Image

An image is a digital representation of a scene, object, landscape, or geographic area captured using imaging devices such as digital cameras, scanners, drones, aerial sensors, or satellites. It records visual information in the form of pixels, where each pixel contains data representing the color, brightness, or intensity of a specific location. In geospatial applications, images serve as a critical source of spatial information, enabling users to observe, analyze, and interpret features on the Earth's surface with high precision. They play a vital role in mapping, land use and land cover analysis, environmental monitoring, urban and regional planning, precision agriculture, forestry, transportation, and disaster management. Images can also be processed using Geographic Information Systems (GIS) and remote sensing techniques to extract valuable insights, detect changes over time, and support informed decision-making. Common examples include satellite imagery, aerial photographs, drone-captured images, and scanned maps, all of which provide accurate and up-to-date visual data for spatial analysis.
