ngis_bore is a point feature class in which each point that represents the location of a bore feature and associated attributes. A bore is defined as having a single x, y and z location:

Multiple independently screened outlets or pipes (i.e. that can be pumped and/or metered separately) are regarded as a separate bore feature.

Multiple holes associated with the same jurisdictional bore identifier are regarded as a separate bore feature.

ngis_bore is part of the National Groundwater Information System (NGIS), which is a geodatabase for storing nationally consistent groundwater data based on the ArcHydro for Groundwater data model. Australian groundwater data is held by the lead water agency in each State and Territory. Each State/Territory uses a different database in terms of the software, data model and terminology. These databases are not typically spatially-enabled. Consequently significant data collation and pre-processing was traditionally needed prior to spatial and inter-jurisdictional/national analysis. NGIS is designed to collate, standardise and spatially-enable groundwater data into a single, national repository. In this way NGIS facilitates spatial and inter-jurisdictional/national analysis of groundwater data. NGIS also provides the contextual and spatial data needed to interpret the time-series groundwater data (level and chemistry) submitted to the Bureau through the Water Regulations (the Commonwealth legislation that requires named agencies to deliver water data to the Bureau under the Water Act).
