IIRC, OpenTRAC was something going on in Australia. There was an 
offshoot SARTrac used for Search and Rescue operations that is still 
used in some areas. There are a few SAR teams around here that use 
SARTrac on both amateur and public safety frequencies (not the standard 
APRS channels) to keep track of search teams and put them up on big 
screens at the search base.
