Flood Hazard Mapping using Aster Image data with GIS
Flood is one of the most devastating natural hazards which lead to the loss of lives, properties and resources. It has therefore become important to create easily read, rapidly accessible flood hazard map, which will prioritize the mitigation effects. This study addresses the need for an efficient and cost-effective methodology for preparing flood hazard maps in Ghana, particularly those region...
متن کاملComparing Aster and Landsat 7 Etm+ for Change Detection
The limited radiometric resolution and expiring life expectancy of the Landsat sensors have prompted this study to investigate the potential of using ASTER imagery in conjunction with Landsat imagery. This project developed methods to calibrate processed ASTER imagery and Landsat 7 ETM+ imagery to equivalent measurements for change detection studies. Landsat 7 ETM+ and ASTER imagery of southwes...
متن کاملDrought Effects on Vegetation Changes in Kashkan Basin of Lorestan Using ETM + and OLI Landsat Data
Background and objectives: Vegetation is one of the most important elements of an ecosystem, which is directly related to the moisture conditions of the land. Estimation of plant drought indices such as VCI, TCI, VHI is an effective tool to assess the effects of drought by calculating NDVI. In this regard, several studies have been conducted that explain how to calculate and use these indicator...
متن کاملIntegration of Lidar and Landsat Etm+ Data
Lidar data provide accurate measurements of forest canopy structure in the vertical plane however current lidar sensors have limited coverage in the horizontal plane. Landsat data provide extensive coverage of generalized forest structural classes in the horizontal plane but are relatively insensitive to variation in forest canopy height. It would therefore be desirable to integrate lidar and L...
متن کاملComparison of Radiometric Normalization Methods on Landsat Etm+ and Aster Data
Change detection techniques are widely diffused to derive basic information in the analysis of land cover transformations. Some difficulties in multi-date imagery treatment persist in remote sensing applications because of errors due to noise, to environmental conditions and to geometric and radiometric distortions introduced during the acquisition or transmission phases of satellite systems. S...
