Confusing GPS Formats
I have several GPS receivers that provide coordinates like these:
- 4107.9095 17502.6079 : embedded module
- 4107.8780 17502.6300 : gps stats phone app
- 4107.8861 17502.6290 : Navman usb mouse gps
Google Maps doesn’t like this format, so you have to change it slightly. It’s a GPS format but missing the punctuation. “4107.8861 17502.6290” becomes “S 41 07.8861 E 175 02.6290”.
Finding the same location on a map and reading off the coordinates:
- -41.131357+175.043879 : iTouchmap
- -41.131367+175.043873 : NZ Topo Map
Be careful not to change the syntax inadvertently converting it from GPS format to Decimal Degrees. It’s a different location but just far enough away to be very confusing. “4107.8861 17502.6290” is not “41.078861 175.026290”. Obvious when you think about it.
Read from the Simple-OSD, “4109.2211 S 17504.4029 E” must be entered into Google Maps as “S 41 09.2211 E 175 04.4029” to return the correct location.
Read from the DIY-OSD “4109.0005 S 17502.3347 E” must be entered as “S 41 09.0005 E 175 02.3347“.

This puts a green arrow at the point on the map. Click on the green arrow and you see 2 sets of coordinates.
click on the green arrow.
You can enter data in these formats into Google Maps:
- -41.079095 175.026079 : Decimal Degrees (WGS84)
- S41 04 44E 175 01 33 : Degrees, Minutes & Seconds
- S 41 04.746E 175 01.565 : GPS
But not:
- 60S 334184 5450585 : UTM
UTM is a decimal grid format. Apparently Topo maps have this grid on them.
