for use with Downloaded Trackline Geophysical Data
NGDC Exchange Formats
GEODAS-NG Software applications and many non-NGDC sites often use a set of data exchange formats (MGD-2000) developed at NGDC. Formats included are:
Coastlines at NGDC
NGDC has moved to using the GSHHG High-resolution Geography Database for World Shorelines and Political Boundaries.
Download the latest GSHHG Shorelines and WDBII Rivers and Political Boundaries in ESRI shapefile format.
GEODAS-NG software (see Desktop Windows Software below) works with GSHHG/WDBII. GEODAS application Coastline Extractor allows sub-setting GSHHG/WDBII (and many other shoreline data sets) by area, resolution, etc.
GEODAS-NG Software (see below) Grid Translator application can be used view, revise, subset and re-format ESRI ASCII Raster grids and Binary grids.
NGDC's ETOPO1 Global Relief, US Coastal Relief Model,
and Great Lakes Bathymetry and other gridded datasets can be directly imported.
See NGDC's Digital Elevation Model Discovery Portal for links to NGDC's bathymetry gridded datasets.
Contour Data Shapefiles
GEODAS-NG Software (see below) Hydro-Plot application can be used to directly view contoured data in ESRI shapefile format. NGDC provides contours via various types of data, including Great Lakes Bathymetry contours.
GEODAS-NG Desktop Windows Software
While there are many commercial and non-commercial software packages that exist
for further processing and visualizing trackline data, the NGDC GEODAS-NG software is offered for users.
