MSAM compatible GLOBE topographic data is available from the NOAA National Geophysical Data Center website. Just click on the map tile(s) that covers your area of interest and uncompress the downloaded data using WinZip. You must also download the globe.dat compressed file from this web site and save it to the same disk folder location as the GLOBE data.
MSAM compatible geographic data, i.e. political boundaries, hydography, roads, railroads, etc, provides a geographic reference framework for the display of the coordination contour data calculated by Appendix 7. You must download the NTIA Geo Data and save it to your hard drive, e.g. c:\NTIA Geo Data\.
