Updating Large Scale Topographic Databases in Italian Urban Areas with Submeter QuickBird Images

[摘要] This paper presents some tests for the updating of the Italian Raster RegionalTechnical Map (RRTM) at 1: 10000 scale and of the Italian Vector Technical Map (VTM) at1: 5000 scale using a submeter Quickbird imagery collected in a near flat urban area of theNorthern Italy. Results show that the updating of the 1: 10000 scale cartography was alwayspossible, while a rigorous updating of 1: 5000 scale cartography was possible only in fewsituations. Results are discussed with reference to the specifications required for the 1: 10000scale and 1: 5000 scale topographic databases (DBs) production of the Lombardia Region,which is a reference for metric mapping purposes in Italy.
