Georeferreerde

Georeferreerde is a Dutch term that translates to "georeferenced" in English. It describes data that has been assigned a geographic location. This means that each point, feature, or area within the dataset is associated with a specific coordinate on the Earth's surface. Georeferencing is a fundamental process in Geographic Information Systems (GIS) and spatial analysis.

The process of georeferencing typically involves transforming data from an unknown coordinate system into a known, standardized one. This can be done by linking the data to existing map coordinates or by using known control points. For example, an old scanned map without digital coordinates can be georeferenced by aligning it with a modern, accurate digital map using common points like road intersections or prominent landmarks.

Georeferenced data allows for spatial queries, analysis, and visualization. It enables users to overlay different datasets, measure distances and areas, and understand the spatial relationships between various geographic elements. Common examples of georeferenced data include satellite imagery, aerial photographs, scanned maps, and survey data. The ability to precisely locate information on the Earth's surface is crucial for applications ranging from urban planning and environmental monitoring to navigation and disaster management.
