1/9 Here is a tip that can save a life (yours?) in an emergency. When you call 911 they might not know where you are unless you tell them. I developed #FindMeSAR as a public service project to help solve this problem. #SearchAndRescue #EmergencyManagement

2/9 #FindMeSAR (findmesar.com) is a webpage that uses the GPS in your phone to display your coordinates and accuracy value. Several coordinate formats are supported and each one has a different colored screen.

3/9 The yellow screen displays your location in latitude longitude, decimal degrees. This format is used by all 911 call centers.

4/9 Blue screen displays U.S. National Grid (#USNG) which FEMA has identified for use in ground operations. This is the same as Military Grid Reference System (#MGRS).

5/9 FindMeSAR works offline - but there is a trick to it. Open it the first time when your phone is online and the code for this webpage is saved in a special part of the browser's memory. (Service worker + AppCache)

6/9 If you need to be rescued and can only send out a text, you can still use FindMeSAR to include your coordinates (use yellow screen) and accuracy value in your text. This assumes you previously opened it when online.

7/9 This is also useful if you want to tell friends to meet you at a spot with no street address. There is a group of off road enthusiasts that post a FindMeSAR screenshot when they get stuck and need volunteers to come help.

8/9 There is an icon you can save on your homescreen and a “Tips” button with more information.

9/9 If you ever need to call 911, FindMeSAR can be a backup way to give them your location. Remember to use the yellow screen and also give 911 the accuracy value.
