1 Report on the use of GI in the NSI and NMA in Lithuania
STATISTICS LITHUANIA NMA LITHUANIA Report on the use of GI in the NSI and NMA in Lithuania Vilius Zilevicius - Institute of Aerial Geodesy, Lithuania Raminta Adamonyte - Statistics Lithuania Workshop on GI/GIS matters for PHARE Countries

2 Law of Geodesy and Cartography on the 28th of June, 2001
NMA LITHUANIA Law of Geodesy and Cartography on the 28th of June, 2001 State geodetic network, topographic and special maps: Geodetic network Aerial photography and satellite images Orthophoto production Topographic mapping in 1: : scales Georeferencial databases

3 Ministries and state organizations (including NSI):
NMA LITHUANIA 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 programmes Thematic DB on the basis of georeferencial data

4 Integrated Geographical Information System (InGIS)
NMA LITHUANIA Integrated Geographical Information System (InGIS) Defines principles and rules for creation, registration, standartisation and administration of geodata Interconnects cadastres and registres which are based on georeferenced (cartographic) background Defines main principles for interaction of different (thematic) geodata bases created by various organisations

5 Cartographic DataBase (KDB)
NMA LITHUANIA Cartographic DataBase (KDB) Practical realization of GIS is connected with specified scale, which determines content of database and positional accuracy Cartographic DataBase (KDB) – georeferencial database with specified scale and additional data for visualization in traditional form

6 NMA LITHUANIA Levels of KDB Mikro – 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 Maksi – additional thematic information

7 Geographic Information Systems
NMA LITHUANIA Geographic 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 and 24° central meridian UTM – for medium and small scale (1: :100000) mapping. Two zones for whole country, based on WGS84 ellipsoid, WGS84 co-ordinate system, UTM projection with scale coefficient and 21°, 27° central meridians

8 Data collection Aerial photography and satellite images
NMA LITHUANIA Data 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

9 Database driven cartography
NMA LITHUANIA Database 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

10 Main products and projects
NMA LITHUANIA Main products and projects MapBSR – 1: scale database for Baltic Sea Region SABE – Seamless Administrative Boundaries of Europe GDB200 – 1: scale GIS database LTDBK50000-V – 1:50000 scale vector database derived from satellite imagery KDB10LT – 1:10000 scale cartographic database with different levels of data complexity ORT10LT – digital orthophoto with 0.5m resolution

11 Data updating and quality
NMA LITHUANIA Data updating and quality Working groups of EuroGeographics (former CERCO/MEGRIN): on Data Maintenance (former Updating) and on Quality Updating for 1:10000 scale base map data – 10 years period or on demand Preparations for ISO 9000 certification

12 STATISTICS LITHUANIA Regional breakdown: The territory of Lithuania is divided into 3 regional levels: NUTS 3 - Counties (10) NUTS 4 - Municipalities (60) NUTS 5 - Seniunija (462) - smallest local administrative unit

13 Codification Attribute data are coded according InGIS standard.
STATISTICS LITHUANIA Codification Attribute data are coded according InGIS standard. All geographical objects are divided into themes according criteria.

14 Codification Structure of geocode: - Code of theme
STATISTICS LITHUANIA Codification Structure of geocode: - Code of theme - Object number in the theme For example: administrative boundaries of counties as 02 code of theme number of object in this theme

15 GIS in Statistics Lithuania
GIS subdivision to Population Census Division was established on Main tasks: Analyses and dissemination of Census data and other statistical information using GIS tools; Preparation of thematic maps of Census and statistical data on different levels of administrative units; Internet for dissemination statistical information (thematic maps); Comparison of statistical data between countries using GIS tools.

16 GIS in Statistics Lithuania
Software: ArcView 3.1 and ArcView 3.2 for Windows ArcPress for ArcView ArcView Network Analyst for Windows Spatial Analyst for Windows NT ARCINFO and ArcPress NT ARCINFO Network MO Internet Map Server

17 GIS in Statistics Lithuania
In our GDB there are boundaries of: Counties Municipalities First task to update our GDB : Seniunija - smallest local administrative unit Residential areas - urban and rural

18 GIS in Statistics Lithuania
Point map of one city of Lithuania . There georeferencial foundation is linked with address data bases and register data bases. Those data basis is linked through UAK (unique address code).

19 Georeferencial background
STATISTIC LITHUANIA Georeferencial background Address point UAK X Y UAK

20 Dissemination of Census results
STATISTIC LITHUANIA Dissemination of Census results Statistical publications CD Internet

21 Dissemination of Census results
STATISTIC LITHUANIA Dissemination of Census results Statistical publications, Yearbook, CD Census data will be presented on thematic maps Internet Following 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.
