EPSG:7004

Ellipsoid

Bessel 1841

Attributes

Unit: metre

Data source: OGP

Information source: US Army Map Service Technical Manual; 1943.

Revision date: 1999-04-22

Remarks: Original Bessel definition is a=3272077.14 and b=3261139.33 toise. This used a weighted mean of values from several authors but did not account for differences in the length of the various toise: the "Bessel toise" is therefore of uncertain length.
