This metadata record covers a series of soil and land resource maps in the Alice Springs region from surveys conducted between 1976 and 1991. This mapping covers 43 pastoral leases some of which are now Aboriginal Land Trusts. The mapping and accompanying reports were published to provide information and advice on how pastures could be managed to optimise productivity in the long term. In most cases, the datasets and accompanying reports aim to refine the original land system mapping published by Perry et.al. (1962) and provides general descriptions of the landscape and vegetation. All mapping was originally published in hard copy format only and digitised into a GIS polygon spatial format between 2013 and 2018. The pastoral properties covered are listed below; Aileron, Alcoota, Allambi, Amburla, Bond Springs, Bushy Park, Central Mt Wedge, Coniston, Deep Well, Derwent, Dneiper, Erldunda, Hamilton Downs, Henbury, Huckitta, Jervois, Jinka, Kulgera, Lilla Creek, Lyndavale, Maryvale, Milton Park, Mt Cavenagh, Mt Denison, Mt Ebenezer, Mt Riddock, Napperby, Narwietooma, New MacDonald Downs, Numery, Old MacDonald Downs, Owen Springs, Palmer Valley, Pine Hill, Ringwood, Suplejack, Todd River, Umbeara, Undoolya, Utopia, Waite River, Woodgreen (Atartinga) and Yambah.
