DOI: 10.1191/0309133305pp432ra Satellite remote sensing of forest resources: three decades of research developmentResearch and Innovation, Ordnance Survey, Romsey Road, Southampton SO16 4GU, UK, Doreen.Boyd{at}ordnancesurvey.co.uk
Centre for Environmental Systems Research, School of Environment and Life Sciences, University of Salford, Manchester M5 4WT, UK Three decades have passed since the launch of the first international satellite sensor programme designed for monitoring Earths resources. Over this period, forest resources have come under increasing pressure, thus their management and use should be underpinned by information on their properties at a number of levels. This paper provides a comprehensive review of how satellite remote sensing has been used in forest resource assessment since the launch of the first Earth resources satellite sensor (ERTS) in 1972. The use of remote sensing in forest resource assessment provides three levels of information; namely (1) the spatial extent of forest cover, which can be used to assess the spatial dynamics of forest cover; (2) forest type and (3) biophysical and biochemical properties of forests. The assessment of forest information over time enables the comprehensive monitoring of forest resources. This paper provides a comprehensive review of how satellite remote sensing has been used to date and, building on these experiences, the future potential of satellite remote sensing of forest resources is highlighted.
