What's the best solution for OCR analysis of handwritten text strings that appear on a map?
More in-depth explanation of what I'm looking for:
I'm working on a large data processing effort involving a library of engineering drawings. These are for utilities, so the drawings are essentially street maps overlaid with features like transmission lines and code numbers related to these lines. The code numbers are mostly handwritten–very neat and consistent engineer's handwriting, but handwritten nonetheless. Also, because the code numbers correspond to transmission lines, they are all over the drawing, at different angles as they follow the lines. I'd like to find an OCR solution for harvesting the code numbers from these drawings; does anyone have any suggestions?
A similar problem would be: given a city map, extract all the street names, addresses, and points of interest.
