The grayscale image of band 1 provides increased penetration of water bodies while also differentiating soil and rock surfaces from vegetation, commonly used for detecting cultural features (Band Combinations).  The Band 1 image was downloaded from the ERTS Satellite of … Continue reading →

The visible Spectrum – Band 1 image was created through the ENVI Program by applying a RGB (visible) spectrum to the Band 1 Image downloaded through the ERTS Satellite of the Landsat Program. On the terrestrial land, the visible spectrum … Continue reading →

The 3-D – Visible Band 1 Image is created by linking the Visible Spectrum version of Band 1 with Elevation Data provided by the Shuttle Radar Topography Mission (SRTM) to create a 3-D Image of the Blue Band. The 3-D … Continue reading →

The Normalized Difference Vegetation Index (NDVI) data provides a numerical value to the relative amount of live green vegetation. Through the ENVI Program, we created the NDVI Image with bands 3 and 4 (Red and IR) from the ERTS Satellite … Continue reading →

The Nightlight Image was produced as a sub-set of the Global Defense Meteorological Satellite Program (DMSP) run by the National Oceanic and Atmospheric Administration. The image provides for an analysis of light pollution in the study area’s, with white areas … Continue reading →
