Relative Age

The Statewide Forest Resource Inventory (SFRI) is a program of information collection and analysis of Victoria's native forests that supports statewide planning and management.

One SFRI product is SFRImap Database - a database of information on the eucalypt composition, structure and history of Victoria's forests.

SFRImap Database covers most of Victoria's forests on public land at a scale of 1:25,000.

Relative Age is a layer derived from SFRImap. It is SFRImap dissolved on the RELAGE attribute. Derived layers from SFRImap Database are complimented with the same metadata as the SFRImap layer.

Geospatial 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). Initial API audited using a "field based" approach using skilled auditors. Disturbance attributes (REGEN and TREAT fields) rely on the accuracy of disturbance information available. The SFRIMAP layer (since being derived from SFRI25VE) is to be used with data sets that are commensurate with the Victorian Government's "VICMAP" 1:25,000 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). Polygons that have the tile boundary included in their perimeter must have at least one vertex greater than 3 meters (ground units) from the tile boundary linework. Internal lines (lines away from the tile boundary must be mort than 10 metres (ground units) away from the next cover so that the maximum deviation between tile boundaries is less than 0.01 metres (ground units). These data limitations are more related to photographic interpretation factors. Any post-photodate intersections with logging history from log_{season} sees the SFRI linework take precendence where snapping has occurred with tile boundaries.
