Sketch Map Tool: Participatory mapping in OSM and beyond
summary
Sketch Map Tool generates printable OSM-based PDFs, accepts photographed or scanned annotations, and returns a geo-referenced GeoTIFF plus GeoJSON vector extraction of hand-drawn polygons and multi-color markers. It uses an automated QR-based georeferencing and pixel-difference pipeline (Python/Flask/Celery) to match scans to originals, supports color differentiation (red/blue best), and includes a quality report for road and amenity coverage; deployed in Brazil, Mozambique and Madagascar and proven usable in field workshops.
