South Waikato District Data

This layer has been provided to identify the coverage of digitised and released historic aerial photos for Mainland NZ flown on behalf of the Crown between 1936 and 2005. The layer shows the extents of the aerial surveys released by LINZ under open license. The NZ Aerial Photo Footprints, Mainland NZ, (1936-2005) polygons layer shows the extent of each photograph in the survey and provide metadata for the individual photos.

See: www.flickr.com/photos/135346658@N08/albums for access to the photos. The photos are not downloadable from the LINZ Data Service. Please note that the process to make the scanned photos openly available is still under development, and the distribution mechanism may change. These first ten surveys are made available to showcase the content of the archive and what users can expect access to. Once we have established the long-term distribution mechanism LINZ’s goal is to periodically add surveys to this layer as they become available. We expect this distribution mechanism will be established near the end of 2015 and the next release of surveys will occur at that time.

The original data used to create this layer was compiled prior to 2000 and it is possible that some errors exist in the data fields. If you are aware of any inaccuracies, please contact LINZ: info@linz.govt.nz or +64 4 4600110.

This layer provides the extents of the data incorporated into an adjustment which has been completed as part of the Spatial Parcel Improvement (SPI) project. The SPI project aims to improve the accuracy of digital cadastral data in areas (primarily rural) where survey-accurate data does not currently exist. The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be at least several metres, as the SPI project targets areas where significant movements are expected.
