A vector approach for automatic interpretation of the French cadastral map

Abstract

This paper deals with cadastral maps interpretation device. The challenge is to propose a complete reconstruction of the parcel's areas and buildings to use with geographic information systems. It is based on a low level primitives extraction and classification. As this low level may be quite noisy, an interpretation process classifies medium level objects and manages convenient processes to the particular extracted shape. Then, a reconstruction step is used to label the parcels areas and determine the final land partition. We present at first the vectorization strategy in our particular context then we will discuss the different tools used to reach the higher level.
