Developing A Forest Growth Monitoring Model Using Thematic Mappery Imagery

TL;DRAbstract

Abstrract Recently most investigations in satellite-based remotely sensed data has concentrated upon the biophysical characteristics of vegetation for large area, little attention has been given to the allometric relationship of tree and reflectance to the recorded pixel value. In this research crown width and/or canopy closure was associated with pixel value in terms of their surface-exposure to satellite sensors. Given the fact that planted-tree crown closure is correlated with their height and diameter at breast height (dbh) in early stages of the plantations, it is expected that a relationship exists between tree canopy closure, height, dbh and their associated reflectance-values. The proposed concept was tested in a case study for planted black spruce (Picea mariana) using Landsat Thematic Mapper (TM). Crown width, height, and dbh of planted trees were measured in an area of 30m X 30m, for every 2-year age intervals, from 0 to 21 years. Canopy closure, mean height, and dbh of each
