Automatic lettering of cadastral maps

A system for the automatic placement of names on cadastral maps, using a method which, because of its generality, can be easily applied to other types of maps is presented. The method is based on a robust algorithm that, after having detected character strings on the original paper map, encases them with rectangles, and searches for the most convenient location where to place such rectangles on the computer version of the map. The system is part of an operative package working to feed the GIS of the Italian Land Register by means of the automatic interpretation of cadastral maps. Results obtained on a sample set of more than 100 maps are reported.<
