census and gis
Census and GIS?
  • Census data are spatial data in it‘s nature
  • Geographic Information Systems (GIS) can collect, store, manage, analyse and reproduce spatial data
  • GIS link a data value (e.g. census data sets) to a geographical feature (e.g. enumeration area).
  • GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps.*

the process steps of census data processing
The process steps of Census data processing
  • Pre-Enumeration
  • Integration of existing paper maps
  • Integration of aerial or satellite imagery
  • Converting existing data to census data model
  • Updating existing data sets
  • Conduction planning and optimisation

Post-Enumeration

- Geocoding of result sets

- Data integrity checks

- Systematic error analysis

- Data dissemination (internally/public)

- Quality Assurance

- Spatially enable OLAP Analysis

- Thematic Mapping

- Advanced Spatial Analysis

- Planning the next steps

Enumeration

- Conduction planning and optimisation

- Progress review

- Mobile data collection (GPS supported)

- Quality Assurance

status of gis
Status of GIS
  • GIS is a mature technology with rich functionality for
    • Geocoding
    • Visualization
    • Analysis
    • Map production
  • Remaining challenges
    • Data integration / harmonization / validation
    • Interoperability / systems integration with other systems
    • Dissemination of data itself
    • Workflow / process support for non professional users
un spatial data infrastructure
UN Spatial Data Infrastructure
  • Goals
    • Reuse data and systems (nationwide and internationally)
    • live access to distributed, decentralized geospatial data
  • Principles
    • no monolithic GIS-platforms, but open
    • use of Interoperable Geospatial Services (Open Geospatial Consortium as THE standardization body)
    • using metadata (ISO) to make geospatial data
      • discoverable
      • accessible
      • re-usable
what unsdi means for census
What UNSDI means for Census?
  • Easy integration of existing data of other national or regional bodies using standard interfaces (OGC)
  • Each institution cares for the updates of it’s own data
  • Standardized documentation helps for internal processes and external reuse (UN, other national institutes)
  • Using standards secures your data and your system itself
  • SDI is a Megatrend in the field of GIS (e.g. Global (G)SDI, European INSPIRE), so it should also be adopted for census
best practices in sdi nigeria census geoportal

Best practices in SDI:Nigeria Census Geoportal

Dr.-Ing. Jens Hartmann, Account Manager

December 2008, Minsk, Belarus

nigeria census geoportal
Nigeria Census Geoportal
  • National Population Commission of Nigeria (140 Mio (!) Inhabitants, Area 920.000 km²)
  • “It has the statutory powers to collect, analyze and disseminate population/demographic data in the country”
  • Last Census was conducted in 2006  Post-Enumeration activity
  • Census activities are funded by EU
nigeria census geoportal17
Nigeria Census Geoportal
  • Intergraph Tasks
    • Setting up spatially enable database (open integration with tabular census data provided by Beta Systems)
    • Process integration with Beta Systems Solution
    • Data migration of existing reference, topography data and satellite imagery
    • Data validation
    • Data documentation (metadata!)
    • Data dissemination by Geoportal (Internally/Power Users + Public)
    • Absolutely standard driven (Open Geospatial Consortium (OGC) / Spatial Data Infrastructure (SDI))
mobile data collection

Mobile Data Collection

Data capturing

Mobile Data collection
  • Intergraph OnDemand
    • Mobile GIS
    • GPS Interface
    • Rich map display (vector/raster)
    • data editing/collection capabilities (spatial/alphanumerical)
    • Full programming API to build custom applications (e.g. Survey, Census forms)
    • Proven data sync process (desktop file sync / web over GSM/GPRS/UMTS network)
    • Runs on windows mobile (any standard PDA)
