[meteorite-list] "Death by GPS" in desert

[GeoZay at aol.com]

>>This sort of thing happens in this  country during winter. Some areas of 
Canada are poorly mapped and very  often
the GPS data in the unit is already outdated. For instance many stores  
here in Victoria (BC) have closed, moved etc,
new roads have been  open for a couple of years and yet the updated GPS 
mapping data uploaded  from the provider
still isn't "updated".<<


My wife  and I use the SPOT system that seems to work great everywhere we 
used it. She is  a serious backpacker and I keep tabs where she's at when she 
sends a well being  signal wherever she's at. The only places she seems to 
have trouble getting a  signal out is if she's in a deep canyon. I've tested 
a few times its accuracy to  within about 20 feet of where she's at. Its 
reassuring to get her signals on my  computer that also sends one of three 
pre-made messages...such as: "Hi I'm doing  fine and am having fun.". Or 'I'm 
in a serious situation and need to be  rescued."
