Service Description: Foreshore sediment type – provides a
description of the type of sediment and grain size of material making up
the beach. This variable has 11 attributes such as gravel, sand and
mud.
The geomorphic variables were sourced from the New Zealand coastal type
classification scheme and GIS mapping procedures that were previously
created for Coastal Explorer using advice from expert panels including
regional council staff, knowledgeable locals, university staff and
consultants from throughout New Zealand. The coast was mapped and
referenced against panel knowledge using information from a wide variety
of sources including: 1:50,000 topographic maps, aerial photographs,
Google Maps and Google Earth, RNZN hydrographic charts, various
publications and reports, New Zealand Land Resources Inventory (NZLRI),
the National Land Cover Data Base (LCDB), and the Estuarine Environment
Classification database. In assembling the coastal and beach type
information, site visits were made to many beaches to obtain information
that could not be collected from existing sources, and parts of the
coast were flown by light aircraft to obtain oblique aerial photographs. https://gis.niwa.co.nz/arcgis/rest/services/COAST/NZ_Coastal_classification_Foreshore_sediment/MapServer/
