Title

Forest Management Areas 

Alternate title

FMA500 

Purpose

FMA500 is the key layer for statewide overview of departmental forest management activities. It derived from the FMA regions of FORMB100 with generalised linework to 500 metres.

Supplemental Information

History: FORMB100 was created to replace the original BLOCK100 coverage. which only contains linework for the eastern half of the State. With the introduction of 'regions' into ARC/INFO it is now possible to include BLOCK, FMA and WORK_CENTRE boundaries in the one coverage, thus the new FORMB100 coverage was created making the original BLOCK100 coverage redundant. The BLOCK100 coverage will be archived in order to retain the compartment boundaries which could be used as a guide for collecting compartment boundaries at 1:25 000. Unfortunately the arcs in BLOCK100 did not contain any attributes. Ideally these arcs should have been re-retrieved from the base coverages so that the arc attributes could be maintained but due to time constraints this was not possible. As a result, the following FMAs in the FORMB100 coverage contain very few coded arcs: North-East and Benalla-Mansfield. The arcs in Central- Gippsland FMA contain AS2482 coding but very few SOURCED and SOURCEA coding. While compiling the FORMB100 coverage, several new blocks were created and some block numbers were changed. The new blocks include: Darraweit, Werribee, Modewarre, Teesdale, Bannockburn, Balliang, Werribee Gorge, Myrniong and Bullengarook in the Midlands FMA and Wallan in the Central FMA. Details of any changes can be found in the file: Forest Management - Block Standardisation - BLOCK1000/100/25 (file 94/1410).<P>FMA100 and BLOCK100 layers will be replaced by this single layer.<P>FORMB100 Layer Description1 Relationship to other Datasets: Some features in this layer may be derived from other layers such as SHIRE500. Current Design Issues: FMA500 must differentiate between individual forest management areas. Related Documents: None

Statement

Dataset Source: Original boundaries of FROMB100 were derived from the VICBASE SHIRE500, ROAD500, HYDRO500, REGION500 where possible and remaining boundaries were digitised from the existing map held in Drafting Services (G-1769). Linework has been generalised with a weed tolerance of 500 metre to reduce layer size and for ease of transfer into SDE. Dataset Originality: Primary
