Due to the objectives that SIRGAS carries out through its Working Group III to contribute to the development of regional geodesy, two technical guides on the International Heights Reference Frame (IHRF) have been published. The first document developed by the Working Group III is called “Guidelines for IHRF station selection” and describes requirements and recommendations […]

In October 2002, the SIRGAS Directing Council decided the implementation of a web page summarising the main characteristics of SIRGAS. The design, maintenance and update of the SIRGAS web page was defined as a responsibility of the SIRGAS President and Vice-president. The first version of the SIRGAS web page was hosted by the Instituto Brasileiro […]
