• INTRODUCTION
• - Production of the National Official Geodata
  Mapping Products (extreme alternatives)
• - National wide mapping and geodata production
  (mapping products) like strict obligation
• of the responsible govermental administration
  body, organizations or institutions
• financed completely by the government (state
  budget) with geodata kept as a state secret
• (restricted usage)
• - National wide mapping and geodata production
  left completely to the market and
• private enterprises where
  government is just one of customers on the market
  in
• accordance to the present
  and/or future needs.
• The State Geodetic Administration (SGA) of the
  Republic of Croatia (responsible national
• mapping organization) strategic guidelines and
  decisions
• - SGA will not build up its own production
  facilities for any kind of practical work
• or geodata production including
  national wide mapping
• - SGA will completely outsource production of
  the national official geodata
• (mapping products) to private
  sector (licensed private companies)

• FUNCTIONS AND RESPONSABILITIES
• State Geodetic Administration SGA
• - Definition of national official geodata
  products (for example topographic data,
• topographic maps, orthophoto maps, etc.),
  product specifications, standards,
• norms, etc.
• - Production planning (several years and year
  programs) - quantity and dynamics
• in accordance to state and user needs
• - Providing the funds for production (state
  budget, counties, cities, national public
• systems, etc.)
• - Product distribution to the users pricing
  policy
• - Products maintanance, etc.
• Licensed private companies (for performing the
  state survey and real estate works)
• - Production, following recent technology
  changes and transition from analog to
• digital tehnology
• - Quality of products (in accordance with
  product specifications)
• Croatian Geodetic Institute CGI

• CGI - QUALITY CONTROL SYSTEM
• Basis of the CGI QC System Set of
  documentation, specifications, guidelines,
  procedures,
• control methods, checklists (including
  HW/SW/equipment infrastructure) defined by
• - General quality guidelines
• - Producers (private companies) quality plan
  requirements
• - Product specifications
• - Control method descriptions
• - Specifications of sampling and tolerances for
  rejection and re-work of products
• developed and implemented in three hierarchical
  levels
• - I Level - base documents describing overall
  principles of quality control work
• - II Level - base documents defining the
  products and subproducts to be controled
• - Topographic digital (vector) data - TD
• - Topographic map (scale 125000) - TK25
• - Orthophoto maps (scale 15000) - DOF5
• - Aerial photo and ground control,
  aerotriangulation, scanned
• photo, digital terrain model - DTM
• - III Level - Procedures and checklists for
  undertaking all control work
• - Two important principles

• CRONO GIP - Croatian-Norwegian GeoInformational
  Project
• Support and assistance of the Kingdom of Norway
  (Ministry of Foreign Affairs, Norwegian
• Mapping Authority Statens Kartverk) to the
  Republic of Croatia (SGA CGI)
• I phase (June 24 2002 June 24 2003)
• - Establishment of the capacity within SGA to
  scan and vectorise existing paper
• maps (cadastral maps, Croatian basic maps in
  scale 15000, etc.)
• - Development and implementation of a database
  within SGA for storage and use
• of data resulting from the on-going production
  of new topographic maps in the
• scale 125000
• - Establishment of a capacity within CGI to
  control the quality of topographic data
• produced for the Croatian Government by
  private companies.
• II phase (June 25 2003 - running)
• - Production of digital cadastral maps within
  SGA to enhance the capacity
• developed by CRONO GIP I phase
• - Scanning and vectorisation of existing
  topographic maps in the scale 15000
• within SGA

• CONCLUSION
• Public-private cooperation model ("Croatian
  model") is operative but still under further
• development
• CGI QC System is operative but still under
  further development
• Public-private cooperation model gives very good
  and promising results in accordance with
• Croatian subjective and objective conditions
• Public-private cooperation model is example how
  each country can build their own specific
• solutions in respect to the national official
  geodata production mapping products
