GEODAS-NG Desktop Software
for use with Downloaded Trackline Geophysical Data
Please send any comments to
|NGDC's GEODAS-NG (GEOphysical DAta System - Next Generation) desktop software tools can be used for working with data downloaded from NGDC's trackline web presence, especially NGDC-developed downloaded formats. While this software suite is expected to work well for some time, support in the form of updates and other changes may not be available after late 2014. It may be useful to explore other commercial and open-source tools to determine if they meet your needs.|
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.
See NGDC's Shoreline/Coastline Resources page for links to GSHHG/WDBII and to other ESRI shapefile formatted shoreline datasets.
Users who want the legacy GEODAS Coastlines files (also works with GEODAS-NG software) can download the GEODAS Coastlines
For more information about Coastlines at NGDC please contact
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.
NGDC's WCS Grid Extraction Tool replaces the online GEODAS grid translator, enabling creation and download of custom grids of bathymetry/topography.
For more information about Gridded Datasets at NGDC please contact
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.
The GEODAS-NG (GEOphysical DAta System - Next Generation) software suite can
be used for NGDC downloaded data. Other datasets can also benefit from this comprehensive software package. The renamed GEODAS-NG software represents a somewhat different direction than deprecated GEODAS DVD-focused software. GEODAS-NG software does not support the legacy GEODAS CD and DVD datasets. Rather GEODAS-NG will focus directly on downloaded data files in various formats.
Download GEODAS-NG Software Ver 1.1.3 (see readme.txt for installation instructions).
For legacy GEODAS CD/DVD users only: You can update your software using (only) GEODAS DVD Software Update Ver 22.214.171.124. GEODAS DVD Software can co-exist with the newer GEODAS-NG Software.
