Spatial coincidence, proximity, surface analysis, dispersion, and least-cost path analysis are some common spatial analysis done with raster GIS data.
This article presents a summary of least cost path analysis, an important tool in GIS. Least cost path analysis is a distance analysis tool within GIS that uses the least cost path (the path between two locations that costs the least to those travelling along it) to determine the most cost-effective route between a source and destination. This article provides an overview of that topic as well as the requirements and steps for creating a least cost path analysis.
Heat mapping, from a geographic perspective, is a method of showing the geographic clustering of a phenomenon. Sometimes also referred as hot spot mapping, heat maps show locations of higher densities of geographic entities (although hot spot analysis tends to be used to show statistically significant patterns: more about the difference between heat […]
