Application:
Geographic Features Extraction by use of Satellite Images and
Vectored Imprecise Databases



We describe here a system able to identify cartographic objects on SPOT images using prior vectored geographic databases, and to modify these databases (precision and updating) [P. Dhérété, 1998]. Prior data and expert knowledge are used to help image analysis. Moreover imprecision of information sources is taken into account by fuzzy logic approaches.
