge of the georeferencing workflow to get started.
