Part of the Grassroots Mapping Curriculum series.

MapKnitter is a free and open source tool for combining aerial images into a map, or composite image. Informally, we call this "stitching a map" and it's useful if you have many images of overlapping or identical areas, and getting either a web map or a printable map from your photos.

MapKnitter can make maps from any image source, but it was designed for making maps with aerial photos from balloons and kites.

Start using or read on for more documentation!


Once you're map is complete, you can download it as a single image in JPG and other formats. Read about the new Cloud exporter here:

Activities should include a materials list, costs and a step-by-step guide to construction with photos. Learn what makes a good activity here.
