Law of Geodesy and Cartography Law of Geodesy and Cartography on the 28on the 28thth of June, 2001 of June, 2001

State geodetic network, topographic and special maps:– Geodetic network

– Aerial photography and satellite images

– Orthophoto production

– Topographic mapping in 1:10000-1:1000000 scales

– Georefferencial databases

Page 4: STATISTICS LITHUANIA Report on the use of GI in the NSI and NMA in Lithuania Vilius Zilevicius - Institute of Aerial Geodesy, Lithuania Margarita Malakauskiene

Municipalities– Mapping materials in 1:500-1:5000 scales

– Content of geodata bases

– Data for NMA for basic and special mapping

Ministries and state organizations (including NSI):– Participate in planning of state mapping, creation of GDB and updating

programs

– Thematic DB on the basis of georefferencial data

Integrated Geographical Integrated Geographical Information System (InGIS)Information System (InGIS)

• Defines principles and rules for creation, registration, standardization and administration of geodata

• Interconnects cadastres and registers which are based on georefferencial (cartographic) background

• Defines main principles for interaction of different (thematic) geodata bases created by various organisations

Cartographic DataBase (KDB)Cartographic DataBase (KDB)

• Practical realization of GIS is connected with specified scale, which determines content of database and positional accuracy

• Cartographic DataBase (KDB) – georefferencial database with specified scale and additional data for visualization in traditional form

Levels of KDBLevels of KDB

• Micro – hydrography, roads, railroads, place names, geodetic network – used with orthophoto backdrop

• Mini – some additional data – used with orthophoto backdrop

• Midi – standard topographic map according specification

• Maxi – additional thematic information

Geographic Information SystemsGeographic Information Systems

Based on two different co-ordinate systems:

– LKS94 – for large scale (1:500-1:20000) mapping. One zone for whole country, based on GRS80 ellipsoid, ETRS89 co-ordinate system, TM projection with scale coefficient 0.9998 and 24° central meridian

– UTM – for medium and small scale (1:25000-1:100000) mapping. Two zones for whole country, based on WGS84 ellipsoid, WGS84 co-ordinate system, UTM projection with scale coefficient 0.9996 and 21°, 27° central meridians
