The 1:2,000,000 scale dataset identify areas of the Northern Territory which would be at risk of developing dryland salinity if large scale clearing of deep rooted vegetation were to take place. The results are applicable at a broad scale only. The groundwater salinity dataset and map was also produced from the dryland salinity dataset.

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 2000 metres from bore locations. 0not 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 dryland salinity risks and groundwater salinity units 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.
