This spatial dataset provides polygon information delineating land unit boundaries at a scale of 1: 25 000 and describes the dominant landform, soils and vegetation of the Ti Tree Basin Area, Northern Territory. The study area is comprised of 7 separate sections and covers 135 km2 and located south of the Ti Tree township via the Stuart Highway and Cavenagh Road over NT Portions 3636, 725 and 6152. The primary purpose of the investigation was to map, describe and evaluate soil landscapes to inform future irrigation development in an area with identified potential for groundwater extraction. Core landform, soil and vegetation attributes attached to the land units are included with the spatial dataset. CAUTION: Map unit boundaries were derived using satellite imagery in association with a digital elevation model, geological and topographic data. Landform, soil and vegetation field assessments conform to national standards and support mapping at a scale of 1:25 000. When assessing specific areas within the mapping it is recommended a site inspection is undertaken to establish unmapped variation and confirm mapping accuracy on the ground. The mapping does not indicate, imply or ascertain the likelihood of groundwater availability or the granting of appropriate water extraction licensing needed to satisfy the irrigation requirements of the potential agricultural development options needed.
