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.
