Application of Remote Sensing and Geographical Information System For Land Use / Land Cover Mapping And Change Detection in the Rural Urban Fringe Area of Enschede City, The Netherlands

摘要

Management and planning of urban space requires spatially accurate and timely information on land use and changing pattern. Monitoring provides the planners and decision-makers with required information about the current state of development and the nature of changes that have occurred.Remote sensing and Geographical Information system (GIS) provides vital tools which can be applied in the analysis at the district and as well, as the city level. Remote sensing becomes useful because it provides synoptic view and multi- temporal Land uses / Land cover data that are often required. Though often used only for identifying objects. This study evaluates the effectiveness of High-Resolution satellite data and computer aided GIS techniques in assessing the land use change dynamics with in the study area designated Enschede City, from 1993 to 1998. The methodology adopted involved the Visual interpretation of land use on acetate overlays according to the land use classification. Satellite images were used for the year 1993 and 1996 at scale 1:25000. A minimum delineation unit of 5 mm X 5 mm was used for mapping. Data was then digitised using ILWIS, the by creating a digital database for further analysis. Subsequently land use maps were crossed with each other to identify and quantify the land use changes types. Finally, Hot links and User Interface was developed so that the information can be provided to the user with a well-documented procedure. The system in this case will be operated from Arc / View environment.
