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

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

NMALITHUANIA

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

NMALITHUANIA

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

Data collectionData collection

• Aerial photography and satellite images

• Additional data from 20 organizations (including NSI)

• Photogrammetry: scanning, analytical plotters, digital photogrammetric workstations

• Cartographic workstations using Intergraph and ESRI software

Database driven cartographyDatabase driven cartography

• Production of GIS-oriented cartographic data

• Based on ESRI compatible software

• ArcInfo™, ArcView™, GeoVektra in use, PLTS in implementation

• Best technical solution at European ESRI User Conference, Florence’1998

• Award “Special Achievement in GIS” at World ESRI User Conference, San Diego’1999

GIS subdivision to Population Census Division was established on 2001 09 01.

Main tasks:•Preparation of thematic maps of Census and statistical data on different levels of administrative units;•Analyses and dissemination of Census data and other statistical information using GIS tools;•Internet for dissemination statistical information (thematic maps);•Comparison of statistical data between countries using GIS tools.

Regional breakdown:

The territory of Lithuania is divided into followingregional levels:

Counties (10)

Municipalities (60)

Seniunija (462) - smallest local administrative unit

In our GDB there are boundaries of:

• Counties (NUTS 3)

•Municipalities (NUTS 4)

First task to update GDB :

•Seniunija (NUTS 5)

•Residential areas - urban and rural
