1. The complete Process of Census/Surveys Data Processing – Where GIS can assist! Dr.-Ing. Jens Hartmann, Account Manager May 2008, Doha, Qatar

2. Agenda • Introduction to Intergraph • Benefits of GIS • Nigeria Census Geoportal • Why Intergraph?

3. 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$

4. 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.* *Source: DevInfo Digital Mapping Technical Note

5. 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) - 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) here here and here GI Systems bring benefit

10. 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 • Census activities are funded by EU

11. 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 User + public) • Absolutely standard driven (Open Geospatial Consortium (OGC) / Spatial Data Infrastructure (SDI))

12. Why Intergraph? • Proven, highly scalable GIS platform GeoMedia • Strength: data integration, validation, collection and analysis • Compliant to IT and GIS standards (e.g. SOA, OGC) • Leader in SDI technology • Integration with DevInfo • We are more than a software vendor, we are a solution company!
