Estimating forest productivity in southern Illinois using Landsat thematic mapper data and geographic information system analysis techniques
Ecological researchers have recently begun to explore the potential of remote sensing in addressing questions about the structural and functional properties of ecosystems. The objective of our research is to analyze the relationship of Landsat Thematic Mapper (TM) data and field-collected measurements of forest productivity in southern Illinois. In addition to TM data, such site characteristics as slope angle and position, soil productivity indexes, and sun radiance factors were incorporated in the analysis. Techniques for using image and geographic information system data in relation to productivity measurements taken in the field are discussed. Correlation and multiple regression results revealed the importance of TM band ratios 7:4 and 2:1 and of the woodland productivity indexes of soils in predicting forest productivity. Directions for further research in this area are suggested.
