Historische Landesvermessung / Historical land survey

            Bis 1884 verlief der Nullmeridian durch das westliche Ende der Kanaren-Insel El Hierro, vormals auch als Ferro bezeichnet. Erst 1884 konnten sich die Engländer auf einer internationalen Konferenz durchsetzen, seither wird als Nullmeridian der Standort der Sternwarte in Greenwich bei London definiert. Im Jahr 1855, als die Tiroler Landesvermessung begann, war es also Standard, die Koordinaten mit Bezugspunkt El Hierro anzugeben. /

Until 1884, the prime meridian ran through the western end of the Canary Island of El Hierro, formerly known as Ferro. It was not until 1884 that the British were able to assert themselves at an international conference, and since then the prime meridian has been defined as the location of the observatory in Greenwich near London. In 1855, when the Tyrolean land survey began, it was therefore standard to specify the coordinates with the reference point El Hierro.
