GPS formatting for Tom Tom


Hi All,

What should my Tom Tom be formatted too ?

Degrees  d.d*

Minutes d* m. m

Seconds d* m  s

Please excuse the asterisk as I couldn't find the degree symbol.

Thanks smile

whichever you prefer. If you use a publication like camps australia wide, might be easier using the same format as they do though. Same if you use google maps I guess too. Use whichever is more user friendly for you.

Camps Australia wide use degrees, minutes and decimals of minutes.   E.g. S 38 degrees, 159.421 minutes. They don't use seconds.

The question has been answered but, for future reference to the OP and anyone interested, the Degree symbol (25 °) can be found by going to your Character Map (assuming you are using a PC with Windows) Start - Accessories - System Tools - Character Map.

The symbol, along with many others,  is around the middle of first page.  Just Click on it, Select then paste it where you want it.

Someone may be able to tell how to get it on other systems.

Cheers Neil

Or hold down the alt key and type 0176 on the numeric pad, then let the alt key back up... 500°

If your TomTom can be used with Degrees, Minutes and Seconds, use it that way. This will give a more accurate position. I recall in one town I passed thru, I had my TomTom set with Degrees and Minutes only. I punched in the co-ordinates for a free camp and ended up on the wrong side of the river. My TomTom showed I was at the site, but I could see it across the river, a distance of about 200 meters. Had I used seconds, the problem probably would not have arisen. For general use such as the City enter of a Town, Degrees and Minutes would be ok.

Apology to OP.
Just had a look at my Camps 6 and GPS coordinates are in Degrees, Minutes and Seconds.
Cheers, Ozjohn.

The format I use because I am used to it and is the one used by almost all emergency services is degrees and decimal minutes.

NSW helicopter rescue services will only accept GPS data in this format.

 Just looking through some forums, it looks like the TomTom can accept decimal minutes up to 5 decimal places, so it should be more accurate than seconds as .00001 minute is equivalent to .03 of a second and is approximately about 1.1M at he equator. Obviously the accuracy of the GPS and how many sattelites at which positions will dictate the overall accuracy of the location. I don't have a TomTom to check this out myself though, so will stand corrected if someone else has more info.

I beleive you will have to set it to the format that you are working from, as you cant enter a co-ord; to a different format. Maybe there is a conversion chart some where.

That is correct JC, you need to enter the coordinates in the same format as shown in the information you are using to locate the POI. For example if the listed POI shows D, M, s then you enter the figures in the same format as they are listed unless you can convert them to another format. However, most GPS's can accept coordinates in different formats.

Maybe this will help some one, I could not copy the complete spread sheat/program.

Forgot that I had this. have never tried to use it as it simplier to change the format on GPS to match the info that you are working from.

Just had a look & it can be emailed as an attch. 13.5kb.

                                        Example for manual conversion to decimal degrees

                   
Convert to decimal degrees                                       
                    Degrees    Minutes    Seconds           
Degrees    Minutes    Seconds            33    58    39           
33    58    39                               
                    Multiply minutes by 60        58 x 60=    3480       
becomes                     To this, add seconds        +39=    3519       
                    Divide this by 3600        3519÷3600    0.9775       
33.9775    degrees                Add degrees        +33    33.9775

Decimal Address        34.83916667            Decimal Address        34.8392     degrees       
                                       
becomes                     Degrees             34       
                    Subract degrees integer        34.8392 - 34    0.8392       
Degrees    Minutes    Seconds            Multiply by 60        0.8391 x 60    50.352       
34    50    21            Thus minutes             50       
                    Subtract minutes integer        50.352 - 50    0.352
