Dataset  
Purpose
FMA25 is the key layer at 1:25 000 for all departmental forest management activities. This layer is used to provide the basic spatial framework within which cartographic products assisting forest management plans are derived. This layer will be superceded by FORMB25 when it is complete for the whole State.

Supplemental Information
History: FMA25 was created to eliminate the problem of FMA boundaries not matching existing 1:25000 information on digital and hardcopy maps generated for the SFRI project. Relationship to other Datasets: Most of the features in this coverage were derived from the following layers: HYDRO25, ROAD25, CONT25, FORMB25, HYDROP25, LANDMMT25, RAIL25, SHORE25, PARCEL and FMA100. Current Design Issues: FMA25 boundary arcs, where it could not be determined where the corresponding arc in FMA100 was originally sourced (i.e. not found in HYDRO25, ROAD25, CONT25, FORMB25, HYDROP25, LANDMMT25, RAIL25, SHORE25 or PARCEL), were manually digitised based on an estimation of the most logical alignment of the arc. Boundary arcs that appeared to follow ridgelines in FMA100 where generated using a DEM created from the CONT25 library layer. Related Documents: None Refer to the metadata of the following layers: HYDRO25, ROAD25, CONT25, FORMB25, HYDROP25, LANDMMT25, RAIL25, SHORE25, PARCEL and FMA100.

Statement
Dataset Source: FMA25 was created using arcs and boundary information from the following datasets: HYDRO25, ROAD25, CONT25, FORMB25, HYDROP25, LANDMMT25, RAIL25, SHORE25, PARCEL and FMA100. Refer to the metadata for these layers for more detailed information of there origin. Dataset Originality: Derived 
Description
Collection Method: Maps, Existing Datasets 
Description
The template for FMA25 was derived from FMA100. The as2482 attributes in FMA100.aat formed the basis for extracting the arcs from either HYDRO25, ROAD25, CONT25, FORMB25, HYDROP25, LANDMMT25, RAIL25, SHORE25 or PARCEL in order to produce a 1:25000 FMA layer. All polygon attributes come directly from FMA100.

Quality

Attribute Quality
Comments
All arc features derived from another layer are validated within that layer prior to being copied into FMA25. All arc features captured within Drafting are coded for AS2482. Those that were supplied by the Area may not necessarily have retained the AS2482 code. All labels are coded for FMA name. 
Positional Accuracy
Comments
Precision: Boundary accuracy 25-50m Determination: Estimate 
Conceptual Consistency
Comments
All values contained In the AAT and the PATs have been checked against the appropriate lists of valid codes. 
Missing Data
Comments
All areas which are covered by a published Forest Management Plan are accounted for. All polygons contain an FMA name and number. All arcs are atrributed for their original AS2482 sourced from other 1:25000 datasets (AS2482_25) and the AS2482 from corresponding arcs in FMA100 (AS2482_100).
