A Comparison of Change Detection Methods in an Urban Environment Using LANDSAT TM and ETM+ Satellite Imagery: A Multi-Temporal, Multi-Spectral Analysis of Gwinnett County, GA 1991-2000

Paul DiGirolamo
Ground truthing and accuracy assessment determined that land cover change detection using the NDVI and Tasseled Cap image transformation methods performed best in the study area, while PCA performed the  ...  Using Landsat 5 Thematic Mapper (1991) and Landsat 7 ETM+ (2000) imagery of Gwinnett County, GA, change images were obtained using image differencing of Normalized Difference Vegetation Index (NDVI), principal  ...  I would also like to acknowledge all of the other talented teachers and professionals at Georgia State University that helped me to complete my program of study including Dr. John Allensworth, Dr.  ...

Those were directly derived from Landsat MSS, TM, and ETM remote sensing images for the growing season months for the years of 1973, 1990, 1991, 2002 and 2005.  ...  In general, land degradation in the study area increased from 1990 to 2005, and 94% of the area is considered to be degraded to varying degrees.  ...  They used multitemporal Landsat TM images to give hints on the origin, extent, and intensity of degradation through sand accumulation, which enabled them to derive trends in sand movements.  ...
