Image Georeferencing Using GeoLibre in the Browser Learn how to georeference images, scanned maps, and historical maps directly in your web browser using GeoLibre, with no desktop GIS software required. Video tutorial: https://youtu.be/lbioujkDSG0 In this tutorial, I demonstrate how to georeference a campus map by selecting ground control points, choosing a transformation method, evaluating residual errors, and aligning the image with a basemap. You'll also learn how to export the georeferenced result as a GeoTIFF, reload it into GeoLibre, compare it with the basemap, and share the finished map online. GeoLibre is a free and open-source, cloud-native GIS platform that runs in the browser, on desktop and mobile devices, and in Jupyter notebooks.
