[Geomoose-users] refresh layer

[Brent Fraser]

Jim,

   I was able to get it going with a few minor changes (I removed the 
authentication request and went straight to the "getdata" call; might 
want to make that part optional).  Another change I'm thinking about is 
to use a  "window.setInterval" call to get the data at a specific 
interval (say 15 minutes since my phones report at that interval).  And 
do some labeling, marker rotation, popups,  table of attributes, etc.....

Thanks again for the code!

Best Regards,
Brent Fraser
