Quantitative updating of land use information on 1:50,000 scale topographic maps using spot landsat thematic mapper imagery

This report gives the results of a study carried out in the Remote Sensing Department of the National Aerospace Laboratory (NLR) in The Netherlands concerning the updating of land use on topographic maps using remote sensing information. It was found that SPOT multispectral imagery is less suitable for land use classification purposes than...

Improvement of classification results from satellite imagery using context information from topographic maps

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...

Improvement of classification results of satellite imagery using context information from a topographic map

The study described in this article examined 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 to date and a large number of classifications can be distinguished. However, the information still leaves much to be desired, with...

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...

A systematic worldwide landcover of satellite mosaics

The gap between the number of detailed satellite images (of e.g. Landsat) recorded and the number actually used is increasing rather than decreasing. A major cause for limited use of potentially available imagery is the cost. A complete range of national, continental and worldwide applications has not developed for that reason. A sketch is made...

Landuse inventory using landsat thematic mapper imagery to study environmental pollution

The possibility to obtain up-to-date information on agricultural landuse from Landsat TM imagery by means of classification was investigated in a pilot study on a 50.000 ha area. The pilot study was a preparation for a national exercise. The accuracy of the results for the most important classes varied between 80 % and over 95 %. The result was...

Integrating satellite data with information from topographic maps: Methods and applications

Landsat thematic Mapper, SPOT panchromatic and SPOT MSS imagery from 1986 were investigated for their capabilities of keeping topographic maps up to date. A method was developed for combining topographic information with satellite information. The optimum product is useful for visual updating of topographic maps of scale 1:50.000. In the study...
