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.* *Source: DevInfo Digital Mapping Technical Note
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 here here and here GI Systems bring benefit
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)
Samples Tracking EA + backdrop Query results
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!
