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 MapKnitter.org 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. Learn about exporting maps in MapKnitter 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.
- Decisions with distortions - Learn about the design process of stitching maps when images are highly distorted or include tall buildings. This tutorial is in Photoshop, but the techniques are applicable to MapKnitter as well.
- Infrared multispectral compositing (no video, in progress) Learn how to combine an infrared dataset with your map to assess photosynthesis. (Also: learn how to collect infrared imagery)
