Background

A consortium of polar data coordinating bodies has recently hosted a number of useful workshops and events to foster collaboration between individuals, institutions, projects and organisations. These events have built on polar data coordination efforts including progress made during the International Polar Year, and two Polar Data Forum meetings.

More recently, the focus has been on identifying and understanding the specifics of polar data sharing and interoperability through workshops such as the Polar Connections Interoperability Workshop and Assessment Process hosted by the European Space Agency in 2016, and the Arctic Spatial Data Pilot implemented by the Open Geospatial Consortium. In May of 2018, the Polar Data Planning Summit (PDPS) hosted by the University of Colorado focused on specific interoperability priorities and the organizational and community-building aspects of data sharing and interoperability.

These and other polar activities have identified a need for continued, detailed technical collaboration in order to advance Polar Data Management. At PDPS technical discussions centred on achieving federated search through the exchange of standardised, well formatted discovery metadata. This is an important first step towards an interconnected polar data system and important gaps and mitigation have been identified at the levels of standardisation, exchange protocols, semantic annotation etc. Discussions also identified challenges consuming data from different sources and communities. Following the PDPS discussions continued during the Arctic Observing Summit (AOS) held in Davos in June of 2018, discussions on how to maintain momentum and facilitate the process towards an interconnected polar data management system resulted in the commitment by the community to a series of more technically oriented workshops focused on developing an architecture for this global system. This is a response to requests from PDPS and AOS participants to coordinate activities between communities. This initiative has been proposed as a deliverable for the upcoming Second Arctic Science Ministerial.

These activities have been and will continue to be organized by a group of coordination bodies including the IASC-SAON Arctic Data Committee, the Southern Ocean Observing System, Standing Committee on Antarctic Data Management, GEO Cold Regions Initiative, Polar View, Arctic Portal, ELOKA, Canadian Consortium on Arctic Data Interoperability, U.S. Inter-agency Arctic Research Policy Committee Arctic Data Sub-Team, and the host of this meeting, the WMO Global Cryosphere Watch. A complete list of organizing bodies is provided below.

The primary purpose of this workshop is to solidify the architecture development team and to continue progress on components already under development. Specifically, work undertaken by the polar data community on:

Federated Search for Polar Regions

ADC-IARPC-SCADM Vocabularies and Semantics Working Group

 

General Background on Status and Requirements of Polar Data Management

Registration / Transportation

Registration for in-person attendance is now closed. If you would like to participate remotely, please contact us using the contact information provided below.

Transportation

WMO is located next to station Geneva-Sechèron (this is NOT the main station Cornavin). From Geneva Airport (GVA) it takes a couple of minutes by taxi/uber, or around half an hour by either bus or train to get to WMO or the center of Geneva. More information on public transport is available on https://www.gva.ch/en/desktopdefault.aspx/tabid-67/. In the baggage hall of Geneva Airport are machines where you can get a free 80-minute ticket for public transport to get to your hotel. Several hotels provide free public transport cards to use during your stay in Geneva, otherwise, a single ticket is CHF 3.

Geneva is also well reachable by train from several directions allowing flights to other airports as well or full train rides to Geneva.

WMO, train stations and airport

Picture by WMO, go to their website for more information on specific lines of bus/tram to take to WMO

 

Bus Access to WMO:

Buses 1, 25, stop Jardin Botanique and 11, 28 (stops
Secheron or Jardin Botanique).
United Nations building is at about 500 m.

Accommodation

There are several hotels close to WMO, and many more around Cornavin station and in other parts of Geneva. Besides using public transport you can also walk from hotels in near Cornavin station to WMO, this takes around 20 minutes and it is a very nice walk along the lake.

Hotels close to WMO headquarters:

Or look at booking.com (direct link for Geneva, adjust dates to your own travel schedule) or any other booking site of your liking for hotels

Visa information
