Processing Steps |
- 2014-04-05T00:00:00 -All datasets obtained by NGDC were transformed to common horizontal and vertical datums
of WGS84 geographic and Mean High Water, respectively, using proj4, gdal and VDatum.
They were also converted to common file format, ESRI point shapefiles, for visualization
and inspection.
- 2014-06-15T00:00:00 -Datasets were visually inspected with ArcGIS for identification and editing of data
anomalies. Datasets were then compared with overlapping datasets to ensure data consistency.
- 2014-06-16T00:00:00 -Existing bare-earth DEMs were clipped based on the extents of newer lidar data. The
DEMs were converted to xyz data for use in gridding.
- 2014-07-01T00:00:00 -Lidar data was filtered and edited to 'bare-earth' using custom tools and Virtual
Geomatics. Water surface returns were manually removed from the dataset.
- 2014-07-15T00:00:00 -Lidar data files were converted to xyz data for use in gridding.
- 2014-07-16T00:00:00 -xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a
1/3 arc-second grid that interpolated to fill empty cells. Points extracted every
10 meters along the coastline were also included to ensure that the bathymetric grid
reached zero at the coast. The resulting Arc ASCII grid was clipped to the coastline
to remove values over land.
- 2014-07-16T00:00:00 -xyz files of the topographic data were surfaced using GMT's 'surface' tool onto a
1/3 arc-second grid that interpolated to fill empty cells. Points extracted every
10 meters along the coastline were also included to ensure that the bathymetric grid
reached zero at the coast. The resulting Arc ASCII grid was clipped to the coastline
to remove values over water.
- 2014-07-17T00:00:00 -xyz files for each input dataset were gridded using MB-System's 'mbgrid' tool, which
utilizes a high-tension spline interpolation method to fill grid cells with no input
elevation values. Preferential weighting was given to more recent, higher-accuracy
datasets.
- 2014-07-20T00:00:00 -The DEM was quantitatively evaluated by comparing with source datasets and with elevation
values extracted from NGS geodetic monuments. It was visually evaluated by converting
to UTM-zone coordinates (units of meters horizontally and vertically) and then creating
a slope grid to identify gridding artifacts in the DEM.
