NGDC (now NCEI) Exchange Formats
GEODAS-NG Software applications and many non-NCEI sites often use a set of data exchange formats (MGD-2000) developed at NGDC (now NCEI). Formats included are:
NCEI has moved to using the GSHHG High-resolution Geography Database for World Shorelines and Political Boundaries. GEODAS-NG software (see Desktop Windows Software below) works with GSHHG/WDBII.
GEODAS-NG Software (see below) Grid Translator application can be used view, revise, subset and re-format ESRI ASCII Raster grids and Binary grids. NCEI's ETOPO1 Global Relief, US Coastal Relief Model, Great Lakes Bathymetry, and other gridded datasets can be directly imported. See NCEI's
Digital Elevation Model Discovery Portal for links to 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. NCEI 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 NCEI GEODAS-NG software is offered for users.
