Abstract |
The pre-1750 and extant Forest Ecosystem maps of the Western sub-region comprise a number of different Generalised Additive Models (GAMs) and interpreted API and soils data. Within the extant vegetation area, expert botanists developed the map by assigning API polygons to vegetation groups, determined by an ecological classification process using PATN software. On cleared land, a combination of soils, GAMs, and classified site data was used to assign vegetation groups to distinct topographic and soil patterns. This hybrid expert and modelling approach was approved and signed off by a review team of expert botanists including two independents, one NPWS representative and one SFNSW representative. Seventy-six distinct ecosystems have been mapped in the pre-1750 map for this sub-region. The extant map was derived from the pre-1750 map by cutting it to the extant vegetation. The extant vegetation layer incorporates the vegetated API polygons from the CRAFTI project, RN17 mapping, and remnants. Seventy-two distinct ecosystems have been mapped in the extant map for this sub-region.

Lineage |
Extant vegetation was mapped for the Western sub-region of the Southern CRA area, using a multi-stepped approach. The pre-1750 vegetation map was compiled first using the procedure described below. That layer was then cut with a mask of extant vegetation derived from the Aerial Photograph Interpretation layer API remnants layers, and the Eastern Bushland Database for a small section not covered by API mapping. The coverage of existing vegetation was derived by converting to grid all API codes other than plantations (P and PP), excluded areas (EX), bare ground (A) and exotic forest (CV). |

Explanation |
The spatial data coverage is complete for the entire set. Each spatial element is attributed. Attribute verification is incomplete. |

DQ Conceptual Consistency |
|
Explanation |
Logical consistency tests were performed on all layers used in the modelling process. These included checking for consistency in origin and geo-referencing between layers. Botanical experts checked the spatial extent and distribution of each vegetation unit separately, as part of a check for logical consistency. |
DQ Topological Consistency |
|
Explanation |
Checked for missing attributes All attributes were checked |
DQ Absolute External Positional Accuracy |
|
Explanation |
The derived forest ecosystem type layer is georeferenced. Precision with respect to linear features: 10m to 30m. Positional accuracy estimate determined from comparisons with Landsat imagery, geo-referenced to level 10. |
DQ Non Quantitative Attribute Correctness |
|
Explanation |
The attribute of this dataset is the forest ecosystem type, which is defined as any group of tree-dominated stands which possess a general similarity in composition and character. There are approx. 200 forest ecosystem types identified and described. A subset of these vegetation types was found in the Western sub-region. Spatial units were attributed as described in the Lineage section of this metadata statement. While the experts and field assessors undertook a limited accuracy assessment, it is not possible to give a percentage value of how well the attributes conform to the classification method. A more detailed assessment will be provided in the final project report. Modelled forest ecosystem types were given a reliability code, rated from 1 (high) to 5 (low). |
