Description

Abstract:

Is a reconnaissance level survey (1:250,000 scale dataset) that is the output product from a ongoing regional mapping programme to map mangrove communities along the Northern Territory Coastline. This is a first cut dataset showing the existing mangrove coverage for the NT coastline, this dataset was regionalised to give areas for community detail. Mapped information describes mangrove communities/vegetation units and their attributes as floristic and environmental data and provides a basis for identifying the extent and distribution of mangrove community resources for the Northern Territory. (Vegetation Unit - A reasonably homogeneous part of the land surface, distinct from surrounding terrain with constant properties in landform and vegetation) - see online linkage for asociated mangrove mapping datasets.

Data Quality

Lineage:Original linework compiled/determined using the AUSLIG 1:250,000 GEODATA water body layer - available for mangroves, and combined with 1:1,000,000 landsat TM image to give mangrove area coverage per 1:100,000 ATSS mapsheets. Resultant linework input into GIS system as ArcInfo vector information then built as a polygon cover. Recompiled and updated to GDA94 as part of ongoing GIS Progarm 2004.
Source data
Landsat TM - 1:1,000,000 Col
Base map - AUSLIG GEODATA 1:250,000 water body layer AGD66
- Australian Topographic Survey Series 1:250,000 AGD66
- Australian Topographic Survey Series 1:100,000 AGD66
- Northern Territory Cadastre AGD66
GIS - ArcInfo vector as AGD66/GDA94

Positional Accuracy:Good - Derived from topographic basemap and NT cadastre. The summation of errors from all sources results in data with a standard deviation defined by scale used as +/-500m for well-defined points.

Attribute Accuracy:High - The accuracy of the attribute information is considered high and conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture.

Logical Consistency:Good - Dataset topological consistency has been system checked and all classified polygons are closed, nodes are formed at the intersection of lines and there is only one label within each polygon. Polygons have been classified for mangrove community groupings ID in the lookup table.

Completeness:Judged complete at this stage - spatial and attribute verification of the dataset has been performed. Digital cover is available for export.
