Lineage

Line work was drawn onto 1:25000 plots of rectified SPOT 5 2004/2005 imagery. ; ; Information plotted onto the rectified SPOT 5 imagery prior to mapping included:; ; * The cadastral layer from the NSW Digital Cadastral Database; * Boundaries of State Forests, National Parks and Nature Reserves from the NSW Digital Cadastral Database; * Specific areas of interest included the 1:100000 topographic sheet boundaries displayed by Camberwell, Cessnock, Dungog, Gulgong, Howes Valley, Merriwa, Mt Pomany, Mudgee, Muswellbrook and Newcastle.; ; Mapping was drafted directly onto the rectified SPOT 5 mosaics using the aerial photography, information conveyed by the Spot 5 image, local knowledge and field checking as the main data sources. Subsequent editing of polygon features was then done on-screen using the relevant SPOT5 image as a backdrop.; ; Mt Pomany was mapped directly on screen with reference to imagery and photos.; ; Details of the aerial photography are:; Camberwell NSW 4924, 4928 & 4931-4932 Runs 1-13, Flown between October and December 2005, Scale 1:25000;; * Cessnock NSW 4873 & 4874 Runs 1-13, Flown September 2004, Scale 1:25 000;; * Dungog NSW 4924, 4928, 4931 & 4932 Runs 1-13, Flown between October and December 2005, Scale 1:25000;; * Gulgong NSW 4502-4503 &4505 Runs 1-13, Flown between January and May 2000, Scale 1:25000;; * Howes Valley NSW 4580 & 4585 Runs 1-13, Flown between September and October 2001, Scale 1:25000;; * Merriwa NSW 4796 & 4797 Runs 1-13, Flown September 2003, Scale 1:25000;; * Mt Pomany NSW 4572, 4580, 4582-4583 & 4585 Runs 1-9, Flown between August and October 2001, Scale 1:25000;; * Mudgee NSW 4838 Runs 1-4, Flown March 2004, Scale 1:25000;; * Muswellbrook NSW 4782 & 4796 Runs 1-13, Flown between August and September 2003, Scale 1:25000;; * Newcastle NSW 4873-4876 Runs 1-13, Flown September to October 2004, Scale 1:25000; ; Details of the SPOT5 are:; 15/11/2004; 25/11/2004; 21/12/2004; 11/01/2005; 22/01/2005; 06/02/2005; 11/02/2005; 15/03/2005; ; Where details such as cropping patterns and mining boundaries differed between aerial photographs and SPOT5 images, the pattern displayed on the aerial photographs, when used, took preference.; ; Field verification has been carried out in the Camberwell, Cessnock , Dungog, Merriwa, and Muswellbrook 1:100000 map sheet areas and partially in the Gulgong and Newcastle 1:100000 map sheet areas where legal normal vehicular access allowed.

Explanation

Land use mapping encompassing the Hunter catchment commenced in February 2006 and was completed in September 2012. The project acquired aerial photography covering discrete areas and affordable high resolution SPOT 5 imagery, which was used to update the previous 2002/2003 land use mapping.

Effective date

2001-01-01

Explanation

One of the major changes compared to the previous land use mapping was the inclusion of farm dams (code 8) and individual farm infrastructure (code 139) as mappable features. Whilst both these features account numerically for a large portion of the total polygons it should be noted that not all features have been captured.; ; Mapping was not undertaken for the Hunter Catchment on the Gosford 100K sheet.

Effective date

1900-01-01

Explanation

Mapping was drafted directly onto the rectified SPOT 5 mosaics using the aerial photography, information conveyed by the Spot 5 image, local knowledge and field checking as the main data sources. Subsequent editing of polygon features was then done on-screen using the relevant SPOT5 image as a backdrop.

Effective date

1900-01-01

Explanation

The following checks have been run on the spatial information throughout processing and after merging of the 100K tiles.; ; * Check and Repair Geometry;; * Dissolve;; * Topology (Must not overlap and Must not have gaps) with a cluster tolerance of 0.0000009;; * Removal of small polygons/slivers;; * Identify and remove anomalies between sheets;; * Explode multi part features; and; * All polygons are tagged and their attribution conforms to the LUMAP code list

Explanation

Boundaries from existing corporate spatial layers have been incorporated into the dataset between March 2011 and September 2012. It is possible that in some instances these boundaries may have changed since 2004/2005. These boundaries include:; ; National Parks Estate (NPE); P:\Corporate\Themes\Tenure\CrownEstate\CrownEstate.gdb; Feature Class: NPWS_Estate; ; State Forests (SF); P:\Corporate\Themes\Tenure\CrownEstate\CrownEstate.gdb; Feature Class: FNSW_Boundaries; ; Road corridor (19) P:\Corporate\Themes\Tenure\Cadastre\Cadastre.gdb; Feature Class: RoadCorridor; ; Rail corridor (20); P:\Corporate\Themes\Tenure\Cadastre\Cadastre.gdb; Feature Class: RailwayCorridor; ; The road and rail corridors have been extracted where it can be seen that they represent a sealed surface or rail network outside urban areas. On occasions, these were slightly modified to account for actual roads that show up on the SPOT5 image. ; ; Other existing spatial layers have also had their features incorporated into the dataset but not always uniformly to all sheets. These features include: ; ; Water bodies; P:\Corporate\Themes\Water\Drainage\Drainage.gdb; Feature Class: HydroArea; ; TSR's; P:\Corporate\Themes\Tenure\CrownEstate\CrownEstate.gdb; Feature Class: TravellingStockRoutes; ; The OEH (formally DIPNR) spatial database for Property Agreements and Management Contracts has not been incorporated into the data set.; ; Polygon boundaries were generally assessed (but not in all cases) and adjusted to coincide with the 2004/2005 spot imagery. Accuracy of the polygon boundaries is generally within 10m.

Explanation

The attributes of this data set are defined by the LUMAP mapping code classification (version 40). Attributes in this classification are generally recognisable from 1:25000 colour aerial photographs as being sufficiently distinct from all others to warrant a separate description. In addition, cadastral boundaries have been used as a guide to delineate additional land parcels which are not entirely clarified by the above method, but are still associated with a particular land use by virtue of a perceived ownership.; ; The majority of the land uses are described to the secondary or tertiary level.; ; All polygons have been checked to see that they are attribution and that the attribution conforms to the LUMAP code list.
