True and magnetic north have no effect on GPS accuracy. It is only relevant if you are navigating with it.
Getting into datums is really beyond the scope of this group and is a little complex. The differences in the datums that GPS units use will be far smaller than the overall error in the GPS itself (ie the 10-20m I mentioned in a previous post) Gavin...

Double tapping on the center of the compass seemed to switch from Magnetic to True. Tapping the geo co-ords also gave me the street address, and tapping the arrow in the bottom left switched me to map view and gave me the street map of the area On 15 September 2013 12:15, Douglas Tighe <littlehand...@gmail.com> wrote: Hi All, My iPhone has a built in compass which works anywhere even where there is no phone signal. On the bottom of the display its shows Latitude and Longitude. It's important to make sure you record the lat and long as well as the Geodetic Datum, as different parts on the Earth require their individual Datums because the Earth is not perfectly round. I live in Australia, we started using WGS then ADG and now the most up to date is GDA. I don't know the iPhone method of storing the Datum also I don't know whether to use the Compass on True North or Magnetic North and as well the reading can be Latitude degrees, Minutes, Seconds or Lat/Long decimal degrees. I, hoping some of the group can add to this.

I often have a camera with me that I sometimes use for that purpose but don’t find it very accurate related to GPS activities. I’m no expert iPad user but I see nothing in it that would indicate Lat and Long for photos taken with it. I’ll call the Apple store. Thanks.

I want to climb into remote hills and read my exact location by coordinates. I stumbled onto a small cemetery with a few stone in the mountains this summer with no trails or roadbeds nearby. I did later contact the county and described the location as well as I could. They eventually found it and said they did not know it existed. Secondly, which of the group of coordinates formats does the group believe is the most useful or is it a matter of taste? Thanks.
