géoréférencées

Géoréférencées is a French term that translates to "georeferenced" in English. It describes data or objects that have been assigned a specific geographic location. This location is typically defined using a coordinate system, such as latitude and longitude or a projected coordinate system like UTM. In essence, georeferencing links a piece of information to a point on the Earth's surface.

The process of georeferencing is fundamental in Geographic Information Systems (GIS) and spatial analysis. It allows for the accurate mapping and analysis of diverse datasets, from satellite imagery and aerial photographs to cadastral maps and cadastral plans. When a map or image is georeferenced, its pixels or features are aligned with real-world coordinates, enabling it to be overlaid and analyzed with other geographically referenced data.

Common applications of georeferenced data include environmental monitoring, urban planning, resource management, and emergency response. By understanding the spatial relationships between different entities, decision-makers can gain valuable insights and make more informed choices. The accuracy and precision of georeferencing are crucial for the reliability of any subsequent spatial analysis.
