Title: Metadata for the Cadastre Index Map based on Digital Ortophoto on 75 Municipalities in Dambovitza Co


1
Metadata for the Cadastre Index Map based on
Digital Ortophoto on 75 Municipalities in
Dambovitza County
  • Ionut Savoiu General Manager, BlomInfo Romania
  • Digital Geographic Data Conference
  • Budapest, 16-17th of April, 2004

2
Responsabilities on land registration
  • Interior and Public Administration Ministry -
    National Office for Cadastre Geodesy and
    Cartography
  • Ministry of Justice Land Book Offices

3
NOCGC
  • Initiates regulations, laws and technical
    specifications
  • Coordinates land reform activities
  • Certifies private surveyors and surveying
    companies
  • Maintains the state geodetic control point
    network
  • Coordinates and controls systematic and sporadic
    cadastral registrations
  • Together with the Ministry of Justice organises
    information exchange with Land Book offices

4
WB Project for Cadastre and Land Registration -
Components
  • Works (USD 0.1 million)
  • Goods (USD 2.0 million)
  • Technical services (USD 13.8 million)
  • Aerial photography and orthophoto mapping
  • Cadastre services based on (new) orthophoto maps
    or existing maps
  • Procurement and installation of a cadastre IT
    system
  • Consultant Services and Training (USD 1 million)
  • Institutional strengthening (USD 0.5 million)

5
WB Project for Cadastre and Land Registration -
Objectives
  • Create a new cadastre system and extend the Land
    Book system
  • Secure land ownership simplify land transaction
  • Create a dynamic land market support land
    consolidation
  • Support the development of a private sector

6
Cadastral records in Romania
  • Land use cadastre
  • Land book system
  • Land reform started in 1991
  • The new Cadastre Law in 1996

7
History pressure on land reforms
  • 1866 - Modern Romania
  • 1877,1918,1946 - Wars
  • 1962 Cooperativization
  • 1974 Land fund
  • 1991 De-cooperativization

8
Cost effective solution for some constraints
  • Time
  • Money
  • Low standardisation in cadastre
  • High accuracy of classic cadastre projects

9
Source data quality
10
Activities within geographic data sector
11
Cadastre index map based on orthophoto in
Dambovita County
  • Project area cca. 333,000 Ha
  • 75 Administrative territories (out of 84 County
    total)
  • First step divided in 9 Deliveries - initializing
  • Second step divided in 3 Deliveries data
    backlog update

12
Multi-source data availability
13
Cadastre index map based on orthophoto maps -
Problems with existing records
  • De jure de facto
  • Source documents errors
  • Geographic differences
  • Accuracy
  • Physical condition
  • Property location

14
Components of the index map
Vector
Graphic DB
Raster
Text DB

Metadata definition

Reasons to use metadata in the production system
  • Estabilish one to one relationship between text
    and graphic
  • Estabilish rules for information from different
    data sources mergeing
  • Estabilish data quality rutines on vector quality
    control steps

Data integration based on metadata
Data merging operation for properties with more

25
Land registration cost
26
Further steps to be done
  • More standardisation of the Index mapping concept
  • IT system implementation
  • Procedures for data updating and exchange with
    Land Book implementation
  • Procedures for quality improvement of the data
    from Land Reform
  • Data publication process regulation
  • Data dissemination
  • Procedures for mass registration
