Mangrove mapping of Darwin Harbour, 1996

This polygon spatial dataset describes the mangrove communities for Darwin Harbour and its environs and was surveyed at a mapping scale of 1:25 000. The associated report notes an area of approximately 20,400 hectares of mangroves in Darwin Harbour and describes ten main mangrove associations or communities.

The data provides a basis for identifying the extent and distribution of mangrove communities for Darwin Harbour and its environs.

Report

Measure description
POLYGON DATA - Map unit boundaries transferred from aerial photographs to topographic maps, using the best available topographic mapping at the time (generally 1:100 000) via a mapograph. Level of accuracy depends on the number of control points on individual aerial photographs. Control points include creek lines, cadastre and other topographic features. Depending on the nature of the landscape (the number of control points), positional accuracy may vary. Positional accuracy generally considered moderate to high. POINT DATA - Site point coordinates collected from a geographic positioning system with general accuracy of within 100m. Selective availability during this time prevented increased accuracy.

Report

Measure description
The attribute information conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture. In November 2013 additional attribute values, as described in the Data Dictionary below, have been added to each polygon in the spatial dataset.

Name of measure
Logical consistency
Measure description
GIS editing tools were used to rectify all overshoots and undershoots in line work. Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.

Resource lineage

Statement
Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to topographic map sheets via a mapograph. Original maps were hardcopy only. With the advent of geographic information systems polygons were digitised by rectifying the original hard copy maps. Map unit boundaries derived using aerial photography and digital satellite imagery, geological and topographic data. Field data (site information) described and classified according to national standards at the time of capture. Map unit polygons collected via geographic information system. (ESRI ArcInfo) Vegetation attributes attached to map units may be unique to individual surveys.
