GLO Landscape Classification 20160929 v04

Abstract

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This dataset is a reformatted version of the input source dataset from which it is derived in that the source singleapart line shapefile has been dissolved into multipart geometry. So that in this version there is one record per riverine landscape class. This was necessary to meet the format requirements for the BAIP.

This dataset contains polygon and line shapefiles representing the Gloucester terrestrial (both a multipart and singlepart version) and riverine Landscape Classes respectively. The polygon landscape Classes are as follows.

Terrestrial (polygons)

Forrested Wetlands

Freshwater Wetlands

Rainforests

Dry sclerophyll forests

Wet sclerophyll forests

Saline wetlands

(Non-GDE) Native vegetation (with Keith Forms)

Plantation or production forrestry

Dryland agriculture

Irrigated agriculture

Intensive uses (includes mining)

Purpose

This dataset has been reformatted to make it suitable for ingestion into the BAIP.

Dataset History

GDE landscape classes derive directly from the source NSW OoW GDE layer's Keith Form attribute, though the "Riverine Forests" Keith form are combined with the "Forested Wetlands" LC and the "Mangrove Swamps" and "Saltmarshes" Keith Forms are combined to form the "Saline Wetlands" LC .

The remaining non-GDE terrestrial LC polygons are mainly sourced from the ACLUM catchment landuse from the PRIMARY V7 classification, and retain the source class names except that "1 Conservation and natural environments" is rename the "non-GDE Native Vegtation" LC. A further exception is the "Plantation and Production Forestry" LC. This is derived from the SECONDARY_V7 classification where:

"SecondV7" = '2.2 Production forestry' OR "SecondV7" = '3.1 Plantation forestry' OR "SecondV7" = '4.1 Irrigated plantation forestry'

The Riverine LC lines are derived directly from the Rivertypes source dataset

The line shapefile in the source dataset was dissolved on the lc_id, LC_Class and LC_Group fields to create a single, multipart record for each landscape class. The LC_km values were recalculated accordingly. The polygon shapefile is unchanged from the previous version as it was already a multipart shapefile but has be renamed as v04 to keep consistent with the set.
