 Census dissemination

 General recognition: collecting census data and analyzing
  it is important, but unless the results of this analysis are
  communicated effectively to their intended audience, the
  analysis will have little impact on real policy decisions.


 Conventional tools:
    Published tables and reports for general distribution
    Tables in unpublished form for limited distribution
    Database supplied upon request, or disseminated online (in this
     case it will be available only to connected populations)

  Dissemination challenges


 How to present the right data with the right context to meet
  users needs – To be user-oriented

 How to ensure that the most recent and most correct data
  are used and displayed-Use of ICT and data accessibility

 How to take advantage of the spatial dimension of census
  data

    Global geographic information management
    The Statistical Commission:

 (b) Recognized the importance of the integration of
  geographic and statistical information and the opportunities
  provided in that context by the swift development of information
  technology, noting that national statistical offices are playing an
  increasing role in such integration, especially in the area of
  census management;
 (c) Called upon all national statistical offices to actively
  participate, in partnership with relevant national authorities, in
  the further development of national geographic information
  capacity in the context of spatial data infrastructures,
  taking full advantage of information technology and focusing
  special attention on the area of improving statistical and
  geographic metadata compatibility;

  Map Products

 Reference Maps:
      Reference maps show the boundaries, names and codes of
       standard geographic areas on a background of selected road and
       water features.

 Thematic Maps:
      A thematic map shows the spatial distribution of one or more
       specific data themes for standard geographic areas: The map
       may be
          qualitative in nature (e.g., predominant farm types) or
          quantitative (e.g., percentage population change).
      The maps can be viewed on the Internet and downloaded for
       free (as PDF or EXE files).

  Digital Geographic Database for Dissemination

 Demand for digital geographic databases

 Census data are an important input in policy planning and
  academic analysis in many fields.

 Health service provision, educational resource allocation,
  design of utilities and infrastructure, and electoral planning
  are some applications where government agencies require
  spatially referenced small area population statistics.

 Commercial users employ such data                                  for     marketing
  applications and location-based decisions.

  Dynamic census atlases: “thematic maps on the fly”

 Alternative to a static census atlas:
      Serves the needs of users without GIS expertise, but who want
       more geographic information facilities than is possible with a pre-
       packaged static census atlas.


 Publishing of a digital map and database together with mapping
  software can allow users to produce custom maps of census
  indicators.

 Normally includes digital boundary files at a lower resolution
  than the full census database to allow fast drawing and low disk
  usage

Importance of the Web



  Key medium for the dissemination of census data
  All standard geographic products are disseminated on the
   Web
  Benefits from Web Dissemination:
          Improved timeliness
          Increased accessibility of products
          Broader reach of products
          Increased usability

  User-oriented, accessibility, web-based mapping

   What is a Mashup?

 A web application that
  combines data from more
  than one source into a
  single integrated tool
   an example is the use of
    data from Google Maps to
    add location information to
    statistical data, thereby
    creating a new and distinct
    web service that was not
    originally provided by either
    source

  How a Mashup works: APIs

 API is an abbreviation for Application Programming
  Interface, a set of routines, protocols, and tools for
  building software applications. A good API makes it easier to
  develop a program by providing all the building blocks. A
  programmer then puts the blocks together.

 Google Maps has a wide array of APIs that let you embed
  the robust functionality of Google Maps into your own
  website and applications, and overlay your own data on top
  of them.

 Web services today are frequently just Application
  Programming Interfaces (API) or web APIs that can
  be accessed over a network, such as the Internet,
  and executed on a remote system hosting the
  requested services.

 GIS APIs are designed to manage data for its
  delivery to a web browser client from a GIS server

 Conclusions
 Collecting and analyzing census data is very important, but
  unless the results of this analysis are communicated
  effectively to their intended audience, the analysis will have
  little impact on real policy decisions.
 Various tools are available
   -    User-oriented approach
   -    Data accessibility
   -    Geospatial-based approach

 Planning data dissemination
   The definition of geographic output products and the
     time of their release should be coordinated with the
     timetable for the overall Census project

 Trends


 The overall trend for web-based mapping is:

        with more highly interactive, user-driven client interfaces as
        well as the desire by the general internet user to see the
        underlying data as a 3D environment and not a 2D flat-earth
        map.

       Server-technology: service-oriented architecture (SOA) and
        broad spatial capabilities
