The Waimakariri District Council have made available a five page report consisting of aerial maps of Kaiapoi. Each of the five maps shows consequences of the earthquakes in terms of liquefaction, the severity of damage over the area, building damage ratio, height differences (changes to land height) between 2003 and 2011, and ground surface elevation in March 2011.
It can be downloaded as a PDF file from here. A wide range of local information can be found on the Waimakariri District Council's New Foundations website here.
Similar information for Christchurch, but not at the level of detail in the Kaiapoi images (which is equivalent to suburb level), was part of the zoning presentation on the 23rd of June. Prepared by Tonkin & Taylor, it is available as a PDF file here. Also available are PDF copies of the presentations for the areas covered by the Waimakariri District Council (the same report as mentioned above) and Christchurch City Council (here).
For those unfamiliar with the term LIDAR, and what LIDAR is, the following is from the United States Geological Survey:
LIDAR (Light Detection and Ranging) is an optical remote sensing technology which measures properties of scattered light to find range and/or other information of a distant target.
The prevalent method to determine distance to an object or surface is to use laser pulses.
Similar to radar technology, which uses radio waves instead of light, the range to an object is determined by measuring the time delay between transmission of a pulse and detection of the reflected signal.
For those who want to know more than enough about LIDAR, check out the USGS LIDAR website here.
