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
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
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
STATISTICSLITHUANIA

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

Codification:
Geographical objects are coded according InGIS standard.
All geographical objects are divided into themes according criteria.

Structure of geo - code:
- Code of theme- Object number in the theme
For example: administrative boundaries of counties as 02

• Statistical publications, Yearbook, CD Census data will be presented on thematic maps
• InternetFollowing data will be presented:
Hydrology, roads, geographical names, administrative units.Population, population by age group, sex, education, etc.
It will be possible to work with the information of Internet:zoom in, zoom out, push and pick out objects, to choose the colors of the map according to needed classification.
