Report on the use of GI in the NSI and NMA in Estonia

This report examines the utilization of Geographic Information in the National Statistical Office and National Mapping Authority of Estonia. It explores data availability, mapping projects, spatial data models, and issues related to data collection and changes over time.

  1. Report on the use of GI in the NSI and NMA in Estonia Inge Nael (NSI) Kristian Teiter (NMA)

  2. NSI and NMA NSI- The Statistical Office of Estonia (SOE) NMA- Estonian Land Board (ELB)

  3. NMA is responsible for • Land reform • Cadastre– maintenance of the state base register about land parcels and property transactions • Cartography- coordination and implementation of nationalmapping programsand maintenance of spatial datasets • Geodesy –coordination of creation of the geodetic network and maintenance of geodetic database

  4. Data availability • Cadastral data are public • The use and price of digital topographic data are regulated by the corresponding procedure to be approved by the Minister of Environment.

  5. Mapping projects Estonian Basic Map – topographic digital database 1:10 000; Estonian Base Map – GI digital database 1:50 000; Estonian Soil Map – GI digital database 1:10 000; Maps of urban areas – topographic digital databases 1:2000; MapBSR - digital database 1:1000 000 produced in international co-operation between the states within the Baltic Sea catchment area; EuroGlobalMap – digital database 1:1000 000 for the whole of Europe produced under EuroGeographics conforming to GlobalMap specifications.

  6. Estonian Basic Map • The Estonian Basic Map is a seamless digital topographic database covering the whole territory of Estonia and which contains information on utilities (roads, electric power lines, etc.), settlement, hydrography, relief, place names and land use. • By the end of 2001, the digital mapping of 67% of Estonia´s territory will have been completed • The digital map covering the whole of Estonia is expected to be ready by the end of 2002.

  7. Models of Spatial Data and ENTD • The aim of the project is to create preconditions for maintaining spatial data of different state registers and databases in Estonia in the same system and allowing cross-reference between them • ENTD is the Land Board’s GIS-database that contains topographic data collected during basic mapping.

  8. Cadastral Information System • Data Registration (LAN-WAN application) • Public Services (WEB application) • Cadastral Unit (CU) information query for public user http://www.maaamet.ee/teenus/kiirp2ring.php • Service called “Land Information for Public” http://www.maaamet.ee/teenus/maainfo.php

  9. Data collection issues • Major providers of spatial data are private surveyors (cadastral data) and mapping companies (topographic data) • The collection of topographic data is mainly related to the Estonian Basic Map program and performed during mapping works

  10. Changes over time • The digital map covering the whole of Estonia is expected to be ready by the end of 2002 and data will be converted into ENTD. • This will enable the updating processes to be accelerated and the updating period to be shortened. • The policy of data updating will be changed.
