Hi,



I'm using V.7.5.4 GP on Huawei P20Pro and I have the following issue. If I for example choose in main menu "Maps" and close it, my map display in main screen is empty. I have to tip anywhere on the screen and it is there again. It seems to me, if there is a refresh missing. This happens as well, if I select other menus, which were displayed over the hole screen. Even if I open the Info screen, the map display is vanishing. Is it a known issue?

Workaround for me is to tip anywhere on the screen and it will be displayed again.



Best regards

Uwe

Hi Maki,



thank you for your answer!



Do someone know, when the next release will be launched? The last is quite old...

Another quirk in the current version is MAPQuest. MAPQuest doesn't work anymore and it should be deleted in the next version.



Best regards

Hi,



I want to ask, when OruxMaps Donate will be updated and support mapsforge 0,5?



I want to use the new mapstyles of openandromaps.



Thanks in advance and many greetings

Uwe

...After configuring BRouter directly it works now.

And MapQuest stopped it's service:-(   So it would be nice to eliminate this from Oruxmaps...

Hello,



I suddenly have a problem. After quite a long time I want to use BRouter or MAPQuest. Both don't work anymore.

BRoute comes up with this message: "java.lang.RuntimeException: Segment/directory... does not exist"

MapQuest with this message: "End of input at character 0 of"



I am using Oruxmaps on my Note3 with Android5.0



Thank you for help in advance.

@ Holton: yes, what you are saying is my understanding as well. My Samsung Note3 has a temperature compensated barometric sensor installed. This setup is compareable to the Garmin-Setup... only the software makes the difference. A rule of thumb is, to multiply the horizontal error by three, to get the altitude error. When I used my Garmin, I always had to calibrate my baromtric Altitude and Garmin developed a algorythmic, which separates the difference caused by weather changes. That worked really good...



@ Orux: the automatic barometer calibrations works for me! Thank you! I would be happy, if you could explain, how does it work. Does it only once at track start a calibration, or is it active during the hole day?



Uwe

Hi Orux,



again thank you very much for this awesome service!!!!



I just installed the new Beta6.4beta6 and I will test it as soon as possible.

Hi Dieter!



The added value is, getting offline altitude-data.

I use them for calibrating the barometric altitude, because they are quite exact.

In my experience, setting Altitude to DEM is not working properly. It shows much too high Altitude-Gain values



Uwe

Hello,



as I said, I need a quite exact measurement of Altitude-Gain. The DEM-Altitude seems to get the height quite good, but there are a lot of little virtual steps. All this little steps are accumulated to the Altitude-Gain and this is the cause of the much to high measurement in this mode. You can see this in the statistic-graph. If I use Barometric-Altitude, the result is much better... but only if there is no significant change of weather (barometric pressure). The most exactly way to evaluate Altitude-Gain is, to recalibrate the barometric-sensor from time to time. The algorithmus has to look, if the difference between barometric- and DEM-Altitude changes. If it does, the barometric sensor has to be recalibrated and the error caused by weather-change of pressure has to be corrected in the Altitude-Gain. Of course it is a little bit complexer, as I described. There has to be a threshold defined and the values have to be averaged.

A second approach could be, to eleminate the little steps of the DEM-Values. DEM-Interpolating set to ON doesn't do the job. Maybe simple averaging can help!?

I know, that this is not a simple task... But especially for hikers and mountainbikers the Altitude-Gain is a very important value.

As I mentioned above, I switched from Garmin to Oruxmaps... and after a lot of testing and learning, I am quite satisfied with OM... only this last point brings me back to Garmin :-(

Hi Janick,



I'm using oruxmaps on a Note3, too.



But keep in mind, that always you hold your phone in your hands, the temp will rise and produce irrelevant data to the graph...



Uwe

Hi Darsosan,



it`s here the same and you do nothing wrong ;-)



@all:

And I have one more question: is there a data-field, which displays "Barometric Altitude"? Monitoring GPS-, DEM- and Barometric-data would archieve more transparence. Especially, if the "Auto-Calibration" would have been calibrated...

Hi Orux,



thank you very much for your fast answer and for your awesome software!



Ok, I look forward for the implementation of the automated barometer calibration feature. In the meantime, I will test DEM-Altitude and manual calibration...



Uwe

Hi,



I was using Garmin devices for several years. But now, I gave Oruxmaps on my Mobile Phone (Samsung Note3) a try... and I am really surprised! After some hours reading and testing, I am able to use it now. I am using it for hiking and for mountain biking and in conjunction with the OpenAndroMaps, it fits all my needs.



But I have a question about measuring altitude. With my Garmin, I calibrated the barometric Altitude before each action. And as I understood, Garmin has a built in algorithm, wich keeps the barometric calibration up to date, using the GPS altitude. Even when the weather changes, I got alwas very accurate data. Especially I am interested in elevation gain.



How does it work with Oruxmaps? I couldn't find any information, if there is a automated recalibration of the barometric sensor over time after selecting "Use barometric sensor". Or does Oruxmaps in this setting rely only of the barometric sensor?

Than I choosed to "DEM" and I got much too high elevation gain data.

Now I am fiddeling around with several settings, to find out, what works for me... Worst case is, to use barometric altitude and calibrate manually from time to time during my trip, if I see very accurate GPS readings.



I would be very happy, if someone can answer my question, if there is a built in algorithm, which keeps the barometric sensor calibrated over time or not.



Yours sincerely

Uwe
