Description:
Abstract:
This raster file represents an interpolated surface of the Mean Higher High Water (MHHW) for the California coastline (excluding the San Francisco Bay). The raster is interpolated from data for 12 NOAA tide stations along the coast.
Purpose:
To generate a surface elevation for MHHW to view the extent of land that is inundated on a near daily basis but not permananently inundated.
Supplemental_Information:
The station locations and tide data for all NOAA operated tide stations is available from NOAA in non-spatial format from the website: <http://tidesandcurrents.noaa.gov/station_retrieve.shtml?type=Tide+Data>

Process_Step:
Process_Description:
A buffer was created around the California coastline of 10 kilometers
Process_Step:
Process_Description:
Elevation data (attributes as Z-values) for the CA_Tide_Stations.shp were converted from floating point (meters) to integer (centimeters) to speed processing time and minimize storage space.
Process_Step:
Process_Description:
Using the buffered coastline polygon as a mask (limiting extent of raster), the "surface" of MHHW elevation was interpolated between the tide station points (CA_Tide_Stations.shp) using the Inverse Distance Weighting tool, with a power of 1. The elevation value was derived from the attribute of MHHW as a Z-value (NAVD88 centimeters).
Logical_Consistency_Report: The dataset is topologically correct.
Completeness_Report: Data set has been visually inspected.
Attribute_Accuracy:
Attribute_Accuracy_Report:
The tide station data is derived directly from the NOAA tide information available online at: <http://tidesandcurrents.noaa.gov/station_retrieve.shtml?type=Tide+Data>. For attribute accuracy refer to the website.
The interpolated surface is derived from computer automated processes and tidal elevations may vary depending on location. No ground-truth was carried out nor were oceanographers or coastal engineers consulted.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Locations of tide stations are provided in Decimal Degrees, which we projected into WGS 1984 using ArcGIS. These stations were used to interpolate the surface elevation of MHHW between stations
