Census and gis l.jpg
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 l.jpg
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


- 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


- Conduction planning and optimisation

- Progress review

- Mobile data collection (GPS supported)

- Quality Assurance

GI Systems bring benefit

Status of gis l.jpg
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 l.jpg
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 l.jpg
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

Nigeria census geoportal l.jpg
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

  • 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))
