<p>This layer contains depth information in gridded format captured by multibeam sonar in 2018 as part of HS65 - Cavali Passage (RNZN).<br>
The data was collected for Toitū Te Whenua Land Information New Zealand (LINZ) and for which the survey took place from 6 September to 27 October 2018. Data management and distribution is by LINZ.</p>
<p>Data comprises a gridded depth model as tif or ascii tiles in UTM projection.</p>
<p>Vertical accuracy is +/- 0.38m (95%)<br>
Horizontal accuracy is +/- 0.54m (95%)<br>
Vertical datum is Approximate Lowest Astronomical Tide.</p>
<p>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.</p>
