mapknitter
An open-source web tool for stitching aerial photos into georeferenced maps using a browser-based interface.
What is mapknitter?
MapKnitter is an open-source web application that allows users to upload aerial photographs—such as those from balloon or kite mapping—and align them over base maps to create georeferenced composite maps. It solves the problem of creating custom maps without expensive GIS software by providing a browser-based tool for manual image placement and export in multiple formats.
Community mappers, environmental researchers, educators, and DIY enthusiasts who need to create detailed maps from low-cost aerial imagery for local projects, advocacy, or scientific monitoring.
Developers choose MapKnitter for its fully open-source stack, ease of self-hosting, and integration with the Public Lab ecosystem. It offers a unique collaborative web interface for manual map stitching, making it ideal for grassroots mapping efforts where automated solutions are impractical.
Overview
Upload your own aerial images, position (rubbersheet) them in a web interface over existing map data, and share via web or composite and export for print.
