Dean Straw recommended the SRTM (Space Shuttle Topography Mission) 
90 meter data.  He has a draft of the HFTA operating directions 
that reference an updated microDEM that will work with the SRTM 
data.  Here is the relevant paragraph: 

 > Dr Peter Guth, author of MicroDEM, has fixed versions of MicroDEM 
 > after June 6, 2009, to work correctly with SRTM input. You will 
 > have to go to the MicroDEM website to download the complete basic 
 > package, which is about 55 MB in size. After you have installed 
 > the basic version, you must then download the latest executable 
 > Microdem.exe, following instructions also on the site: 

Appendix A in Dean's latest draft operating instructions provides 
detail on generating terrain profiles using the STRM data with the 
updated version of microDEM.
