This is the easiest way to share your UTM coordinates! - Directly read the UTM coordinates of your position. Rotate the phone for larger numbers. - Send your position as UTM coordinates via e-mail or iMessage - A map link is included with the message - The receiver can use the map link on any smartphone or computer (Google Maps™ will open in the browser) Note that some competitor products are creating a map link which will translate to a nearby street address. This is NOT done by this map. Instead, IT WILL ALWAYS SEND A MAP LINK SHOWING A POSITION WITH BEST POSSIBLE ACCURACY. Even though sending a link that translates to a street address might sometimes be convenient in cities, it can also lead to huge errors. Imagine, for instance, that you have decided a meeting place somewhere in a large park. Then it is not so smart if the app instead indicates a position on one of the streets that are surrounding the park. SO IF YOU WANT THE MAP LINK TO SHOW THE CORRECT POSITION, CHOOSE THIS APP. UTM zones can either be handled fully automatically or entered manually as a one-time setting. (The latter may be a requirement in areas where maps are produced with non-standard UTM zones in order to avoid zone boundaries crossing a country or a map sheet.) The supported datum is WGS84. Please, check that it is consistent with maps used in your region. Some other datums are very similar to WGS84 and are compatible within a few meters accuracy, e.g. NAD83 in the US and ETRS89 in Europe. Note, however, that some older datums, which may still appear on some maps, are NOT compatible, e.g. NAD27 in the US and ED50 in Europe. (This app is not possible to use in the polar regions, since "UPS" is not supported.) --- Disclaimer: All software may suffer from bugs and all electronic devices may malfunction or run out of battery.
