Thanks MMT2020, working well on my Xiaomi Redmi Note 8 Pro. A problem that I'm having is that when I transfer a track GPX to my pc to use with Memory Map the track isn't displayed and Memory Map indicates that the track is of zero length with zero trackpoints. It is displayed correctly if I add the 'trkseg' tag before & the '/trkseg' tag after the trkpts tags. I didn't have to do this with older versions of MMTracker
[Android Apps and Games] MMT_2020:
I can see that this could occur if you change a track through the track manager (for example hiding or unhiding a track). This will be corrected in the next release.

Hello All. My phone recently uptated itself from Android 9 to 10 and now the menu button is missing from MMTracker. I am currently running version 1.10.6, before I install MMT_2020's version of MMTracker, please can anyone advise me if it possible to get the menu button back, ideally without having to install a special app. Thank you.
[Android Apps and Games] fourlans:
Here a screen shot taken from my Android 10 phone running 1.19.5. Note the 3 icons in the top right of the screen, from top to bottom Menu, GPS Lock and Search. The Settings,Load Map,'Tracks, Routes and Waypoints' (Overlay), and Tracking options are included in the Menu. There doesn't appear to be an option equivalent to the old 'Screen Lock' but I've never had a need for it anyway.

HTH

* 1.19.6 Don't allow compass settings if the device doesn't have a compass

* Always output <trkseg> element in the gpx file for a track

* Tidy up notification handling in the tracking service

I've noticed that I have to load a route on my phone before it is displayed each time I start MM Tracker but the same route is permanently displayed in MM Tracker on my tablet. Both devices have their directories in main storage. Is the phone working correctly or the tablet ?

I'm using 1.19.6 on both my Xiaomi redmi note 8 pro phone and my Huawei Mediapad M5 tablet.
[Android Apps and Games] MMT_2020:
Have you got the 'Settings', 'Directories', 'Load Routes on startup'' flag set on both devices?
[Android Apps and Games] fourlans:
To be honest, I've never noticed those settings before but it was switched off in my phone and switched on in my tablet so that explains what's happening.

Thanks for your help and again, many many thanks for resurecting this app.

EDIT:

I've checked one of my old phones with version 1.10.6 installed and routes were set to load at starup. I've been using this app for nearly 10 years and probably set it on years ago and have just forgotten about it. Hope I haven't inconvenienced you.
[Android Apps and Games] Snowman11:
Have you got "load routes at startup" option (under directories) ticked on your tablet and not on the phone?

Memory Map used to produce high quality HD maps, However stopped releasing them back in 2016 because users complained about the large files.

I'm curious were these HD files ever produced in the .QCT file format? I know MM Tracker v1.6 only supported .QCT , not the newer Memory-Map format, QC3,DRM encrypted QCT etc, yet wondered if there had been any mods made to this latest build to allow that? Would be interesting to see the comparisons between the standard 1:25k scale vs HD 1:25k scale maps, now that HD phones are a common commodity.
[Android Apps and Games] gwyndewey:
Qc3

Qc3 is an encrypted format and are not files .....

Ordinance survey are quite jealous of their copyright

It needs someone to reverse engineer the disks and convert them to .qct files for it to work no one has done that yet.

Switching map scale.

Great to find 1.19.6 after using 1.10.6 for years.

I'm using Android 9 on samsung S8 and Ordnance survey 25 & 50k maps from 2015..... I think. All are from the same source but some will switch scale ok but others don't. All will open using Map at Position.

Anyone know why this may be?
[Android Apps and Games] boomboomer:
I've noticed that if you have the GPS lock enabled, then scroll the map away from the lock, that using the scale in and out buttons results in the map position changing - but with GPS unlocked the scale buttons work normally.

I haven't noticed the scale buttons not working at all though.
[Android Apps and Games] freelander303:
Working with qct files >2gb

The new developer has been really helpful getting the app running with my Android 9.

Has anyone found a way of loading qct maps over 2gb? They do load but show white space for some sections. I wondered whether there's a way to split the file into 2 smaller qct's.
[Android Apps and Games] carlosantoniolopez:
It is possible to split qct files to overcome the 2Gb limit - I did it with an OS 50k map some years ago. Unfortunately, at the moment I can't remember how I managed it, but I will post again when I do!

We are very lucky to have MMT_2020 taking such a helpful interest in this app :)
[Android Apps and Games] carlosantoniolopez:
Ah... found the instructions for splitting qcts:

https://www.facebook.com/notes/geoc...n-of-maps-to-mobile-devices/10152117084215306

On my version of Memory Map, you have to select 'Operations > Send enclosed map to Mobile Device' when you right-click on the route.

.mmi and .qct files also get created automatically, at the same time (presumably assuming they exist for the source map).

Good luck!
[Android Apps and Games] xdarb:
I too am seeing this problem with the latest version of MMTracker. When you use the scale-in and scale-out buttons, some maps are skipped (eg. it goes straight from 1:25k to 1:250k skipping the 1:50k map), and when it loads the new map it's not centred on the same location.

Route data

Thanks for updating. Ive been using since originally released and now upgraded to my S10.

