Land Types of the Southern Part of the Northern Territory

VERSION 3 - Published March 2017 This polygon spatial dataset provides information on land types over the southern part of the Northern Territory, giving land type boundaries and describes their dominant landform, soil and vegetation. This is a cumulative mapping project that is under development on a region by region basis. The current dataset, Version 3, containing the regions of Barkly Clay Plains, Davenport Ranges, Elliott Ranges, Tennant Creek Sandplains and South Sturt & Gulf Fall was published in March 2017. This dataset supersedes the information published in July 2015 (Version 1. Barkly Clay Plains) and April 2016 (Version 2. Regions excluding South Sturt & Gulf Fall). This dataset is mapped at a nominal scale of 1:250,000. In general, each land type is based on one or more components of one or more land systems mapped in the amalgamated dataset SOUTH_1M, (Land Systems of the Southern Part of the NT) which is in turn based on the original land systems mapped and described by CSIRO in the 1940s and 1950s. The description of landform, soil and vegetation for each land type is based on the information contained in the original CSIRO reports. In addition, where available, information also incorporated descriptions from finer scale land unit surveys if they occurred within the mapping boundaries and vegetation site information and/or road note information if it existed over the area. The polygon boundaries are derived from remotely sensed imagery with pixel resolution of approximately 30m. The boundaries were created using an automated segmentation process that groups like-pixels into polygon segments. These segments were subsequently classified into land types. CAUTION: Although field information has been collected, the final dataset has not been validated. Users are advised that attribute accuracy varies over the study area.
