About

This project is a plugin for QGIS 3 to perform interactive raster georeferencing. The plugin was originally made to replace a workflow where digitizers would use Google Earth to interactively georeference a raster and the tools (move, rotate, scale...) found in that software have been reimplemented. Compared to the standard raster georeferencer tool of QGIS, which needs control points and an export, this plugin allows the visualization of the result immediately, on top of the other layers of the map.

Install

From the QGIS plugin registry

In QGIS, open the "Plugins" > "Manage and install plugin" dialog. Install the "Freehand raster georeferencer" plugin.

From Github

Use the master branch:

  1. Download a ZIP of the repository or clone it using "git clone"
  2. The folder with the Python files should be directly under the directory with all the QGIS plugins (for example, ~/.qgis2/python/plugins/FreehandRasterGeoreferencer)
  3. Compile the assets and UI:
    • On Windows, launch the OSGeo4W Shell. On Unix, launch a command line and make sure the PyQT tools (pyuic5 and pyrcc5) are on the PATH
    • Go to the plugin directory
    • Launch "build.bat" or "build.sh"
  4. The next time QGIS is opened, the plugin should be listed in the "Plugins" > "Manage and install plugin" dialog

A legacy version for QGIS 2 is in the qgis2 branch.
