Georefrencing! 🌐

Georefrencing is the creation of control points on map and using georefrencing software like what is built into QGIS to project an old or otherwise unprojected map onto a modern map using GIS software.

Lately I’ve been doing more and more of it. I started learning it for reprojecting historical aerial photos but lately I’ve discovered how powerful the software is projecting both historical maps and maps that are in government reports and permits.
