GPS

A GPS (Global Positioning System) device is a satellite-based navigation tool used to determine accurate geographic locations by calculating coordinates such as X, Y, and Z values along with other spatial information. It works by receiving signals from multiple satellites and applying trilateration techniques to identify the exact position of a point on Earth. GPS technology provides real-time location data with high accuracy, making it an essential tool in GIS, surveying, mapping, and navigation.

In geospatial applications, GPS devices help professionals collect field data, record feature locations, validate spatial datasets, and create precise digital maps. They are widely used for land surveying, urban planning, transportation, agriculture, environmental monitoring, disaster management, and outdoor navigation. By delivering reliable positioning information, GPS devices improve the accuracy, efficiency, and quality of spatial data collection and analysis. Their ability to capture precise location details makes them a valuable component of modern geospatial workflows and location-based decision-making systems.
