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 110000-11000000 scales
• Georefferencial databases

4
NMA LITHUANIA

• Municipalities
• Mapping materials in 1500-15000 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

5
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

6
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

7
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

8
NMA LITHUANIA
Geographic Information Systems

• Based on two different co-ordinate systems
• LKS94 for large scale (1500-120000) 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
  (125000-1100000) 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

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

10
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
