Following polygon data topology rules of must not overlap, must not have gaps and that each polygon has only one label; checks were performed to detect flaws in the spatial data structure. 0not knownPositional accuracy of 250 metres from bore locations0not knownAttributes 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.0The Oolloo and Florina formation boundaries 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. The Oolloo and Florina line work were captured using ArcGIS software in Shapefile format. The Shapefile includes the core attributes required for each survey. Using FME the Shapefile data was translated into the MapInfo Table. From the Shapefile the published map was drawn using MicroStation.
