Title: NEW SOUTH WALES DTDB LANDFORM THEME 5M DIGITAL TERRAIN MODEL
Custodian: Department of Information Technology and Management (LPI)
Jurisdiction: New South Wales
These are high resolution 5 metre Digital Terrain Model spatial partitions generated from the Land Information Centres Large Scale Contour Archive. The partitions are 9 kilometers by 7.5 kilometres and align to the ISG 1:10000 zone coverage of New South Wales. This theme contains DTM's created from existing 2 metre contours sourced from the 1:4000 Orthophoto Map Series of the NSW topographic map archive .

- Geographic extent name:
- NEW SOUTH WALES - State or Territory - New South Wales
- Geographic extent polygon:
- 141 -37.5, 154 -37.5, 154 -28, 141 -28, 141 -37.5

Geographic bounding box:
The bounding box encloses the maximum extents of the dataset. There may be voids or gaps within the bounding box, depending on the defined coverage of the dataset. Outer bounding rectangle as Latitude/Longitude coordinates based on the WGS84 datum (expressed as both Degrees Minutes Seconds and as decimal Degrees):
- North bounding latitude: 28 00 00.0 S (-28)
- South bounding latitude: 37 30 00.0 S (-37.5)
- East bounding longitude: 154 00 00.0 E (154)
- West bounding longitude: 141 00 00.0 E (141)
Lineage:
Topographic 3 dimensional 5 metre grid data derived from contour and drainage data sourced from the New South Wales Topographic Large Scale Map Archive (pre 1995). Predominantly 2 metre contours used as source data.
Positional accuracy:
Initial digital contour collection is within 0.2mm of map transparencies at scales of 1:4000. Vertical accuracy of a DTM is to within 0.5 of the source document contour interval.
Attribute accuracy:
NA
Logical consistency:
Data partitions are edge matched to adjoining partitions where applicable.
Completeness:
Current data availability is restricted to partial coverage of the Eastern zone of New South Wales. As data update proceeds, overall coverage will increase.
