FindMeSAR is a 'no cost' public service browser app from MappingSupport.com. It is intended for use on smartphones and tablets. It will run in the browser on a desktop or laptop computer but the location results are unpredictable.
There is also a related web page with more documentation. Many questions will be answered by the information on that page.
FindMeSAR can help emergency responders find you. "SAR" means Search And Rescue. The goal of FindMeSAR is to help make for less search and more rescue.
When you call for help with your cell phone, the person at the other end of the call needs to know your location. The FindMeSAR browser app will display:
1. Your coordinates
2. An accuracy value
3. Elevation if you are in the USA and online
4. A timestamp
FindMeSAR gets your location from your browser. All mainstream browsers offer an interface that can obtain coordinates from the phone's GPS chip. Most GPS chips in cell phones use assisted GPS (A-GPS) in order to speed up the time to first fix. The user's phone might also use data from cell towers, wi-fi hotspots, bluetooth and other location aware technologies in determining the user's coordinates.
Different emergency responders use different coordinate formats. FindMeSAR uses color-coded screens so you can provide your coordinates in the format used by first responders in your area. All coordinate formats use the WGS84 datum.
Yellow = Decimal degrees <== This format is used by 911 call centers
Red = Degrees and decimal minutes
Blue = U.S. National Grid (USNG). Same as MGRS.
Green = UTM
The accuracy value is just as important as the coordinates! If FindMeSAR has been running for at least one minute and the accuracy value is not 30 meters or less then something is wrong. Below are some things to try:
1. If you have an Android phone, open your settings and go to the screen where you turn location services on/off. Make sure the location method (or mode) is set to "GPS Only" (or Device Only).
2. If you are inside a building try to go outside or next to a window so your phone can get better data from the GPS satellites.
3. If you are in a vehicle try to put your phone next to the windshield so your phone can get better data from the GPS satellites.
4. If you hold your phone so your hand covers the GPS antenna then your phone will not get any data from the GPS satellites. Hold your phone in portrait orientation with nothing blocking the upper half of the phone.
5. Remember, if you are using a desktop or laptop computer then results are unpredictable. FindMeSAR is intended for cell phones and tablets.
If you are in the USA and your device is online then a few seconds after you tap "Stop", your elevation will be displayed.
FindMeSAR will not work if its files on your phone get corrupted. Here is how to reload the app’s files to your phone so it works again.
1. Delete the app.
2. Browse to findmesar.com.
3. Wait for the app to open.
4. Reload the app.
If the above steps do not fix the problem then open the more documentation page and tap the button "FindMeSAR Known Issues". Scroll down a bit and read the section "If FindMeSAR opens but never seems to work right...."
This link will start GISsurfer which is a web map. The map will open centered at your location and the geolocation feature will be turned on. This feature displays a small red circle with a crosshair. This symbol will always be positioned at the coordinates produced by your phone or tablet. If you move, this symbol will follow you. Even if you remain in one place it is normal for this symbol to move around on the screen a bit. Tap that symbol to see your coordinates and the accuracy value.
When the map opens it will use the same coordinate format that FindMeSAR is displaying when you ask to see the map.
If you are in the USA then you can display a high resolution topographic map. Tap the basemap button (next to the Menu button) and select "ESRI scanned topo USA". In other countries, try different basemaps to find one that best meets your needs. For example, you could turn on the basemap "ESRI aerial clarity" and then turn on the overlay "ESRI roads and labels". If you are lost, perhaps this map will help you self-rescue.
The best way to start the app is with a bookmark in your browser since you will automatically get any new version. If you have an iPhone and start FindMeSAR by tapping its icon on your homescreen, then due to a bug in iOS you do *not* automatically get any new version. Tapping "Reload" after the app opens will fix this problem by installing any new version of the app.

FindMePro is another 'no cost' public service from MappingSupport. This browser app is a research tool that anyone can use to see how different settings on their phone affect the location accuracy of the GPS coordinates produced by their phone. In particular, Android users can compare the three locations modes offered by their phones.
