EUREF Products

The EUREF organization generates a set of products mainly to be used in geodesy but certainly also suitable for other tasks in the geo-referencing branch. This website holds a compilation of information about the products from EUREF projects and services.

Product classification: A terminology was setup to classify the various EUREF products. It consists of the important characteristics and of the potential quantities. It may help users to identify products they are interested in.
