In addition, Fugawi Global Navigator and Fugawi Marine ENC version 4.0.x or higher now also support Fugawi Elevation Library (.FEL) format elevation and bathymetric files. FEL files are avaiable for the entire world and are included as part of the Fugawi Data Packs.

Shuttle Radar Topography Mission (SRTM)

In 2000 the Space Shuttle Endeavor measured the elevation for the world between 56 degrees south and 60 degrees north. Preliminary data have been released with 3 arc second spacing (about 90 meters). These data are supported by Fugawi beginning with version 3.1.2.548.

• Go to http://srtm.usgs.gov/ for information on downloading the data
• In Fugawi, go to Forms|Elevation Library. Select the "HGT SRTM 3 second" option and click on the "+" key to add the new data to your library. You will be prompted to supply the parent folder where the data is contained.

The "Finished" SRTM data is now available at http://edc.usgs.gov/products/elevation.html

USA National Elevation Data (NED)

NOTE: This format is supported in version 3.04.243 and later. The NED data set with 30 meter spacing is available in BIL format on the USGS web site. Instructions for downloading NED data (It appears that Netscape does not work properly with the site. Use Internet Explorer):

• Go to
  http://seamless.usgs.gov.
• Click on "View and Order United States Data"
• Click on “Define Area by Coordinates” on left panel.
• Enter latitude and longitude. If you order less than 10 mb of data, it is available free via FTP. For example .5 degree x .5 degree = 6.5mb
• Click on "Select Area"
• Click on "Modify Data Request"
• Uncheck all boxes except "NED".
• Next to NED change the Data Format to "BIL"
• Click on "Save Changes and Return to Summary"
• Click on "Download"
• Unzip the file using winzip. (Winzip is available at www.winzip.com.)

In Fugawi, go to Forms | Elevation Library. Select the "BIL" option and click on the “+” key to add the new data to your library. You will be prompted to supply the parent folder where the data is contained.

Worldwide NIMA DTED® Digital Terrain Elevation Data

The US Department of Defense offers world-wide elevation data in DTED format. The data is available in different resolutions, with Level 0 being the lowest level of resolution. Level 0 data is spaced at 30 seconds of latitude and longitude (about 900 meters, depending on latitude). The Level 0 data is available over the internet for civilians as follows:

• Go to
  http://geoengine.nima.mil/geospatial/SW_TOOLS/NIMAMUSE/webinter/rast_roam.html/
• Click on the map to zoom in to a reasonable-sized area (for example the size of Germany).
• Click on the Download/Order tab.
• In the DTED section click on Download.
• Click on Build File for Download
• When the sceen says "Download Your Zip File" and "Your File is Ready", click on the file name to download.
• Unzip the zip file (see www.winzip.com for a program to unzip the file). Place the unzipped files in a new folder with a name that will help you identify the region. Be sure there is no dmed. file, text folder, or dted folder already in this destination folder. If any of these files/folders exist in the destination folder, they will be overwritten and your DTED® software tools may not perform properly. Do not alter the folder structure once the data have been unzipped.
• In Fugawi go to Forms | Elevation Library
• Set the type of file to DTED.
• Click on the "+" button to add the new data to your elevation library.
