Mitchell landscapes (version 3)

This dataset (version 3) supersedes the previous version of the NSW Landscapes (Version 2) ANZNSO208000229. Version 3 includes a revision of the polygon boundaries conducted in 2008. Revision corrected many alignment errors using SPOT 5 imagery as a reference layer. The revisions for Version 3 have resulted in significant alterations to Landscape boundaries in some regions. See associated technical report 'ELA 2008 Editing Mitchell Landscapes'. Version 2 maps were constructed from existing data and have a strong geologic, geomorphic and pedologic base. They do not include field validation/original mapping. Scale and reliability was constrained to 1:250,000 scale by the availability of suitable state-wide maps, although some source data (air photos/maps) were more detailed. A transect of map sheets was compared with other data during the mapping, it is believed reasonable product consistency has been attained. Details on the methodology, limitations and constraints in the devlopment of the original dataset are contained in P.B.Mitchell (2002) NSW Ecosystems Study: Background and Methodology (Unpublished).
