Image

An image is a digital representation of a scene, object, landscape, or geographic area captured using devices such as digital cameras, scanners, drones, aircraft, or satellites. It consists of thousands or millions of pixels, with each pixel storing information about color, brightness, or intensity at a specific location. In GIS and remote sensing, images are a fundamental source of spatial data used to visualize and analyze the Earth's surface. They help identify natural and human-made features, monitor environmental changes, and generate accurate maps. Geospatial images support a wide range of applications, including land use and land cover mapping, urban planning, agriculture, forestry, transportation, disaster management, and environmental monitoring. When processed with GIS and image analysis techniques, they enable feature extraction, change detection, terrain analysis, and object classification. Common types of geospatial images include satellite imagery, aerial photographs, drone imagery, and scanned maps, providing reliable and up-to-date information for spatial analysis and informed decision-making.
