Description

Abstract:

This polygon spatial dataset describes vegetation communities in the Gunn Point Area, north of Darwin in the Northern Territory.
The area was mapped at a scale of 1:25,000. The aim of the mapping was to improve upon the 1998 vegetation survey mapped at a scale of 1:100,000.
The extent of the Gunn Point Area covers approximated 70,800 ha. and is defined by the Howard Water Allocation Planning Areas north of Gunn Point Road to the coastline.

The information was compiled as part of: Mapping the Future Project - Gunn Point
This project has identified land capability, water availability and biodiversity values to support land planning and inform development potential over the Gunn Point area.
Reports and maps can be viewed from the Mapping the Future webpage: denr.nt.gov.au/land-resource-management/development-opportunities

Data Quality

Lineage:Map unit boundaries were delineated on screen from NTLIS Google Earth Imagery 19082013, World Imagery, Sentinel 2B Satellite Image 20170828 surface reflectance.

Other surveys referenced in this mapping include;
- Remnant Vegetation of the Litchfield Region, 1998
- Darwin Region Mangroves, 2017
- Howard River Sand Plains Site of Conservation Significance (SOCS), 2013
- NT Land Use Mapping 2016
- Monsoon Vine-Forest Distribution (Rainforests)

Positional Accuracy:Polygon data:
Map unit boundaries digitised on screen directly from digital rectified field maps. Level of accuracy depends on the number of control points on individual map sheets. Control points exclusively used Map Grid of Australia (MGA) grid lines. Depending on the nature of the landscape (the number of control points), positional accuracy may vary. Positional accuracy generally considered high to very high.
Point data:
Site point coordinates derived from a geographic positioning system with general accuracy of within 10-50m.

Attribute Accuracy:Field data (site information) described and classified according to national standards at the time of capture. Attribute values are assigned to each polygon and described in the Data Dictionary below. The attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied to an ESRI file geo-database format.

3 additional attributes have been compiled by the department's biodiversity group to join to each Vegetation Community Map Unit to describe: Fauna Flag (identification of species); High Probability of Cycas armstrongii; Groundwater Dependent Ecosystem presence (seasonal or permanent). Refer to Supplementary Information in this metadata record to access data and this additional table.

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

Data Dictionary

Attribute Attribute Description Possible Code Code Description

01. SURVEY_NME Alias: Survey Name
The name of the survey area or report to which the mapping refers.

02. SURVEY_ID Alias: Survey Identifier
A department code that usually refers to the first five characters from the original survey and recorded on site sheets.

03. COMMUNITY Alias: Community Map Unit
Each map unit polygon is labelled to represent a community classification.

04. VEG_SYS Alias: Vegetation Classification System
Vegetation Classification System used to classify the vegetation community.

05. COM_GROUP Alias: Community Group
A broad floristic group describing the dominant community.

06. VEG_STRUC Alias: Dominant Vegetation Structure
Describing the structure of the dominant vegetation community.

07. COM_DESC_1 Alias: Community Description 1
Description of the dominant vegetation community.

08. COM_DESC_2 Alias: Additional community description 2
Additional community data including species and strata information.

09. COM_DESC_3 Alias: Additional community description 3
Additional community data including habitat or site preference information.

10. SIGSPECIES Alias: Significant/Threatened/Rare species
Flora records pertaining to critically endangered, endangered, vulnerable, near threatened and data deficient species. Flora Atlas N.T. should always be referenced for the most up to date information.

11. SIGHABITAT Alias: Significant vegetation habitat
Significant vegetation habitats as defined by the Land Clearing Guidelines 2018.

12. ORIG_UNIT Alias: Origin - Map unit
Map unit from the original survey report.

13. ORIG_SURV Alias: Origin - Survey report
Survey report from which the map unit information is derived.

14. ORIG_NOTES Alias: Origin - Additional Notes

15. SIM_SS_RF Alias: Similar Sandsheet Heath/Rainforest
Mapunits in the detailed (scale 1:10 000) Howard Sand Plains Site of Conservation Significance (Liddle et al 2013) that have similar habitat or species values to the broader sandsheet heath or rainforest communities described in the (scale range 1:25 000 - 1:100 000) Gunn Point/Litchfield Shire mapunits.
