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

Census Geography Programme: a continuous process q 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. q 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

Census Geography programme q National Statistical Organizations should: n Develop GIS as a long term project: o To prepare the census enough in advance o Too expensive for the census only o To be used beyond the census as infrastructure for other statistical purposes (other sources, sample frame. . . ) n n 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 q A specialized in-house Cartography/GIS unit q Building technical and human capacities q National Spatial Data Infrastructure (NSDI) n n 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) ØGeographic Information: Infrastructure Concept ØImportant as physical infrastructure assets such as roads, communications networks, and other public utilities Info: http: //www. fgdc. gov/nsdi. html

q Geographic Information (or Spatial Data) Infrastructure Concept Ø The Spatial Data Infrastructure Concept: ü ü 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

Spatial Data Infrastructure (SDI) q Definition - the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data q Part of a nation’s e-Gov strategy q www.
