MapKnitter

*Part of the [Grassroots Mapping Curriculum](/wiki/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. <iframe width="640" height="480" src="https://www.youtube.com/embed/0h6MBH6f2js?rel=0&amp;showinfo=0" frameborder="0" allowfullscreen></iframe> MapKnitter can make maps from any image source, but it was designed for making maps with aerial photos from balloons and kites.
