Data standards

The data standards define the format, accuracy, quality and range of the information on the dynamic gene conservation units of forest trees that has been entered into the EUFGIS database by the national focal points. Climatic variables have been obtained automatically from the WorldClim database.

Datum

Indicate the Datum of the projection used to obtain the coordinates. If not provided ‘WGS 1984’ will be used.

A horizontal geodetic datum based on an ellipsoid that has its origin at the earth's center of mass. Examples are the World Geodetic System of 1984, the North American Datum of 1983, and the Geodetic Datum of Australia of 1994. The first uses the WGS84 ellipsoid; the latter two use

the GRS80 ellipsoid.
