Vicmap Lite - Public Land Classification Polygon - 1:1,000,000 to 1:5,000,000

dataset: VMLITE_PUBLIC_LAND_SU3
This layer is part of Vicmap Lite and contains polygon features delineating public land areas. This Vicmap Lite dataset is suited for use between scales of 1: 1 million and 1 : 5 million. The polygons were sourced from PLMMT100PLY. The level of attribute information, the number of features and the number of vertices has been simplified to suit the 1:1 million - 1 : 5 million scale range. The concept of a Scale Use Code has been introduced to help control the level of detail displayed. THIS DATASET WAS LAST UPDATED IN AUGUST 2008

Lineage

Statement
Dataset Source: The dataset is derived from PLMMT100PLY via an ARC/INFO aml process called plmgen.aml This process performs the following steps. 1: copy the latest version of PLMMT100PLY from the SDE update area. 2: drop unwanted marine polygons. 3: add a field that reflects the "aspect ratio" of features in order to eliminate long skinny features. 4: drop unwanted polygons asssociated with linear features (ratio less than 100). 5: join mmtsource.lut items so that MMTGEN_ID value can be determined. 6: regroup polygons in source cover based on mmtgeneral and state values. 7: dissolve polygons in source cover based on plmgroup values. 8: eliminate undersize polygons in source cover based on scale code. 9: drop unwanted polygons where area less than 1000 ha. 10: generalize polygons in source cover using weed tolerance of 2000m. 11: dissolve remaining polygons in source cover based on plmgroup values. 12: copy resultant cover to SDE update area and load into SDE via SDMP process. Dataset Originality: Derived 
Description
Collection Method: Derived from source 
Description
Level of detail reduced to suit 1:1 million - 1:5 million scale range. Redundant attributes removed, Scale Use Code attribute added and populated.

COASTAL WATERS - term defines states water jurisdiction, being 3 nautical miles from the high water mark.. MARINE PARKS AND RESERVES - term to include marine national parks, marine sanctuaries, marine parks, marine reserves and marine & coastal parks, but excludes marine aquaculture areas. OTHER PUBLIC LAND - term to include coastal reserves, forest parks, public land water frontages, water production, community use areas, alpine resorts, marine aquaculture areas, earth resources (mining) areas, stone reserves, services & utilities areas, and uncategorized public land. PARKS AND RESERVES - term to include national parks, state parks, regional parks, coastal parks, national heritage park, wilderness parks, reference areas, nature conservation reserves, most natural features reserves, and historic & cultural features reserves. Excludes public land water frontages, community use areas, stone reserves, and CLRA reserves for services & utilities and so on. SOFTWOOD PLANTATION - term to include, only public land. Excludes hardwood plantations. STATE FOREST - term includes reserved forest. 
Positional Accuracy
Comments
The source line work was generalised using a 2000m weed tolerance. 
Conceptual Consistency
Comments
Areas less than 2000 ha that formed holes in the public land polygons or existed as discreet outlying areas have been deleted / eliminated. 
Missing Data
Comments
Statewide coverage complete for Victoria 
Excess Data
Comments
The original PLMMT100PLY mmtgeneral and state attributes are used to aggregate polygons into one of five broad management categories. These categories are: 1: Marine Parks and Reserves (State = 'Vic Coastal Waters') 2: Parks and Reserves (Mmtgeneral = 'Parks and Nature Conservation Reserves' OR 'Other Reserves' OR 'National Parks Act & Nature Conservation Reserves' OR 'Other Conservation Reserves') 3: State Forest (Mmtgeneral = 'State Forest') 4: Softwood Plantation (Mmtgeneral = 'Softwood Plantation') 5: Other Public Land (Mmtgeneral = 'Other Public Land' OR 'Unknown' OR 'Commonwealth Land')
