This spatial dataset provides polygon information delineating the indicative extent of the area in which biophysical studies are proposed to be undertaken as part of the Strategic Regional Environmental and Baseline Assessment (SREBA) for the Beetaloo Basin. The polygon boundary defines the ecological domain within which impacts resulting from onshore gas development in the Beetaloo Basin could be reasonably expected to become evident. This has largely used geomorphic and hydrological data sources as surrogates for defining the extent of the study area. This dataset should be considered indicative of the final SREBA boundary. Further development of this boundary will be undertaken as the SREBA progresses.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownPOLYGON DATA - Polygon boundaries were delineated on Google Earth imagery with a variable positional accuracy of approximately 1.5m-40m (depending upon location)and rectified Sentinel-2 imagery data provided by the Queensland Department of Environment and Science with a geometric accuracy of less than 12.5 m (ESA, 2015). This level of accuracy is considered high to very high in the context of this study.0not knownAttribute values, as described in the Data Dictionary below, have been added to the polygon.0The polygon boundary was delineated manually in ArcGIS using a combination of satellite image and aerial photograph interpretation, published land and water resource information and expert knowledge to define the ecological domain within which impacts resulting from onshore gas development in the Beetaloo Basin could be reasonably expected to become evident. The study area boundary was interpreted from a range of historic land system and geological information with contemporary imagery and additional interpretation used to refine the concepts and identification of key geomorphic or hydrological features associated with the Beetaloo geological sub-basin and associated shale depocentres. Limitations associated with the scale or attribution of primary datasets associated with the interpretation of this ecological domain will be inherent within this derived dataset.
