Data Quality
Lineage:The groundwater and surface water information were derived from geology maps, topographic maps, aerial photographs and stereoscope interpretation and satellite imagery interpretation.
The hydrology information from standing water level measurements flows from springs, chemical analyses of groundwater samples and surveys of outcrops of recharge beds
Positional Accuracy:Positional accuracy of 250 metres from bore locations.
Attribute Accuracy:Attributes assigned according to the dominant feature. For example, several similar geological units have been grouped to describe a particular geology. Several bore sites describing yield or chemistry information have been grouped to describe a particular hydrology. From the geology and hydrology information the hydrogeology units was delineated.
Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in line work. Following polygon data topological rules, checks were performed to detect flaws in the spatial data structure. The coverage was cleaned, to eliminate any duplicates arcs. The coverage was built for arcs and polygon topologies. A label errors routine was run to detect unlabelled polygons. A node errors routine was run to identify pseudo nodes and dangles. Checks were done to unsure that all classified polygons are closed, nodes are formed at intersections of lines and that each polygon has only one label.
