Nullamanna National Park Vegetation 2008 VIS ID 4751
공공데이터포털
Nullamanna National Park vegetation mapping was undertaken by Dr John T. Hunter in 2008 by contract for the NPWS Northern Tableland Region. Nullamanna NP is a small reserve of under 300 ha that occurs within the North Western Botanical District and the Nandewar Bioregion. The reserve lies closest to Kings Plains National Park. The vegetation of Nullamanna National Park is described and mapped (scale 1:25 000). Five communities are defined based on classification (Kulczynski association). These five communities were mapped based on ground truthing, air photo interpretation and landform. Much of the reserve is characterised by Callitris endlicheri, Eucalyptus dealbata, Eucalyptus crebra, Eucalyptus caleyi and Eucalyptus moluccana with a shrub layer of Leucopogon muticus, Notelaea microcarpa, Melichrus urceolatus and Leptospermum brevipes with a ground layer of Cymbopogon refractus, Cheilanthes sieberi, Austrodanthonia caespitosa, Aristida ramosa and Panicum effusum.

Vegetation mapping for Winburndale Nature Reserve Mt Horrible Addition VIS ID 3986
공공데이터포털
Survey and mapping was commissioned by NPWS Western Branch Macquarie Area, Bathurst office. Six floristic quadrats were sampled to further describe the vegetation communities. Walked transects and topographic maps were used to delineate vegetation boundaries. The author correlated map units to vegetation communities described in the original Winburndale NR vegetation report (ERM Mitchell McCotter 1996) and allocated them to NSW Vegetation Classes and Formations (Keith 2004) for fire management purposes. Hardcopy maps were digitsed in the Dubbo NPWS Western Branch office. Subsequent to the final report, NPWS staff have corrected correlation errors and re-assigned some map units to the NSW classification (Keith 2004). Mt Horrible (addition to Winburndale NR) mapping supplements existing mapping for Winburndale NR [Vegetation descriptions in: ERM Mitchell McCotter Pty. Ltd. (1996) Bathurst vegetation survey for NSW National Parks and Wildlife Service: Bathurst District covering Winburndale NR, Nangar NP, Conimbla NP and Weddin Mountains NP. NSW National Parks and Wildlife Service, Bathurst. Mapping undertaken by Roger Lembit under contract to NPWS Bathurst District office in 1997 due to inadequacies in ERM mapping.]
Geospatial data for the Vegetation Mapping Inventory Project of Amistad National Recreation Area

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The TOP 2015 imagery was mosaiced and manipulated using image processing and segmentation techniques (e.g. unsupervised image classification, normalized difference vegetation index, etc.) to highlight any subtle vegetation signature differences. All of the preliminary results were evaluated for usefulness and the best examples were first converted to digital lines and polygons, were next combined with other relevant AMIS GIS layers (such as the roads network), and the results were used as the base layer for the new AMIS vegetation mapping effort. Building off the base layer, all relevant lines and polygons were exported as shapefiles and converted to ArcGIS coverages. The resulting coverages were run through a series of smoothing routines provided in the ArcGIS software. Following the smoothing, all digital line-work was manipulated to remove extraneous lines, eliminate small polygons, and merged polygons that split obvious stands of homogeneous vegetation. The cleaning stage was considered complete when all resulting polygons matched homogenous stands of vegetation apparent on the TOP 2015 imagery. At this point, the mapping shifted to manual techniques and all vegetation lines and polygons were visually inspected and manually moved, edited and/or updated as needed.

Maryland National Park Vegetation 2006. VIS ID 4745

Maryland National Park vegetation mapping was undertaken by Dr John T. Hunter in 2006 by contract for the NPWS Northern Tableland Region. Maryland NP lies within NSW approximately 20km north east of Stanthorpe, Qld and comprises some 2,284 ha of lands. Parts of these reserved lands were once under the control and management of State Forests, while other more recent additions were free hold land used for grazing enterprises. The reserve lies along the NSW-Qld border and is half within the Northern Tablelands and half in the North Coast Botanical Divisions. The lands are incorporated entirely within the New England Tablelands Bioregion within the local government areas of the Parish of Marsh, County of Buller and Shire of Tenterfield. The vegetation of Maryland National Park is described and mapped (scale 1:25 000). Six communities are defined based on classification (Kulczynski association). These six communities were mapped based on ground truthing, air photo interpretation and landform. Almost all of the reserve is dominated by the Eucalyptus biturbinata, Eucalyptus campanulata and Lophostemon confertus. Much of the reserve has been disturbed in the past, particularly by Logging, clearing and grazing. The original mapping was recorded as VIS ID_457 and this version has the addition of PCT and fire veg classification fields. VIS_ID 4745
