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
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).
