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. 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](http://MapKnitter.org) or read on for more documentation! ## Exporting 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: https://publiclab.org/wiki/mapknitter-cloud-exporter Learn more about [exporting maps in MapKnitter here](/mapknitter-exporting). ## Activities [activities:mapknitter] **** ## Questions [questions:mapknitter] **** ### Advanced * [Decisions with distortions](https://www.youtube.com/watch?feature=player_embedded&v=S8uUM3p3_Bk#!) - Learn about the design process of stitching maps when images are highly distorted or include tall buildings.
