It is the difference between looking at a globe with topology versus a map with a topographical legend. Google Maps is extremely helpful if you need directions somewhere, but if you are doing an in depth analysis on erosion of a desert based on water and wind patterns, you will find ...
The fine-resolution (3″ or finer) terrain data bases such as SRTM (Shuttle Radar Topographical Mission) or USGS's DEM (Digital Elevation Model) data are necessary. Moreover, since 3DWF is used to model the fine-scale (meters up to 100 m) atmospheric flow, it needs fine resolution ...
These slope angle and aspect maps were then compared with the annual NDSI image using the Map Algebra tool in ArcGIS 10.1. Furthermore, these were reclassified to estimate the nature of the relationship between SCA and topographical characteristics. 4.4. Spatial correlation between SCA and climate ...
