Cabinet of Ministers Regulations No. 88 in Riga 2008. on 11 February (pr. 8. § 3) national geodetic network classification issued under the State statistics law 7.1 article 1. determines the national geodetic network classifier. 2. the national geodetic network classifier's objective is to provide the national geodetic network points according to the type of GEODESIC and GEODESIC point class identification. 3. the national geodetic network classifier determines the national geodetic network points corresponding GEODESIC and GEODESIC point class codes (annex) as follows: 3.1 the GEODESIC form is determined by the code letters;
3.2. the GEODESIC point class determines the code digit. 4. Global Positioning network of permanent stations and astronomical, GEODESIC points class. Prime Minister Godmanis I Defense Minister V.
