I have tried the google service with the parameter write in the manual but it doesn't work. Do you have a solution?

Hi, same problem for me in release 7.0.2, the message is: "Error updating altitude".

In the previous release (5.x.x) it worked fine with the same parameters and, with those same parameters, it works fine on online service (i've an API Key for testing pourpose).

The parameters are: samples = "48", url = "http://maps.googleapis.com/maps/api/elevation/xml?locations=$%7Bcoord">http://maps.googleapis.com/maps/api/ele ... ns=${coord">http://maps.googleapis.com/maps/api/elevation/xml?locations=${coord}", separator = "%7C" (|), search element = "elevation".

It would be very useful to know, if possible, were to find the "request response" (it's located in Android file system ? ), ie, as described in google api elevation service developer's guide:



"An Elevation status code, which may be one of the following:



OK indicating the API request was successful.

INVALID_REQUEST indicating the API request was malformed.

OVER_QUERY_LIMIT indicating the requestor has exceeded quota.

REQUEST_DENIED indicating the API did not complete the request.

UNKNOWN_ERROR indicating an unknown error.

When the status code is other than OK, there may be an additional error_message field within the Elevation response object. This field contains more detailed information about the reasons behind the given status code."

Dear Orux,

did you see this note ?

Any suggestion about this ?

Many thanks in advance !

...

I'll check power saving settings, but it worked for almost two hours before the bug occurred, and my phone was plugged to a power cell

Hi,

"power settings" refers to single app settings too, eg. force app stand-by when put in background for memory or battery optimization sake, etc...

Check app settings, this solved for me.

I'm using oruxmaps for track recording during mountain bike tours. At the end of a tour statistics shows e.g. approximately 1000hm, but after the save of the track the statistics shows only 900hm. This loss in the statistics is reproducible, although the persentage of loss ranges between 5% and even 20%. The device (LG G5) has a build in barometer and I configured oruxmaps to use this altitude calculation. I tried to deactivate all features, which might related to an auto correction of the elevation values, but still the elevain gain ist reduced drastically on the save action.

So is this a bug? Or is it an advaced feature which I simply not yet understand?

Hi, do you tried activating "barometer autocalibration" ?

Or you might use "DEM files" as barometer autocalibration method too (obviously after downloading DEM files for your area).



best regards

When saving a track the values of elevation gain/loss are significant decreased.

But if you simply add the elevation differences between the single points from the gpx, then you get the original value.



In an extreme example the elevation gain calculated from the track point of the gpx is 1371,35m while the header of the gpx contains the value 971m, which is somehow calculated by oruxmaps.

I remember that I've seen during the tour the 1200m value for the elevation gain was displayed and there was some elevation gain after this point.



Any idea, what's going wrong?

Unless you have a barometer in your device, the altitude calculation made by GPS alone is very inaccurate.

So you should rely on DEM files for the altitude calculation: it will not be perfect, but it will be a good estimation.

Thank you very much, Orux: your suggestion solved my same problem too.

Have a nice day !
