Save some space...

[RsH]

Below you can see the first 4 positions from a file that I have out of my I-gotU GT-120, and as it was output by Route Converter 1.29.17, where Route Converter changed the speed to M/S from Km/H.

Please save me some hard drive space and cut down the speed from the 15 decimal places to a shorter number of places, as even 4 decimal places in terms of m/s comes down to a mm/s accuracy. You can also round the elevation down to 2 or 3 decimal places, since the best a GPS will do is be accurate to the nearest meter or two of elevation. In a larger file, that will save quite a few kilobytes of space per GPX file. Mobile Action's numbers are inherently suggestive of a degree of accuracy that we know is NOT there.

FWIW

Hi Bob,

to save hard drive space, set the following registry entry to true

[HKEY_CURRENT_USER\Software\JavaSoft\Prefs\slash\navigation\util]
"reduce/Decimal/Places/To/Reasonable/Precision"="true"
