The choice has to be made between interactive editing and automatic procedures. An attempt has been made by IGN France on the occasion of a land-use inventory updating. More precisely, the aim was to adjust a new delineation of land use areas to an old one. Digitization is performed in raster mode through a scanner. After skeletonization, control points are interactively identified in order to calculate a global transformation which is applied to the vectorized boundaries, and eliminates main distorsions due to variations in drawing materials. Then the boundaries are processed in raster mode in order to correct new lines which are exactly adjacent to old ones, or which define with an old line a micro-area. The results seem rather good but introduce local distorsions due to the very local approach of the process. To avoid such distorsions, we have to improve the software in using shape considerations in replacing very local operations by more regionalized operations. It is an interesting example of the successive or simultaneous use of several data structures to solve an updating problem.
