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.
