Quickly and easily determine a remote GPS location from two, or more, geolocated points with compass bearings to that location.
Specifically designed for use in the field, Field Triangulate supports:
- Fully automated use of iOS device location. Compass bearings are best manually entered.
- Manual entry/edit of any/all readings.
- On map display in various display modes.
- Manually update device bearings (e.g. for use with a compass.)
- Share the triangulation to others.
- Multiple latitude/longitude formats:
-- Decimal degrees
-- Degrees and decimal minutes
-- Degrees, minutes and seconds.
-- (Display for UTM.)
Basic usage:
Use your iOS device & compass to take bearing on a remote location from two locations and Field Triangulate will calculate and display the GPS coordinate for the remote location.
Advanced usage:
Enter readings provided from a remote person (perhaps by iPhone or radio) and add your own readings manually in order to calculate a remote location.
I would like an app that does what this one is supposed to do. This one doesn’t do what it is supposed to do. This app is wildly inaccurate. I have been testing in Utah desert with large distinct landforms, similar to monument valley, that should be easy to point at and take a bearing. The accuracy is so far off the app is useless. Also, the layout and procedure is unintuitive and the documentation is poor. When you do figure out how it is supposed to work you also figure out how poorly the layout supports the function. Finally, the developer does not respond to email questions regarding functionality. This app would be a disappointment if it was free. It is a bad joke at $7.99. I think a refund should be provided but the App Store says this app is not eligible for a refund.
Not intuitive
Not easy to use intuitively. I tried to confirm the location of a peak using my location and couldn't see how to do it.
Practice first
Downloaded it last minute to use for fox hunting with my radio club as my son backed out last minute.
I like it and have since practiced it and do like it as a one person operation. Can save points and historic readings. I recommended it to my radio club.
Useful but problematic
I’ve been seeing a consistent problem where projection lines disappear at carrying zoom levels, most often when close up.
Another issue is when holding the phone sideways to sight down the edge of the phone the keyboard blocks the save button on screen. Additionally, being able to use the volume buttons would work well for locking the direction in.
After setting a projection line the map at times will zoom out to a world view requiring panning and resetting the zoom level.
Finally I’d like to be able to exit from creating a projection like without creating the line on the map. As it is now, tapping off to the side will return to the map but will still set a projection line at 0 degrees. One must then go to the listing of readings and delete it from there.
Good for radio fox hunting
Attaching iPhone to rotating radio signal locator, this app helps to quickly triangulate on map where the “fox” is hidden. Note to developer the compass hdg should be more visible when setting up the fix. Maybe even using the camera as a target sight.
Very limited usefulness
I thought I'd found an App that could be used in the field to spot-in multiple locations with heading to a feature to triangulate it's location....this is NOT it. Manual entry of coordinates. No map function.
