Agenda

  • Introduction to Intergraph

  • GIS and SDI

  • Nigeria Census Geoportal

  • Mobile data collection

  • Why Intergraph?


Intergraph Corporation

  • Leading global provider of Spatial Information Management (SIM) solutions

  • We deliver software and services that enable customers to manage and understand complex data through intelligent visual representations

  • Governments and businesses in over 60 countries rely on our software and services

  • Founded 1969 in Huntsville, Alabama/USA

  • 3.500 Employees

  • Revenue 2007: 725 Mio. US$

  • Operating EBITDA 2007: 144 Mio. US$


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

  • 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

  • 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

  • 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?

  • 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

Dr.-Ing. Jens Hartmann, Account Manager

December 2008, Minsk, Belarus


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 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

Dr.-Ing. Jens Hartmann, Account Manager

December 2008, Minsk, Belarus


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)

Mobile GPS Devices

  • GPS incl. Storage unit (USB)

  • Direct download to Intergraph GeoMedia

  • Optional

    • Numerical keyboard

    • Display

    • Bar code scanner

    • GPRS modem

    • Photo camera

    • Digital compass

    • 3D Motion sensor (indoor nav)


  • Coded coordinates incl. checksum

  • Less digits to read/write

  • Data integrity check included

  • Of no use outside the survey context

Realtime satellite clock

  • Time of the last valid GPS position

  • No noting outside the house required

Low Cost Mobile Device

  • Clipboard integrated GPS device

  • note GPS coordinate to the paper questionaire


Why Intergraph?

  • Proven, highly scalable GIS platform GeoMedia

  • Strengths: full data integration (ESRI, MapInfo, AutoCAD, Microstation etc.), validation, collection and analysis

  • Compliant to IT and GIS standards (e.g. SOA, OGC)

  • Leader in SDI technology

  • Integration with DevInfo and Google

  • We are more than a software vendor, we are a solutions company!
