100 dating siters in swiss

The project Ellipse was finalized at the end of 2016 and the results are documented in the manual for the Archiving of Federal Geodata.

Embark on a voyage through time with swisstopo’s topographic maps and travel through almost 175 years of Swiss cartographical history, even as far back as the time before the Swiss Confederation was founded. When it comes to the sustainable management of our living space, historical maps and digital 3D models are just as important bases as geological, geophysical and geotechnical datasets.

Basic geological data in digital form are primarily used for carrying out modern geological analyses and exploring the underground.

Although the dating results allow to chronologically discern between glacial and interglacial periods, a finer resolution on a stadial/interstadial level cannot unfortunately be obtained by the current state-of-the-art methods of luminescence dating as applied in this study.

Archiving of geodata on the federal level focuses on the archival storage of geodata for an unlimited period of time.

The ages presented in this study suggest that the deposition of proglacial outwash deposits in the northern Alpine foreland associated with the penultimate glaciation is time equivalent with marine isotope stage (MIS) 6.

Furthermore, our results imply relatively rapid ice decay in late MIS 6 towards termination 2, which is consistent with previous studies dealing with the penultimate glaciation in the circum-alpine region.

The archived geodata should be made available in a future geo information system.

Within the project Ellipse, swisstopo and the Swiss Federal Archives (SFA) are developing a solution for the archiving of geodata.

Verbal communication in association with topographic objects is difficult to imagine without the use of names.

It is much easier to locate geographic units and elements with the aid of names than through the use of coordinates.

However, modern (local) reference systems, distinguish themselves by providing a precisely defined link to global systems, thus allowing absolute positioning within a centimetre.

In the field of engineering surveying, swisstopo provides a broad variety of services, ranging from the development of fundamental GNSS networks and the operation of permanent GNSS stations, through to the analysis of deformations in dams, gravity calculations and gyroscopic measurements.

The National Maps were implemented in varying scales up and subsequently replaced the Dufour and Siegfried maps and their supplements.
