GEODAS-NG Software for MS Windows®
National Geophysical Data Center's GEODAS-NG (GEOphysical DAta System - Next Generation) software suite can be used for various NGDC downloaded data, including Marine Trackline Geophysics, NOS Hydrographic Surveys, Coastal Relief Model, ETOPO1 Gridded Elevations and Great Lakes Bathymetry. 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.
Desktop Windows Software
Click to install or update the GEODAS-NG Software Ver 1.0.04.01. See readme.txt for install instructions. For legacy GEODAS CD/DVD users only, you can update your software (for a limited time) only with GEODAS DVD Software Update Ver 220.127.116.11
NGDC has moved to using the GSHHG High-resolution Geography Database for World Shorelines and Political Boundaries. Click to download Version 2.2.2 GSHHG Shorelines and WDBII Rivers and Political Boundaries in ESRI Shape File© format. GEODAS software (see Desktop Windows Software above) 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 Shape File© formatted shoreline datasets.
Users who want the legacy GEODAS Coastlines files (also works with GEODAS-NG software) can download the GEODAS Coastlines
GEODAS Software application Grid Translator 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 Shape Files
GEODAS-NG Software application Hydro-Plot can be used to directly view contoured data in ESRI Shape File format. NGDC provides contours via various types of data, including Great Lakes Bathymetry contours.
GEODAS Exchange Formats MGD-2000
GEODAS-NG Software applications and many non-NGDC sites often use a set of data exchange formats developed at NGDC, collected as GEODAS MGD-2000 Formats. Formats included are:
For legacy GEODAS CD/DVD software, update software only with GEODAS DVD Software Update Ver 18.104.22.168
