Remote sensing and the monitoring of ecosystems
Remote sensing techniques offer unique opportunities to collect measurements on ecosystem parameters. The scales at which observations are made present new dimensions in ecological analysis. The paper reviews significant progress in the field with particular attention to vegetation monitoring at regional to global scales. The current capabilities to estimate ecosystem structure, composition, primary productivity and evapotranspiration are described. The monitoring of fire and biomass burning is also presented as a significant achievement in the application of remote sensing techniques. A short review of the existing instrumentation pinpoints the capabilities and limitations of the available technology. Finally, it is argued that the slow progress in the application of remote sensing techniques to ecological analysis is partly due to an excessive technology push and partly to the limited interest of ecologists.
