GIS applications and base maps are available at the GJMC and
the MLCs but it has not been standardised and has not been used for systematising
environmental data. There is a need for the MLCs' Environmental Management Units to be
able to extract GIS based environmental information for the units' decision making,
especially for development control applications.
Surface water quality (chemical and biological)
Status of boreholes including quality and yield
Ambient air quality
Ambient noise and noise zoning
Meteorological data (rainfall, temp, wind speed & direction)
Pollution point sources (with pollution profiles)
Mining activities (incl. abandoned dumps)
Environmental/geo-technical hazardous areas
Environmental sensitive areas and ecological info.
Cultural, historical and archaeological resources
Stormwater runoff & flood lines
Environmental monitoring stations
Agricultural potential
System capable of accepting and locating erf details (to assess whether development
applications fall in hazardous or sensitive areas).
