Updating land-use information on topographic maps using satellite imagery : combining the advantages of two accessible sources of geographic information

This paper examines the possibilities of using Landsat Thematic Mapper images for updating land-use information on topographic maps. Information obtained from satellite images can be kept up-todate and a large number of classes can be distinguished. However, the quality of the information still leaves much to be desired, with a reliability of no...

The potential of combined use of satellite data with topographic information

Landsat Thematic Mapper, SPOT panchromatic and SPOT MSS imagery from 1986 were investigated for their capabilities of keeping topographic maps up to date. Topographic information was digitally combined with satellite data using raster techniques. From the map line-information on roads, naming-conventions, water and housing was used to cover a...
