Article 32Article 32

Spatial reference system for Republic of Serbia is terrestrially three dimensionalcoordinate system that under the definition of coordinate beginning, orientation ofcoordinate axis, ratio, length unit and time evolution, coincides with Europeanterrestrialreferencesystem– EuropeanTerrestrialReferenceSystem1989, (furtherterrestrialreferencesystem– EuropeanTerrestrialReferenceSystem1989, (furtheron as: ETRS89).

For the first time AGROS was also defined explicitly by a Law act together withintroducing of a new system. In the section of Law defining the concepts AGROS isdefined as follows:“AGROS” presents the Network of permanent stations of globalpositioning system for the territory of Republic of Serbia.

Article 38, paragraph 2

While in the section of Law defining the realization of the new Spatial referencesystem AGROS is introduced through the article 38, paragraph 2 that says:Spatialand horizontal reference systems in paragraph 1 of this article are defined by theReference network of Republic of Serbia – SREF and by the Network of permanentstations of Republic of Serbia – AGROS.

RGA as provider of fundamental spatial data has the key role in implementation of the infrastructure of spatial data at the national level in accordance with the current European initiatives

Draft Strategy for Establishment of the NSDI for the period 2010 – 2012

Metadata standard is defined, based on INSPIRE and ISO 19115 standards

Metadata editor was developed for supporting the set metadata standard and to facilitate collection and maintenance of the metadata

The initial geoportal ’geoSrbija’ as a tool for viewing and share distributed spatial data and services under the umbrella of the NSDI became operational in November 2009 [www.geosrbija.rs]

NSDI Council was established by the Serbian Government

RGA is president of NSDI council
