NO GIS: Limited geospatial data for election management

Lack of an effective, coordinated, and integrated geographic information led to challenges in the 1994 Election.

Conclusion

  • The call for an effective, coordinated, and integrated geographic information in

preparation for the 1999 Elections led to a collaboration by the IEC, DLA and StatsSA to create the first continuous digital geographic database for the entire country;

  • Subsequently new datasets such as the National Address Dictionary (NAD) were

created and used to geocode voters or any other customers/topic of interest;

  • Increasing availability of imagery at higher resolution (satellite and aerial) and the

use of GPS technology gave us “a new set of eyes” or tools with which to examine and then enhance the quality of our datasets; and

  • Finally, among others, today’s successful GIS operation requires quality geographic

data.

  • We thank SANSA and other entities such as the NGI for giving us the datasets needed

to building a comprehensive and up to date basemap that facilitates effective election management.
