Remote sensing as a tool to visualize land use/-cover change and to support environmental education ― A case study in NRW (North Rhine-Westphalia, Germany) in context of the local Agenda 21 process

摘要

In this ongoing project the land use/-cover change of the last 25 years in North Rhine Westphalia is visualized via an Internet Portal. LANDSAT data of the years 1975, 1984 and 2001 are used with ancillary GIS data to derive twelve general land use/-cover categories for every time slice. Additionally at some areas of special interest the visualization of land use/-cover is supported by multisensoral data (ASTER, IKONOS, CORONA, ERS) and orthophotos to show the potential of remote sensing for environmental education.
