Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 Thematic Mapping by Satellite - A new tool for planning and management J.W.van den Brink & R.Beck DHV Consulting Engineers, Amersfoort, Netherlands H.Rijks Geodetic Department of the Delft University of Technology, Netherlands ABSTRACT: The new generation of "high-resolution" remote sensing satellites will increase the number of applications drastically. It is believed that the imagery of these new satellite systems will play a substantial role in the planning and management practices of land and water. Even in countries where a well- developed structure for geo-data processing exists such as the Netherlands, satellite remote sensing forms an important additional source of information in planning and management. This latter statement is also supported by the encouraging results of the case study presented in this article. The objective of the study was to evaluate the possibilities of the new satellite imagery and to present the obtained information in a way accessible to planners, etc. Therefore the concept of the "Satellite Thematic Map" was adopted as a user- friendly endproduct useful for a large user community. In the article, characteristics of the Satellite Thematic Map for the "Kromme Rijn " Area in the Netherlands are discussed. RESUME: La génération nouvelle des satellites de télédétections a "haute résolution" augmente le nombre d'applications de façon dramatigue. Ces systèmes spatiales joueront une rôle substantielle dans les techniques de planification et aménagement des ressources naturelles. Aussi bien dans les pays qui disposent d'une infrastructure de géodate la télédétection par satellite est une source d'information importante. Cette conclusion est supportée par les resultates encourageantes de l'étude présente dans cette article. L'objective de l'étude était d'évaluer les possibilités des images satellites nouvelles et de présenter l'information obtenue d'une façon accessible pour une grande communauté de planificateurs. Avec cette objective le concept du Carte Thématique par Satellite est élabore et appligué pour une zone rurale au Pays-Bas. 1 INTRODUCTION With The launch of Landsat-4 in june 1982 a new era of satellite remote sensing started. On board of this satellite a new sensor system was installed, the Thematic Mapper (TM) next to the conventional Multi Spectral Scanner (MSS) sensor system increasing the spatial resolution of 80m*80m to 30m- v 30m. Recently on february 22, 1986 the French/Swedish SPOT-1 (Systeme Probatoire d'Observation de la Terre) remote sensing satellite was launched increasing the spatial resolution to lOnAlOm. This development required an evaluation of the possibilities for application of this new information stream in planning and management of the land and water resources in the Netherlands. Use was made of Thematic Mapper imagery because at the time the study was carried out SPOT-1 was not launched. Future research will concentrate on the evaluation of SPOT imagery and on the comparison of Thematic Mapper with SPOT imagery. 2 OBJECTIVES Before the launch of Landsat-4 with onboard the Thematic Mapper sensor system the use of satellite remote sensing for land applications in the Netherlands were very limited. This was caused by the restricted spatial resolution of the conventional sensor systems in use of which the Multi Spectral Scanner (MSS) onboard the Landsat series of satellites with 80m*80m is best known. This situation is expected to change with the use of the high resolution sensors. The higher resolution meets more closely the detail of information needed in planning and management in the Netherlands. DHV Consulting Engineers carried out a case study to evaluate these possibilities of the new imagery and to establish the contribution which can be made to the already existing well-developed information structure present in the Netherlands. A second objective of the study became to develop a method to present the satellite information in a way accessible to a large community of planners, who are not acquainted to the use of remote sensing data. 3 METHODS For the project use was made of Thematic Mapper imagery of august 22, 1984 and january 23, 1983 of an area in the central part of the Netherlands, the "Kromme Rijn" Area. This region was chosen since it contains different land use types, small sized (<1.0 ha) agricultural fields and many small-scaled landscape elements. The project was carried out in two phases; the first phase was a qualitative evaluation of the thematic content of the imagery, the second phase concerned a more quantitative approach towards the preparation of the thematic content in the imagery onto a map. This lead to the development of the "Satellite Thematic Map". The imagery was processed on the RESEDA image processing system (DIPIX) of the National Aerial and Space Laboratory, NLR, The Netherlands. Contact prints for further analysis were made of false color and especially 4,5,3 channel combination composites. During the second phase as a test experiment a thematic map was prepared on which the land use changes were given in comparing to the most recent topographical map of that area. The topographical map used was of 1985 but based on aerial photography of 1980. Therefore land use changes in a 4 year period were presented on the thematic map. 3.1 Sensor characteristics Characteristics of the Landsat Thematic Mapper and Spot system are presentend in table 1. The sensors onboard the SPOT-1 satellite record in two different modes; one 10m*10m spatial resolution panchromatic mode and a multispectral mode with a 20m*20m spatial resolution. A new feature of SPOT is its off-nadir
