Recommendations - General

The meeting recommended and strongly supported the use of geo-spatial and Geographical Information Systems technologies for the 2010 round of population and housing censuses, taking into consideration national and local circumstances.



National Statistical Organizations should:Develop and set-up institutional and organizational structures to implement a census geography programme;Ensure the availability of adequate resources to that end;Institute and maintain training programmes for national staff;Develop mechanisms for retaining GIS trained staff; andActively participate, in partnership with other national authorities, in the development of a national geographical information capacity, including the National Spatial Data Infrastructure (SDI).



United Nations Statistics Division should:

Continue to facilitate exchange of national experiences

Introduce on-line facility including e-learning material for exchange and sharing of knowledge

Compile lessons learned emphasizing advnatges and limitations

Develop guidelines for census geography


Recommendations - Use of contemporary technologies for census geography

Applying these technologies (satellite imagery, aerial photography, GPS, GIS) is beneficial to the efficiency and quality of the population and housing census, specifically for

Delineation of enumeration areasSupervision of data collectionDissemination at small area level

Single solution does not fit allSignificant investment in hardware, software and human capital


Recommendations - Geo-coding for statistical purposes

Geo-coding: Associating geographical to features such as structures, buildings, dwellings, streets, addresses, enumeration areasDifferent methods – GPS, PDA, satellite imageryNational statistical agencies need to consider geo-coding approach for 2010 round of censusesGeographical coding schemes – harmonization and uniformityDwelling Frame/Address Registry


Recommendations - Geographical databases and data dissemination

Significant value of geographical database for census data collection, processing and dissemination for small areasInclusion on non-census items such as schools, roads, rivers, settlements …Long-term and significant commitment is crucialNational statistical agencies should develop web-based mapping tools


Recommendations - Handbook on geographic information systems and digital mapping

Current issue – still valuableRequires updates and reviewPutting a focus on censusesEmphasizing continuous character of census geography programmes


Handbook on Geospatial Infrastructure/Census

Held and Expert Group Meeting to Review the Draft Handbook on Geospatial Infrastructure in support of Census Activities on 7 – 10 April 2008 at HQ, New York

Brought together 8 experts from NSOs, the consultant responsible for preparing the draft Handbook, and representatives from WHO, OCHA and ECA


Background reasoning for the revision

Due to new technological developments, approaches and applications

Requests from countries to focus more on the use of geospatial tools for census mapping operations

Recommendations from P&R, EGM and Workshops underscored the fact that census mapping gain to be a geo-centric and continuous process

NSOs needed to have some practical guidelines on how to integrate GIS, GPS, RS and other geospatial technologies with census mapping operations


Reasons for the structuring of the Handbook

Reo-organize the sequence of sections of the Handbook that better reflect the integration of GIS and other geospatial toolsinto the census mapping process

General comments:Target both census practitioners and the heads of statistical agencies

Inclusion of an introductory executive summary aimed specifically at heads of statistical agencies

Be simple, address main concerns and be written in a self-contained “cookbook” format that targets both technical and managerial census personnel


Reasons for the structuring of the Handbook

General Comments (cont.)Emphasize results and efficiency gains from developing a geospatial infrastructure for census activities

Efficiency arguments be merged with cost benefits (investments and benefits)

Critical success factors for geospatial implementation be expanded

Re-organize the sequence of the Handbook to better reflect the integration of GIS and other geospatial tools into the census mapping process


Conclusions & Recommendations

A number of detailed suggestions for revision of the draft were made by the Group

Focus of the handbookTarget AudienceStructure of the handbookInstitutional collaborationPlanningMetadataQuality AssuranceTechnologyDisseminationHandbook TimelineAddressing Systems



Focus of the handbookfocus on the geospatial infrastructure and techniques to support the census process

Target Audienceprovide technical guidance and best practices in the implementation of the census process, and heads of statistical agencies to advocate for the use of geospatial technologies for the census and other statistical activities.

Structure of the handbookbe simple and as practical as possible, and expressed the need for the handbook to attract a wide range of users and to appeal to both census mapping practitioners and executive decision-makers



Institutional collaborationHighlight collaboration and partnerships for building and maintaining the geospatial infrastructure to support census activities

PlanningEnsure that the geospatial tools serve all aspects and stages of the census process, the plan should start from the outputs and services of the census and then work backwards through the stages and activities to the beginning

MetadataThe development of metadata should take into account two key us communities- external and internal users.



Quality AssuranceDeveloping standard protocols for geospatial data processes to enhance the quality of the geospatial infrastructure

Technologydefine the required functionalities needed in a software/hardware technology for census mapping rather than citing specific technology options

Disseminationdissemination strategy should consider the widest scope of uses and needs with special attention to disaster management and humanitarian response



Addressing Systems

Attention to the development of address systems and dwelling frames to guide some developing countries

Handbook Timeline

Circulate them among the experts for review and integrate their comments and recommendations as quickly as possible for wide dissemination as quickly as possible in light of the 2010 round of Population and Housing Censuses


Conclusion

The new revised Handbook is titled:

Handbook on Geospatial Infrastructure in Support of Census Activities

The Handbook is under editing

The Handbook will be published in the next few months
