Information is entered on available open file drillhole collars from companies and/or the Northern Territory Geological Survey. The data is captured by the department via compulsory reporting from exploration companies or analyses done by Geological Survey geologists. All data is stored in a SQL Server database: Prospect name, Company, Sample, Sheet number, etc.Only open file data available.

All drillhole collars are available from STRIKE (NTGS web mapping data delivery and viewing application (www.minerals.nt.gov.au).0not knownAll data is associated with four to six key fields common to each data template. Data maintains a logical grouping within these templates; key information, geological, analysis details etc.0not knownApproximately 20-150m metres using 100K topographical maps (AGD66) or GPS. Sites recorded using MGA94 (Map Grid of Australia). Decimal latitudes and longitudes are available for each site.0not knownAnalysis is performed by laboratories to set standards. Geological observations and descriptive attributes noted by Geological Survey geologists.0Relevant data is extracted in either supplied digital copy or from hard copy formats. Data is transferred to the database via data type templates e.g soil, rock, drill hole etc. Data is validated twice, at the template stage (before entry) and during loading into the database.
