An influx of people on a particular area can result in a rapid spread of HIV and AIDS. Among many things, GIS has the ability to analyse and present data that is linked to location. The PCGIS was asked by AWISA (AIDS Workplace Programmes in Southern Africa) to carry out an analysis on data for the prevention of HIV and AIDS in five districts in Southern Province. The focus were road contractors and communities where the upgrading of the road will take place.
Scanned maps from the Road Development Agency showing the roads to be upgraded were provided to the centre. These maps were then geo-referenced and digitized. Analysis of the data involved a 10km buffer around the roads, to identify villages which might be affected.
At the end of the project seven maps were produced. Two big maps showing Southern Province chiefdoms; and Wards respectively, both showing the rural roads to be upgraded. This done because chief and councillors are cardinal stakeholders in planning. Moreover, detailed maps for Mazabuka (D676); Monze (D373 and U4); Choma (D364); Kalomo (D337) and Kazungula (U4k) districts were produced for roads within a radius of 10km. Social services such as hospital, schools were added the these maps to help ascertain weak areas in terms of service provision.
