Feldverifikation

Feldverifikation is a German term that translates to "field verification" or "ground truthing" in English. It refers to the process of confirming or validating information that has been collected or generated through remote sensing, mapping, or other data acquisition methods, by directly observing or measuring it in the actual location or "field" where it exists. This on-site inspection is crucial for ensuring the accuracy and reliability of the data.

The primary purpose of Feldverifikation is to reduce uncertainty and errors in datasets. For example, if a satellite image suggests the presence of a particular crop in a specific area, Feldverifikation would involve sending personnel to that location to visually confirm the crop type, its growth stage, and its extent. Similarly, in urban planning, proposed infrastructure developments might be subject to Feldverifikation to assess their real-world feasibility and potential impact on the surrounding environment and community.

This process is fundamental in various disciplines, including remote sensing, geographic information systems (GIS), agriculture, environmental monitoring, geology, archaeology, and urban planning. The data gathered during Feldverifikation can be used to calibrate sensors, correct misclassifications, update existing maps, and validate models. It provides essential ground truth that is otherwise unavailable from remote observations alone, thereby enhancing the practical utility and scientific rigor of spatial data.
