Hi. I read your project description. Maybe I can help you.
First, I am survey and cartography engineer working with various type of data (raw field, maps, online data, photogrametry, etc ) for creating maps and models.
Very experienced with georeferencing maps whit coordinates or base map underlay, as I worked with old cadastre map for in digitizing process , and converting raster to vector.
Can you share you maps with me???
