Hi Xavier, this is really weird. All online maps have same issue? May you give me some specific location like coordinates x, y, map OSM classic and zoom z? I have to check it because I have no similar troubles.

request done

[declivity = delta_elevation / delta_distance;]

Hi to all,
 I received today email from Martin with question about track stats. So I want to discuss about it a little.

Main question is - are elevation values correct?

Martin wrote that all stats are cca twice as big as should be. To be true, I do not tested well this feature so everything is possible here. Anyway how I get stats about elevation etc ...

- for every added point I compute elevation gain (of course not for first point in track segment)
so when new point is added, I compute distance from previous point and elevation change. From those values I compute declivity as

declivity = delta_elevation / delta_distance;

and then I sum all values by this simple method. Whole code for my elevation handling is below. Distance and elevation values are in metres and these are delta values, so difference between actual and previous point

Code Select Expand

   protected void addElevation(double distance, double elevation) {
    double declivity = elevation / distance;
    if (declivity > 0.025) {
    elePositiveDistance += distance;
    elePositiveHeight += elevation;
    } else if (declivity < -0.025) {
    eleNegativeDistance += distance;
    eleNegativeHeight += elevation;
    } else {
    eleNeutralDistance += distance;
    eleNeutralHeight += elevation;
    }
   
    eleTotalAbsDistance += distance;
    eleTotalAbsHeight += Math.abs(elevation);
    }

So this mean that is declevity is bigger then 2.5%, I take it as "uphill" movement, opposite as "downhill" movement.

What you think? Are values as you expected? Also second question. Is there any value that you miss in track stats and this value is easy to compute?

Also Martin, may you attach some more description about this "issue" (if there is any). Thanks

these are same as market. So valid ... forever

How this is possible? You turn on GPS, then exit Locus with dialog "Do you want to exit" and when you start Locus again then GPS is not turn on automaticaly? What ROM do you use?

svartbjorn and tusor, it's not a big problem to do this I think, but problem is as I said before, that rotation is needed also for compass screen and I'll use it later on some more also. So one central switch is by me better. Switch on gps screen was by me fine, but it wasn't clear enough for many people. So when there will be any other description on button, I should put it back into gps screen. What you think? Also your "north up" means like no rotation? Do not forget that when you rotate by hand, symbol also change to green backgrounded arrow to notice that map is rotated by hand

Hi Richard,
  nono, behavior of app is correct on your phone. it just start google navigation and if is not available, it should start google maps. Compute directions in Locus is also available but little bit complicated. Start draw track manually (from menu -> tools) and after you draw two points, press middle "directions" button, which allow you compute what you need. But do not expect navigation like you know from navigation software like TomTom

OK I updated text in first post. Also working example with three layer osm maps is there. About GUI for this. I was thinking about it but result was that this is not necessary. Only at least little bit experienced user can add some new map. And for him, by me, doesn't matter if he edit this in app or in some external file

but it's written twice in description on market. On info in main text and one in update text!

guys this is good idea I have to say but it have one problem. It's that rotation by compass or bearing is also used on Compass screen, and maybe will be a later too somewhere else. So rotate by this or that is a global variable for whole locus. Alternative is also to keep current settings in settings (maybe not) and also give back old button on GPS screen but with some better description. What you think?

ah sorry. you're correct. In my description are missing such a main information! I'll fix this ...

nice, keeping older free version is very recommended solution

hmm may you try to add to exported description tag something like this?

<desc><![CDATA[<html><head></head><body> ... original description <fon ... > ..... /font> and now end of html code </body></html>]]></desc>

what this will do in your software. Thanks

můžeš mi ten soubor poslat na mail? při stažení z poi.cz mi to dělá nějakou neplechu

tohle by mělo fungovat a jestli nefunguje tak je tam chyba a tu hned opravím. díky

Thanks Blackdawn. That's exactly what I need to people do.
