A waterway with no tributaries is a first-order stream. Two first-order streams join to form a second-order stream and two second-order streams join to form a third-order stream and so on. The Stream Network line segments describe where water would flow according to a hydrological enforced 9 second digital elevation model at scale 1:250,000. The data was sourced from the Australian surface water hydrography geofabric data supplied by Commonwealth of Australia (Bureau of Meteorology). The Stream Order information were sourced from Commonwealth of Australia (Geoscience Australia) using a lookup table that was joined to the stream network.

The truncated set of attributes was intended to reduce the file size and are described in the Data Dictionary. Fields kept from the Stream Network dataset: Name, Hierarchy, Perennial, Segment No, SrcFType. Field kept from the Terrain look up table: Segment No, Strahler0Original data source 1: Geofabric V2.1.1 SH_Network.GDB - Feature class AHGFNetworkStream Original data source 2: National Environmental Stream Attributes - Terrain look up table - The Australian network stream dataset was clipped to an extent approximately 75km beyond the Northern Territory border. - The Terrain look up table was joined to the Stream Network dataset using the field SEGMENTNO. - This table also contains the field STRAHLER. The integers 1 to 7 are allocated to each segment number. - The output feature class NT_STREAM_ORDER has a smaller set of attributes to reduce the file size. (see Data Dictionary)
