40962-MJP, Update of the Official Horizontal Geodetic Reference System for Costa Rica, declares in Article 1 that The official horizontal geodetic reference system for Costa Rica, called CR05, and its materialization through the National Geodetic Network, changes its acronym to CRSIRGAS as the official horizontal reference system for the Republic of Costa Rica, linked to the International Terrestrial Reference Frame ITRF2008 (IGb08) for the measurement epoch 2014.59, and henceforth, changes and updates thereto shall be governed by the new ITRF definitions implemented in the continental network of the Geocentric Reference System for the Americas (SIRGAS) called SIRGAS-CON, while Article 2 provides that The CRTM05 cartographic projection system shall remain the official projection for the cartographic representation of the continental national territory, extended for purposes of applying this cartographic projection to the baseline of the territorial sea in the Pacific Ocean and the Caribbean Sea, this line being defined in accordance with Articles 5, 6, and 7 of the United Nations Convention on the Law of the Sea, as the starting point for calculating the maximum breadth of all jurisdictional marine areas of the Costa Rican State.
Furthermore, Article 12 of the aforementioned decree reinforces the application of the CRTM05 cartographic projection as the official national coordinate system to which all work in the continental territory of our country must be referenced, by stating that The CRSIRGAS horizontal reference system and its associated cartographic projection CRTM05 for the continental territory, extended to the baseline of the territorial sea, and the "Universal Transverse Mercator" (UTM) cartographic projection, zones 16 and 17 for the jurisdictional marine and insular areas in the Pacific Ocean and the Caribbean Sea, shall constitute the sole official coordinate system for the Republic of Costa Rica, based on which all cartographic and geodetic surveys and activities carried out in the national territory by any public agency, person, or private entity, national or foreign, undertaking or contracting geodetic and cartographic work must be referenced, thereby helping to avoid public spending and, on the other hand, obtaining reliable, uniform, and comparable geographic information that is generally useful and supports decision-making at the various levels of the State.
