Abstract
Advancement in spatial data processing especially using GIS techniques has been playing an important role in different applications. Multiple source spatial and non-spatial data can be processed for the analysis of spatiotemporal conditions of a given area. Having such an approach in mind the Bilate Watershed Biomass is analysed using multi-temporal Landsat images acquired in 1973, 1986 and 2001. Such data are processesed using digital image processing techniques including NDVI and Tasselled Cap analysis. Besides, different vector data are extracted from the images as well as other topographic and thematic maps. Land use land cover of the watershed is interpreted and based on that the level of biomass degradation is analysed. Using the integrated spatial information, decision support system has been applied for the identification of priority areas to be conserved due to their sever damage. The study identified major causes and effects of biomass degradation of the watershed.
