An accumulation of boulders, stones or other debris carried and deposited by a glacier. Data Dictionary for moraine_poly: http://apps.linz.govt.nz/topo-data-dictionary/index.aspx?page=class-moraine_poly This layer is a component of the Ant50 map series. This is the topographic mapping carried out at 1:50,000 scale by LINZ within the Ross Dependency, Antarctica.

Ice stream; a current of ice in an ice sheet or ice cap that flows more rapidly than the surrounding ice,usually flowing to the ocean or to an ice shelf and not constrained by exposed rock. Data Dictionary for ice_stream_cl: https://docs.topo.linz.govt.nz/data-dictionary/tdd-class-ice_stream_cl.html This layer is a component of the Ant50 map series. This is the topographic mapping carried out at 1:50,000 scale by LINZ within the Ross Dependency, Antarctica.

This layer contains the DEM for LiDAR data from the Kaikoura area captured in 2012. The DSM is available as layer [Canterbury - Kaikoura Lidar 1m DSM (2012)](http://data.linz.govt.nz/layer/3545). The index tiles are available as layer [Canterbury - Kaikoura Lidar Index Tiles (2012)](http://data.linz.govt.nz/layer/3570). The LAS point cloud and vendor project reports are available from [OpenTopography](http://opentopo.sdsc.edu/datasets). Lidar was captured for Environment Canterbury Regional Council by Aerial Surveys in 2012. Note that this capture was prior to the significant vertical and horizontal displacements from the 2016 Kaikoura earthquakes. The datasets were generated by Aerial Surveys and their subcontractors. The survey area includes the Kaikoura township area and adjacent coastal strips. Data management and distribution is by Land Information New Zealand. Data comprises: •DEM: tif or asc tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout •DSM: tif or asc tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout •Point cloud: las tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout Data was collected at >1 pulse/square metre pulse density. Attributes include: -Elevation -Intensity values -Return number -Adjusted GPS time -Classification Vertical accuracy specification is +/-0.2m (@ 95% confidence) Vertical datum is NZVD2016
