Groundwater Monitoring Networks

Dataset Number1023
Dataset TitleGroundwater Monitoring Networks
CustodianData Authority: Department for Environment and Water
Data Provider: Department for Environment and Water

Description

DescriptionLayer which contains all of the monitoring networks data. Ie it specifies the monitoring networks name, whether the well is historic or current in the network, the frequency of monitoring etc. This layer spatially represents the data in SA Geodata. If a wells is not or has never been part of a monitoring network it will not appear in this data set.
UsageMonitoring groundwater characteristics.

Data Quality

LineageData points are part of the WATER.Drillholes dataset, from which attribute data fields not related to monitoring are obtained.
CompletenessComplete. Contains all drill holes that are part of the monitoring network.
Positional AccuracyNo positional accuracy field has been included in the database. In general the most accurate means of positioning the well has been used (positioned by GPS) +/- 30 metres.
