We ran a two day search scenario this weekend, and I attempted to refine our usage of MapSAR. I ran across several problems (human error more than anything) which I am working on. However, there was one concept which was presented to me which is a departure from the way I have done things for years in ArcMap. When it comes to downloading GPSrs, storing the data, and latter displaying it, I have always used DNR GPS. This has always been presented to me as the standard in my experience with SAR and FIRE Incident Mapping (at least for the agencies I have communicated with). A self proclaimed "Computer Hacker" on the Team thinks it simpler to just use Windows File Explorer to copy the GPX file out of the GPSr (Garmin E-Trex Units, in our case), past it into the MapSAR GPS File, and rename it using our naming convention (date_operationalperiod_teamname_membername_track). It does work, yet I am imagining a number of non-ideal conditions under which I would need DNR GPS. Can anyone provide sound reasons why this "Hackers" method would not work for you?
