July 2014 Topographic Data Release Notes.

Data Changes

To make the most efficient use of the resources available, the LINZ Topographic team is adopting a new technique for the update of LINZ Topo50 data. We're using what we're calling a 'HighVis' (high visibility) approach.
Where they are present, new roads (and road names), backcountry tracks & huts, schools and transmission line features are checked and updated. Changes to gazetted geographic names are also made.
For the remaining features, each sheet is scanned, and only features that stand out as being significantly different from the previous edition are updated. 
The types of changes will vary across the country.  
For example in some areas large tracts of land are being changed from forest to life-style blocks. In these areas the vegetation areas are updated and the new buildings and associated features added.  In other areas where the vegetation and building changes are minimal, the data remains as is.
Fences in the Topo50 dataset are a representative pattern that indicates general land use. With a HighVis approach these would rarely be changed.  However they were for BV24, Waipara where the fence pattern changed from rectangular to circular, altering the appearance of the land significantly and indicative of a change to dairy farming.
In this release sixty-seven sheets have been through the HighVis process; contours have been updated in the Stockton Mine area.
