Background: The recurring inaccuracy in census figures is attriutable to the lacuna in pre-census
mapping.
Data Source and Method: Geographic Information System (GIS) tool was demonstrated for the 2006
pre-census enumeration area- (EA) mapping of 2 NPC analogue EAs of urban and rural localities in
Enugu State. An | l-tier EA template and a satellite image-based Geographical Information Technology
EA Framework were generated using the Arc GIS version 10.3. All NPC analogue EA maps were found
to fall short of the 12 spatial quality parameters viz; completeness, logical consistency, topological
consistency, positional, temporal and thematic accuracy, mathematical basis, reliability, geometric
accuracy, modernity, cartographic design and scientific and social value.
Results: A checklist audit analysis indicates that road and building are dominant EA features.
Conclusion:The application of a Geo-spatial data bank infrastructure within a Constituency Land
Information System (CLIS) was suggested to help in aligning the agency on a proper trajectory to meet
the targets of sustainable development.
