Description
The Onshore Petroleum Infrastructure Dataset provides spatial data on land clearing activities and infrastructure development associated with the Northern Territory's onshore petroleum industry from 2019 to the present. The data identifies the approved Environmental Management Plan (EMP) the clearing occurred under and the use of the cleared area. Currently, the dataset contains site-specific information for infrastructure within the Beetaloo Sub-basin, with plans for gradual expansion to encompass additional areas in the NT. The dataset documents land use changes related to exploration and production, offering insights into cumulative environmental impacts and industry growth. The dataset is regularly updated and made publicly available. Users can view and export the data via NR Maps [https://nrmaps.nt.gov.au/nrmaps.html] under the Onshore Petroleum Infrastructure.

Data Quality
Lineage:The dataset consists of polygons and polylines representing cleared areas associated with the Northern Territory onshore petroleum industry. The geometries of these spatial files have been preserved in their original form as submitted by the various interest holders. The one exception is POLY_002 that was corrected using GIS tools due to a significant overshoot of the actual clearing footprint. The processing undertaken by DLPE involved the compilation of the individual datasets into a consolidated shapefile and the standardisation and population of attribute tables to support data usability and consistency. The dataset consists of shapefiles submitted to the Department from 2019 onwards by various interest holders. While the exact methods used by contributors are unknown, GIS technology was utilized for data acquisition and processing. The dataset is structured to reflect the spatial extent of land clearing and infrastructure development, ensuring accurate representation of industry impacts over time.
Positional Accuracy:The spatial accuracy of the polygons and polylines depends on the methods employed by various interest holders for data collection, which are assumed to involve GIS technology. Positional accuracy is likely influenced by the resolution of source imagery and the precision of digitization. While specific accuracy metrics are unavailable, the dataset is intended to provide a reliable representation of activities undertaken and cleared areas within the Beetaloo Sub-basin, with ongoing updates to include additional regions.
Attribute Accuracy:The dataset includes attributed spatial features that correspond to documented land clearing areas and infrastructure development within the Northern Territory's onshore petroleum industry. The original spatial data attributes submitted by the various interest holders were inconsistent, incomplete and lacked standardisation. As a result, the attribute data in its original format was not retained. Instead, a new standardised attribute table was created and applied to the dataset. These new attributes were designed to support user understanding and navigation of the data. Users should be aware that the current attributes were generated by DLPE for organisational and viewing purposes. The dataset undergoes regular updates to enhance completeness as new information becomes available.
Logical Consistency:Topological validation of the data revealed the presence of overlaps, gaps and silvers between polygons. With the exception of POLY_002, these issues were not corrected as the data was received by various interest holders and the intent behind these spatial configurations is not known. POLY_002 was corrected due to a significant overshoot in the polygon which did not accurately represent the cleared area. Editing the entire dataset without understanding its original purpose could compromise its integrity or meaning. Therefore, the configuration of the dataset has been retained in its original form, and users are advised to apply their own quality checks if topological precision is required for their use. As new data becomes available, communications with interest holders will aim to address these issues and improve consistency and accuracy. Additionally, several polygons and polylines may potentially overlap, this is due to overlapping land clearing purposes. For example, land that was originally cleared for seismic acquisition lines may now partially overlap with an access track or well pad etc. Multipart polygons are also present in the dataset, these gaps in the polygons show areas that were not cleared. Generally, they represent a patch of significant vegetation or trees that were avoided in the clearing process.
