Geocache Description:

Projecto VG - Bicha (Serra de Montejunto) – PGS-02


A Rede Geodésica Nacional

A Rede Geodésica Nacional (RGN) é composta por um conjunto de pontos coordenados - Vértices Geodésicos - que possibilitam a referenciação espacial.


O número de vértices existentes na totalidade do território (Portugal Continental e Regiões Autónomas) é, actualmente, de cerca de nove mil, repartidos por vértices de:

Continente: 1ª Ordem (cerca de 120), 2ª Ordem (cerca de 900) e 3ª Ordem (com uma densidade aproximada de 1 vértice por cada 10 km²) Arquipélago dos Açores: cerca de 500 Arquipélago da Madeira: cerca de 150

A RGN é a infra-estrutura básica onde se apoia toda a cartografia do País, e que serve todos aqueles (empresas, autarquias e outros organismos públicos e privados) que, por força das suas actividades, necessitam de referenciar geograficamente os seus projectos (os Planos Directores Municipais, por exemplo).

The National Geodesic Network

The National Geodesic Network (RGN) is composed by a set of coordinate points - Geodesic Vertexes - that make spatial referencing possible.


The number of existing vertexes on the whole territory (Continental Portugal and Autonomous Regions) is, currently, of about nine thousand, and they are distributed in vertexes of: Continent: 1st Order (about 120), 2nd Order (about 900) and 3rdOrder (with an approximate density of 1 vertex per 10 km²); Archipelago of Azores: about 500; Archipelago of Madeira: about 150.

The RGN is the basic infrastructure that supports all the cartography of the Country, and that it serves all those (public and private companies, autarchies and other organisms) that, because of their activities, need to reference their projects geographically (the Municipal Director Plans, for example).
