GIS and Geospatial Technologies
Articles focusing on the application of geographic information systems (GIS), geospatial technologies, remote sensing, LiDAR, and Global Positioning System (GPS). These technologies serve as critical tools for understanding and interacting with our physical environment. GIS allows for the mapping and analysis of spatial data Geospatial technologies refer to the various tools used to measure and analyze Earth’s lands and resources. Remote sensing provides a way to collect data from a distance, often via satellites or high-flying aircraft, and is commonly used for environmental monitoring and military applications.

Overview of Fuzzy Logic Site Selection in GIS
Site selection is a type of GIS analysis that is used to determine the best site for something and fuzzy logic is one site selection method. It assigns membership values to locations that range from 0 to 1 and is commonly used to find ideal habitat for plants and animals. This article examines fuzzy logic and explains how and when to use it.
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.
