For spatial decision support and regional (agro-)ecosystem modeling, land use data are of central importance and have to be available in a spatial data infrastructure for regional modeling. Usually, land use data are available, but they lack the desired information detail for many purposes. For example, in official land use maps, agricultural land use is generally differentiated between arable ...

The history of remote sensing and development of different sensors for environmental and natural resources mapping and data acquisition is reviewed and reported. Application examples in urban studies, hydrological modeling such as land-cover and floodplain mapping, fractional vegetation cover and impervious surface area mapping, surface energy flux and micro-topography correlation studies is di...

bling the input data may be a formidable task. Developing a user interface that incorporates these tools has As knowledge of crop growth and development is quantified, it been recognized as an essential step toward increasing can be included in the computer code of crop simulators that mimic the essential features of plant–soil–atmosphere–management interacthe utility of crop simulators and dec...
