Title

Forest Management Area boundaries 

Alternate title

FMA25 

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 This layer will be superceded by FORMB25 when it is complete for the whole State.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.
