Vegetation health can be monitored using a time series of remotely sensed images by calculating the Normalized Difference Vegetation Index (NDVI). We assessed temporal trends throughout an NDVI time series with three sensors: Advanced Very High Resolution Radiometer (AVHRR), the Moderate Resolution Imaging Spectroradiometer (MODIS) and Landsat Thematic Mapper/Enhanced Thematic Mapper Plus (TM/E...

Effective May 5, 2003, Landsat-5 (L5) Thematic Mapper (TM) data processed and distributed by the U.S. Geological Survey (USGS) Earth Resources Observation System (EROS) Data Center (EDC) will be radiometrically calibrated using a new procedure and revised calibration parameters. This change will improve absolute calibration accuracy, consistency over time, and consistency with Landsat-7 (L7) En...

This study examines the need/importance for ground validation of Landsat 5 Thematic Mapper (TM) and 7 Enhanced Plus (ETM+) observation at 2 gas flaring sites in Rivers State Niger Delta, Nigeria. 12 imageries (3 TM 9 ETM+) acquired from 25/03/1987 to 08/03/2013 with < % cloud contamination were used. Both are located within a single scene (Path 188, Row 057). Fieldwork measurements obser...

Comprehensive investigations on the between-sensor comparability among Landsat sensors have been relatively limited compared with increasing use of multi-temporal records in time series analyses. More seriously, sensor-related difference has not always considered applications. Accordingly, comparisons were conducted all available currently, including Multispectral Scanner (MSS), Thematic Mapper...
