Georeferáltság

Georeferáltság refers to the characteristic of data being associated with a specific location on Earth. This association is typically achieved by assigning geographic coordinates, such as latitude and longitude, or other spatial referencing systems to the data. In essence, it means that the data has a defined position within a geographic space.

This concept is fundamental in fields like geographic information systems (GIS), remote sensing, surveying, and cartography. When data is georeferenced, it can be accurately plotted on maps, analyzed in relation to other spatial information, and used for spatial queries and modeling. For example, satellite imagery is georeferenced so that each pixel can be precisely located on the ground. Similarly, the location of a building or a property boundary is georeferenced to appear correctly on a map and to be integrated with other spatial datasets.

The process of georeferencing involves transforming data from an arbitrary coordinate system into a standard geographic coordinate system, like WGS 84. This transformation often requires control points, which are identifiable features that have known coordinates in both the source and target coordinate systems. Without georeferáltság, raw data, no matter how detailed, lacks the crucial spatial context necessary for many practical applications.
