Alternative title(s)

Abstract

This dataset represents fine-scale floristic vegetation mapping within eastern freehold lands of the Bellingen Local Government Area. Vegetation has been categorized into communities, classes and formations, with the composition of respective vegetation species identified. Mapping was conducted by vegetation mapping ‘experts’ (NSW Office of Environment and Heritage) between September 2011 and December 2012, and was based on 3-D PLANAR modelling, aerial photography interpretation and field floristic assessment.

Purpose

The dataset was primarily designed to identify vegetation communities to support Koala Habitat modelling and identification of potential EEC's for display and interpretation at scales no finer than 1:5,000. Non-natural areas, devoid of vegetation, have not been mapped. Various levels of attribute confidence are identified within the data's 'Reliability' attribute field. Users are reminded that the layer represents a model, and should only be regarded as an interpretation or prediction of real-world phenomena.

Lineage

Funding was made available for a Koala habitat study under the Saving out Species ‘iconics’ funding. The Koala habitat study required accurate and fine scale vegetation data to underpin the modelling of primary and secondary habitat values. The opportunity existed to upgrade both the linework and classification of the existing forest ecosystems map to match the current OEH standards in mapping and classification. This layer utilises improvements in aerial imagery (ADS40), an upgraded classification (NSW Vegetation Classification and Assessment) and developments in 3D stereo mapping environments. The study was designed in response to available funding and koala study priorities. The study area was tailored to the needs of the Koala Habitat study and covered 24 326ha of lowlands, coastal hills, escarpments and alluvial plains in the eastern part of the Bellingen LGA. Source data for this layer has two components, the floristic field based site data and the other being high resolution aerial photography and LiDAR. SITE DATA. At the beginning of the mapping study, 224 full floristic flora survey plots from previous studies occurred in the Bellingen LGA, with an additional 82 rapid floristic sites. However, in the study area (a priority subset of the LGA) there were 8 full floristic and 23 rapid (mostly canopy species) sites. This bias in the existing data made the initial stages of the project difficult and focusedon collecting field data to support the mapping. Thanks to participating landholders an additional 874 field API rapid data sites were collected during the project (canopy species and some lower strata, PCT id sites) on non-public lands. AERIAL PHOTOGRAPHY (ADS40) and LiDAR. The NSW Land and Property Information (LPI) captures airborne ADS40 4-band digital imagery at 50cm resolution for most of NSW. The Macksville and Nambucca (April 09) 1:100k tile, the Dorrigo (September 09) 1:100k and the Coffs Harbour (September 09) 1:100k covered the Bellingen LGA study area. Two levels of imagery were utilised for the project, the 4-band 2-dimensional orthorectified images and the Level 1 Rectified stereo image pair strips. The Level 1 data was used for 3-dimensional mapping in an ArcGIS stereo environment. LiDAR, also captured by LPI was utilised as 2D contextual data to help guide mapping decisions and to convert mapping data to 3D format. LiDAR only covered the eastern portion of the LGA and thus ADS40 derived elevation data was used where LiDAR was absent. MAPPING PROCESS. Mapping was conducted by API/botanical experts in a stereo view workstation comprising of PLANAR monitors, ESRI ArcMap software and ERDAS Stereo Analyst software. The environment allows the direct delineation and attribution of polygons in 3D stereo view (Level 1 imagery) whilst simultaneously having a 2D context view and any number of additional datasets to guide mapping decisions. Interpreters used a detailed Bellingen LGA landcover layer as the starting point for each tile as an efficiency for the process. Interpreters had at their disposal all site data (31 sites) in 3D. Interpreters routinely collected field check points with GPS to help extrapolate across areas of difficult interpretability. A total of 874 check points were collected for the project where public access was permissible. The mapping was conducted at on screen at a range of scales but the final reference scale is deemed to be 1:5000. Linework was digitised using live streaming with a stream tolerance average of 5 metres ie a vertex every 5 metres. The study area was divided into 9 tiles for stereo mapping and the interpreters cross referenced each other whenever possible to help guide the consistency of mapping decisions. The tiles were stitched together in GIS and interpreters then reviewed the edges and remapped any inconsistencies. A final quality review of the stitched map was conducted by examining each community in isolation and reviewing it for errors and ecological distribution anomalies. This review process fed back in further refinements and edits. Overall, the linework is very accurate as it is based upon the Bellingen LGA land cover layer. Minimal discrepancies were found between 3D and 2D spatial accuracies
