Georeferencing-scripts is a project mainly written in JAVA and PERL, it's free.
A bunch of scripts to help georeference a bunch of digital map images, using GDAL as the backend.
This repository contains a bunch of scripts I've been using to help automate georeferencing some digitised old paper maps.
There are two main work flows I've been using so far.
The third folder "common" is for the common scripts, that can be used from the output of either of the above two approaches.
More details can be found in each of the folders.
