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

Integrated Geographical 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 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) – georefferencial database with specified scale and additional data for visualization in traditional form NMA LITHUANIA

Levels 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 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 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 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, Florence1998 Award Special Achievement in GIS at World ESRI User Conference, San Diego1999 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 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 NMA LITHUANIA

Statistics Lithuania GIS in Statistics Lithuania GIS subdivision Regional breakdown GDB Codification Dissemination of Census results STATISTICS LITHUANIA

GIS in Statistics Lithuania GIS subdivision to Population Census Division was established on 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.

STATISTICS LITHUANIA GIS in Statistics Lithuania Regional breakdown: The territory of Lithuania is divided into following regional levels: Counties (10) Municipalities (60) Seniunija (462) - smallest local administrative unit

STATISTICS LITHUANIA GIS in Statistics Lithuania 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

STATISTICS LITHUANIA Point map of one city of Lithuania. There georefferencial background is linked with address data bases and register data bases. Those data basis is linked through UAK (unique address code). GIS in Statistics Lithuania

STATISTIC LITHUANIA Address point UAK Georefferencial background

STATISTICS LITHUANIA GIS in Statistics Lithuania Codification: Geographical objects are coded according InGIS standard. All geographical objects are divided into themes according criteria.

STATISTICS LITHUANIA GIS in Statistics Lithuania Structure of geo - code: - 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

Dissemination of Census results: Statistical publications CD Internet STATISTIC LITHUANIA GIS in Statistics Lithuania

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.
