Description
Department survey code (vegetation) MANDREG_10
This polygon spatial dataset provides new information on mangrove communities in the Darwin Region. All previous mangrove surveys were standardised and combined to produce one dataset. The survey area covers approximately 92,000 hectares of mangrove and salt flats and includes the Bynoe Harbour, Charles Point., Darwin Harbour, Shoal Bay, Gunn Point and Adelaide River mapping.
More detail on various aspects for Bynoe and Darwin Harbour is contained in the original reports. Map unit coding has changed from the original surveys for a small number of communities.
The original field surveys and mapping was undertaken from 1996 to 2018 at a mapping scale of 1:25,000 and 1:10,000.

Data Quality
Lineage:Map unit boundaries derived from manual interpretation of aerial photo imagery (circa 1996, 2001, 2015, and 2016), DEM, geological and topographic data. The original mapping of Darwin Harbour was updated in 2018 using high resolution aerial photography.
2016 mapping sourced from project funded by the INPEX-led Ichthys LNG Project as part of the Mangrove monitoring program for the Darwin Harbour Integrated Marine Monitoring and Research Program (IMMRP).
Field data (site information) described and classified according to national standards at the time of capture. Map unit polygons collected via geographic information system (ArcGIS).

- coordinate 131.236, -12.195 Polygon was mapunit 17 and changed to 9b.
- coordinate 131.356, -12.297 Polygon was mapunit 18 and changed to 5c.
- Map series published. See Map Index with links to 23 map products: www.ntlis.nt.gov.au/mpds/get_file?file_id=8922
- spatial data package updated.
Positional Accuracy:POLYGON DATA +/- 10 metres. Map unit boundaries digitised on screen directly from digital rectified aerial photographs. Level of accuracy of the initial ortho-rectified photos +/- 1 metre.
Attribute Accuracy:Digital data is attributed with label and broad description. Detailed attribute information is contained in the report accompanying the polygon spatial data.
Logical Consistency: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.
Completeness:Complete
