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 Wildman River Area, Northern Territory. The study area covers 343km2 and is located approximately 100km south-east of Darwin via the Arnhem Highway and is situated between the Mary River and Kakadu National Parks. 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.
