As a part of a Victorian State Government initiative for Private Forest mapping was established to collect, collate and store forest resource information.
The PNF100 layer depicts forest stands interpreted visually from aerial photgraphs and image based mapping. A stand is an area of forest deemed to be homogenous in its species composition, crown cover, crown form, height and distribution for "modified code mapping".

Dataset Status:
PNF100 captures the forest stages of growth (relative age) in Private land where there is significant forested areas. National Park type mapping used within SFRI project forms the basis for the PNF100 mapping.
The area captured is the eastern part of the state (Zone55).
Areas not covered include the west of the State, Zone54.
Completeness Verification: The forest stand class linework, was validated by field checking, and referenced to existing map information and local knowledge.

Abstract:
As a part of a Victorian State Government initiative for Private Forest mapping was established to collect, collate and store forest resource information.
The PNF100 layer depicts forest stands interpreted visually from aerial photgraphs and image based mapping. A stand is an area of forest deemed to be homogenous in its species composition, crown cover, crown form, height and distribution for "modified code mapping".

Purpose:
The PNF100 layer has been designed for the digital spatial analysis of Victoria's Private forest resource. The high level of detail captured on Private land allows for a range of analyses. It is used by government and private industry to assess the quantities and qualities of forest resources.

Positional Accuracy:
The PNF100 layer is to be used with data sets that are commensurate with the Victorian Government's "VICMAP" 1:100,000 map scale digital map library. The data is designed to be stable for a fuzzy tolerance range of between 0.01 to 10 metres (ground units).
Attribute Accuracy:
Interpretation of aerial photographs (API) using specialised skills and codes according to Statewide Forest Resource Inventory: Forest Stand Classification (Forests Service Technical Reports 00-1) and the PNF classification.
Logical Consistency:
Polygon size is related to the type of mapping. All mapped polygons should exceed 7 hectares (ground units). Guidelines as used by DSE for forest stand mapping recommend polygon sizes of between 40 and 80 hectares for "modified code mapping". Larger polygons may arise due to the forest stand homogeneity. The polygon size minimum of 5 - 7 hectares and the Eucalypt crown-cover class is equal and /or greater than 4. (no less than 50%).
Data Source:
Dataset Source: Interpretation of aerial photographs (API), image based mapping and pre-existing growth stage mapping using specialised skills and codes according to the PNF standards. This includes size of the polygons min 7 ha, max size 80 ha, crown cover 4 or greater, and with no sub heights.

Additional Metadata:
Relationship to other Datasets: SFRI25VE growth stage has been used where it was mapped in the Private Land.
Current Design Issues: Attributes represent the full PNF100 code broken up into its individual components with added items that are generally seen in SFRIFRED. It's usability limited to data analysts trained in interpreting the code.
