Overview of Weighted Site Selection and Suitability Analysis

Site selection is a type of analysis used in GIS to determine the best place or site for something. Weighted site selection analysis is one type of site selection that allows users to rank raster cells and assign a relative importance value to each layer. This article examines weighted site selection by explaining how it works and when it should be used. It also provides an example of a weighted site selection project for reference.

Overview of Least Cost Path Analysis

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.

Overview of Flow Mapping

Flow maps are a type of map used in cartography to show the movement of objects between different areas on the Earth’s surface. This article provides a basic overview these maps, a description of how they work, describes the three different types of flow maps and explains the characteristics of a good flow map. For reference, it also several examples of different types of flow maps.
