SIRGAS is a non-profit organization whose main purposes are the definition, realization, and maintenance of the 3D geocentric reference system for the Americas, including a gravity field-related vertical reference system. Its initiatives are concentrated on a continuous improvement of its components to be consistent with the state-of-the-art in geodetic issues and to satisfy in a better way the user needs.
As a member of the Commission 1 (Reference Frames) of the International Association of Geodesy (IAG) and as a Working Group of the Cartographic Commission of the Pan-American Institute of Geography and History (PAIGH), SIRGAS provides the adequate support to develop and combine all scientific and practical activities related to precise geo-referencing and navigation, Earth sciences research, and multidisciplinary applications. In particular, SIRGAS furnishes the fundamental layer for the geospatial data infrastructure in the region. Consequently, SIRGAS permanently assists the Regional Committee of the United Nations on Global Geospatial Information Management for the Americas (UN-GGIM: Americas), whose main objective at present is to promote the UN Resolution on the Global Geodetic Reference Frame for Sustainable Development, adopted at the UN General Assembly on 26th of February, 2015.
The achievements of SIRGAS as a reference frame and as a technical community are possible thanks to the maintenance of an active network of people and organizations working in the same direction and contributing to the different SIRGAS objectives.
Recent achievements, on-going activities, and new challenges are presented and discussed in the SIRGAS Annual Symposia. In this opportunity, we have the kind invitation from the Universidad Nacional Pedro Henriquez Ureña (UNPHU) to hold the Symposium SIRGAS 2015 in Santo Domingo, Dominican Republic, from 18 to 20 November. In the days previous to the Symposium, from November 16 to 17, a new edition of the SIRGAS School on Reference Systems is scheduled. This School is oriented to invite the Caribbean countries to participate in the different SIRGAS activities developed in the region. The SIRGAS School is sponsored by the International Union of Geodesy and Geophysics (IUGG) through the project Monitoring crustal deformation and the ionosphere by GPS in the Caribbean, which is also supported by the IAG, the International Association of Seismology and Physics of the Earth's Interior(IASPEI) and the International Association of Geomagnetism and Aeronomy (IAGA).
