Duration values - RsH - 01.07.2009
There are actually two values I need to see, where it now says Duration. Duration is elapsed time from the beginning of the first of the several files that may be combined via import and the ending of the last of those files. That is, in effect, the elapsed time, start to finish.
The second value, which I also need to see, is the Travel Time. When all of the 0 meter traveled positions have been removed, there remains the positions were movement occurred. In the case of my ASUS R300, the elapsed time might be 21:54:52 but the travel time, with the GPS recording one position per second, is 28557 positions, after those 0 movement positions have been removed. There are 86,400 seconds in a day, so the travel time is 07:55:57 and in this case that means that the average speed for the trip while the car was actually in motion was 81.5 km/h, since the total distance shown is 646.7 km.
That computation of average speed is also easy for the program to do IF it removes the no movement time from the total elapsed time, and again it would be a nice to have the item show 646.7 km @ 81.5 km/h average speed, which is based on the precise math I did above... Total distance divided by traveling time provides the average speed.
Is any of this reasonable to expect out of the program, and if so, when might it be available?

Hi Bob,
you know, I always try to keep the program as simple as possible. If you remove all positions which showed no movements via the "Remove duplicate positions" dialog - won't you get the travel time then?

No, since, as an example, I have just combined 4 GPX files that make up our trip from Chambersburg, PA to our home in North York, ON. That includes an overnight stay at a motel in Springville, NY so the elapsed time, even when all of the zero movement is removed still is computed by the program from the beginning of the first GPX file to the ending of the last GPX file, which are now one file, with time gaps. The way to compute the actual time spent travelling, in the case of the ASUS R300, which records once per second, then is to count the number of positions that remain after removing the duplicates and 0 movement positions and divide by 3600 to get the hours and decimal hours travelled, subtract the hours and multiply by 60 to get the minutes, and subtract the minutes and multiply by 60 to get the seconds <grin>... Not particularly hard to do, and what I actually did do... The elapsed time is from the morning of one day to the middle of the next day, the travel time is about 8 hours. The program shows the elapsed time, not the travel time, where it shows the distance travelled.
Keep the program simple... as I can easily do the math I am suggesting would be appropriate when more than one GPX file is used to combine the files and get a total trip overview, as I have done in this case. I have no idea if anyone else does the sorts of manipulation of files that I do <grin> and therefore would find this feature useful.

I've never heard from someone else doing these calculations. As long as this doesn't change I'd like to solve this with the planned CSV format which allows you to do your calculations in Excel. Is that feasible?

Yes, of course... I can do it in Excel or QuatroPro [which I prefer] or just using TapeCalc, which is my preferred calculator. I have no problem with this one being manual.
