This layer contains depth information in gridded format captured by multibeam sonar in 2021 as part of HS75 - Approaches to Napier. The data was collected for Toitū Te Whenua Land Information New Zealand (LINZ) and for which the survey took place from 10 October to 14 November 2021. Data management and distribution is by LINZ. Data comprises a gridded depth model as tif or ascii tiles in UTM projection. Vertical accuracy is +/- 0.3m (95%) Horizontal accuracy is +/- 1m (95%) Vertical datum is Approximate Lowest Astronomical Tide. The source data used to create the depth model may be of a higher resolution/density than the model. This data can be supplied on request.

Digital Surface Model (DSM) created from aerial photography of the wider Kaikōura region captured in the flying season of 2014-2015 captured by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany,0632, New Zealand. Coverage encompasses North Canterbury and Marlborough regions. The dataset comprises: Digital Surface Model (DSM) supplied at 2m resolution (2.00 m GSD) and 0.6 m point cloud (0.60 m GSD). The above is supplied in terms of New Zealand Transverse Mercator (NZTM) 2000 map projection and NZVD2016. The DSM has been adjusted and corrected to account for tectonic deformation associated with the 2016 Mw 7.8 Kaikōura earthquake, New Zealand (Massey et al., 2020) using an InSAR deformation model (Hamling et al., 2017).
