census process
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)

census geography programme a continuous process
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

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).

institutional organizational issues
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

spatial data infrastructure sdi

Spatial Data Infrastructure (SDI)

  • Geographic Information:
  • Infrastructure Concept
  • Important as physical infrastructure assets such as roads, communications networks, and other public utilities

slide12
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.

spatial data infrastructure sdi13
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

Framework Data (common)/ Reference Data
  • Geoditic network

  • Elevation
  • Roads and Railroads
  • Cadastral
  • Geographical Names

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
