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

2 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round 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

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

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

5 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round Census Enumeration Stage Pre-enumeration (EA Map Production) Enumeration (Census Data Collection) Large-scale maps EA units Geocoding System Census Database Digital Mapping GIS Satellite Imagery Aerial Photo. GPS GIS/GPS/PDAs Digital Mapping Large-scale maps Large & mid-scale for sup. Mid- & small-scale for manag. Admin./Statistical Units

6 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round Post-enumeration Stage Pre-enumeration (EA Map Production) Enumeration (Census Data Collection) Post-enumeration (Census Data Dissemination) Large-scale maps EA units Geocoding System Census Database Digital Mapping GIS Satellite Imagery Aerial Photo. GPS Large-scale maps Large & mid-scale for sup. Mid- & small-scale for manag. Admin./Statistical Units GPS GIS Digital Mapping Mid- & small-scale maps EA update Statistical Database Databases (Maintenance) GIS Internet Mapping Digital Mapping

7 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round Geospatial Technologies at all stages EAs Units Administrative and Reporting Units (Pre-enumeration)(Enumeration)(Post-enumeration) GIS Census Database Satellite Imagery GPS Aerial Photo. Digital Mapping GIS Digital Mapping GPS Statistical Database Databases Maintenance GIS Internet Mapping

8 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round 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

9 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round 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).

10 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round 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

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

12 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round  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.

13 UNSD-CELADE Regional Workshop on Census Cartography for the 2010 Latin America’s census round 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 

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

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

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