Description
This polyline spatial dataset displays mapped streams over the Northern Territory including a 70 km buffer beyond the border.
The drainage lines are displayed in three separate datasets; Major, Minor and Streams.
The mapped stream data was sourced from the Australian Hydrological Geospatial Fabric (AHGF Geofabric) V3.2 via the Commonwealth of Australia (Bureau of Meteorology).

Data Quality
Lineage:22 January 2019
Data source: Geofabric V2.1.1; SH_Cartography.GDB; Feature Class: AHGFMappedStream
Download complete datasets from Bureau of Meterology: www.bom.gov.au/water/geofabric/
ESRI ArcGIS V10.5 was used to clip the Australian wide dataset to 70km beyond the borders of the Northern Territory and separate the drainage into 3 datasets using the following queries;
MAJOR - hierarchy = 'Major'
MINOR - Name IS NOT NULL and Name <> ' ' AND Hierarchy = 'Minor'
STREAM - Name IS NULL OR Name = ' '
All attributes, other than Name and Hierarchy, were removed from the dataset. Named streams were converted from CAPITAL LETTERS to Title Case. The lines were dissolved using the field NAME to reduce the number of nodes.

Supplementary Information
Data display in NR Maps. See nrmaps.nt.gov.au/nrmaps.html
Folder: Surface Water Drainage.
- The 3 drainage line datasets are displayed as Major, Minor and Streams.
- Drainage bodies displayed in NR Maps are sourced from a Web Map Server (WMS) via Bureau of Meterology. These are Version 2 Geofabric.
- Stream Orders V2: refer to metadata record www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=72F5883FB7117F2DE050CD9B21444A59.
Drainage Bodies from Geofabric V3 were clipped to the Northern Territory (+70km).
