  1. Census Cartography: Organizational and Institutional Issues UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  2. Overview • From Census mapping to Census Geography: • Census Cartography Process • Building a geospatial Infrastructure: • In-house Cartography/GIS unit • Technical and human capacities • Standards • NSDI • Challenges • Conclusion UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  3. Census Process Pre-Census (Pre-enumeration:maps ensure consistency, prepare) Census (Enumeration: maps support data collection, monitor) Post-Census (Post-enumeration: analyze, display and disseminate) UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  4. Pre-enumeration stage Pre-enumeration (EA Map Production) Large-scale maps EA units Geocoding System Census Database Digital Mapping GIS Satellite Imagery Aerial Photo. GPS UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  5. Census Enumeration Stage Large-scale maps EA units Geocoding System Census Database Digital Mapping GIS Satellite Imagery Aerial Photo.

  6. Post-enumeration Stage Mid- & small-scale maps EA update Statistical Database Databases (Maintenance) GIS Internet Mapping Digital Mapping Large-scale maps EA units Geocoding System Census Database Digital Mapping GIS Satellite Imagery Aerial Photo.

  8. Census Geography Programme: a continuous process • The recommendations derived from our EGM and Workshops on GIS and census mapping emphasized the need for countries to consider the census geography programme as a continuous process, rather than the sequential mapping and dissemination operations. • It was also emphasized that the use of and application of contemporary geospatial technologies and geographical databases is beneficial at all stages of population and housing census process. Geospatial improve the efficiency in the preparatory, enumeration, processing and dissemination phases of the census UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  9. Census Geography programme National Statistical Organizations should: Develop GIS as a long term project: To prepare the census enough in advance Too expensive for the census only To be used beyond the census as infrastructure for other statistical purposes (other sources, sample frame...) Ensure the availability of adequate resources to that end; Actively participate, in partnership with other national authorities, in the development of a national geographical information capacity, including the National Spatial Data Infrastructure (SDI). UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  10. Institutional/Organizational Issues • A specialized in-house Cartography/GIS unit • Building technical and human capacities • National Spatial Data Infrastructure (NSDI) • Basic data • Population Datasets and Geocoding System: basic components UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  11. Spatial Data Infrastructure (SDI) • Geographic Information: • Infrastructure Concept • Important as physical infrastructure assets such as roads, communications networks, and other public utilities Info: http://www.fgdc.gov/nsdi/nsdi.html UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  12. Geographic Information (or Spatial Data) Infrastructure Concept • The Spatial Data Infrastructure Concept: • SDI= Policies+ Standards + Human-Resources +Techologies • Core Spatial Data (Framework Data): common - Geoditic Network – Administrative boundaries – Hydrography – Elevation – Roads and Railroads – Cadastre. UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  13. Spatial Data Infrastructure (SDI) • Definition - the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data • Part of a nation’s e-Gov strategy • www.GSDI.org UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  14. Framework Data (common)/ Reference Data • Geoditic network • Administrative Boundaries • Hydrography • Elevation • Roads and Railroads • Cadastral • Geographical Names UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  15. Main NSDI Components UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  16. NSDI Components…Cont. • Interoperable, framework data • Clearinghouses for data storage and access • Search tools for locating data • Metadata for data description UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  17. List of 13 Core Layers (UN)(tobe reviewed, Santiago Nov. 2006) • Transportation network/Roads/rails/Navigation routes • Population centres / gridded Population density • Hydrography / Hydrology / drainage network/ River and lake basins • Hydrogeology • Coastlines • Land-cover/Land-use • Hypsographic ( elevation contours) • Bathymetry • Landmine areas • Protected area / Restricted areas • Geology, geomorphology • Airports/Helipad • Health facilities UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  18. GI Standards • ISO/TC 211 • OpenGIS Consortium UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  19. A new Working Group on Census Cartography within ICA UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  20. Joint Board of Geospatial Information Societies (JB GIS) • FIG • ISPRS • ICA • IAG • IMTA • IHO • ISCGM UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round

  23. Implementing a GIS • Consider the strategic purpose • Plan for the planning • Determine technology requirements • Determine the end products • Define the system scope • Create a data design • Choose a data model • Determine system requirements • Analyze benefits and costs • Make an implementation plan Source: Thinking About GIS, Third EditionGeographic Information System Planning for Managers UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round
