You can interpret the map as an image and do standard image processing on it, for examle using OpenCV. For instance, you can run different feature detectors/descriptors on the map and use those. An example of doing exactly that is provided in the mapstitch package that allows aligning maps which each other. The code for converting a map to a cv:Mat is here.