However I can't seem to see/find route data (distance) in route options (e.g. as V1.10.6)?

Previously i could select a created route and was given option to select route data (providing total distance and number of waypoints). There does not appear to be an option find total route distance in newer version.

Hi. Installed this on Android 9, but it has problems searching for directories. Is there a fix please?

hanks.

Hi.

Please ignore my previous question?. Just installed 1.19.6. Setting the map directory works, and it records the location. I can set the 3 other directories and it remembers them until I exit the app and restart it.

After setting the map directory to a directory containing a .qct and a .qed file, when I try to load a map, I get a screen with

select map to load (Google zoom level)

but the name of my map is not displayed.

What am I doing wrong?

Thanks
[Android Apps and Games] Teddy35:

I've moved my map to the SD card, and now it works...

Good work MM_2020

[Android Apps and Games] mmtuser001:
Very many thanks to MMT_2020 for all your technical skill and endeavour, much appreciated.

I'm using MMT v1.20.0 but having a problem when transferring a .gpx track to my pc to use with Turtle Sport and Sporttracks v2. Both report an error when importing. However, if I edit the .gpx file in Notepad by finding all +0000 and replacing with Z it then imports correctly into both programs. I didn’t have this with MMT v1.10.6

Example: before & after edit

<trkseg>

<trkpt lat=……………<time>2020-12-14T14:26:50+0000</time></trkpt>

<trkpt lat=……………<time>2020-12-14T14:26:51+0000</time></trkpt>

Find & Replace in Notepad. Find all +0000 and Replace all with Z

<trkseg>

<trkpt lat=……………<time>2020-12-14T14:26:50Z</time></trkpt>

[Android Apps and Games] Sideburnt:
Hi, so I've got a range of historical points of interest saved as a gpx file. I'm pretty sure it used to be possible to view all of them overlaid on a map so I could see what there was in the area I was in.

It looks like that has switched on the new version to open them individually via the waypoints menu. Is this right?, is there no way to have all of them show?
[Android Apps and Games] MMT_2020:
I assume that you have set the 'Load Waypoints on startup' flag (Settings, Directories)?

If you have and it still isn't working, then please send me the file and I will investigate further.
[Android Apps and Games] Sideburnt:
Hi, that would be great. I've got load waypoints checked and the directory added correctly.

[Android Apps and Games] thepointyman:
I have been using MM Tracker sine 2013 and been very impressed by the App. I am so glad tha you guy at XDA-Forums rescued it. I am now running 1.22 on a Moto G& Plus. However, I have noticed a probelem with the spped caclulations. The displayed speed doen not correspond to a simple calculation of distance divided by time. See the attached screenshot. The displayed speed: mean velocity 1.0mph; mean moving 1.5mph. recorded distance 2.29 miles moving duration 38.6 minutes gives 3.6 mph, definiteky over optimistic. Using the toal duration gives 2.29mph, more realistic.

I realise that the speed caclulation is made by averaging the speed betwen each waypoint rather than dividing the distance by time but the displayed result is misleading. The distance is correct and coroborated against ViewRanger & OS maps. The speed calcuation is correct is used in a car. I therefore assume that the problem is making accurate readings when the disatance walked between taking waypoint is too short.
[Android Apps and Games] MMT_2020:
I've just had a cursory glance at the code, and it looks like the speed calculations are derived from the speed element sent by the gps chip.

In the gpx file for the track are there speed entries for each of the trkpt elements?

And do they look sensible!
[Android Apps and Games] j.i.wilson:
I believe the speed (velocity?) is computed by comparing one position with the next. "Position" provided by GNSS is 4 dimensional and so includes a time coordinate. The time is precise being provided by atomic clocks. The position contains errors of the order of metres. However these errors are highly correlated to time and when they are differences they largely cancel out. BUT, when dealing with small velocity the residual error is large compared to the distance travelled between fixes ( usually 1 Hz). Hence the relative error in velocity is comparatively large when dealing with small velocities. The magnitude of the error stays roughly the same when travelling at higher velocity and hence the relative error is much smaller. As an aside I would predict the effect on the bearing (the second component of velocity) would be equally marked.
[Android Apps and Games] MMT_2020:

*Make waypoints semi transparent and not too small

*Correctly deal with orientation change whilst navigating or adding a route

*Encourage users to set up separate directories for Maps, Routes, Tracks and Waypoints

*New setting "Calculate track velocity" in gps settings. If set to true, then for 'Track Data' the velocity will be calculated from the individual trackpoints rather than using the GPS supplied speed data

*Show OS grid refs in Position Info box as 10 digits rather than 6

*Other bug fixes and performance enhancements

[Android Apps and Games] netwave:
Thanks for another great build MMT_2020 I'm loving it! (y)

Request: Can you set an edit to show the tracking button by default in the next release please?

No biggie if not, ile just select it in the user interface each time.

What I am interested in of late is Elevations,

In my Map folder I have sub folders, named marine charts, O.S Explorer 1.25k & O.S Landranger 1.50k to name a few.

I noticed there's now an elevations folder there, yet it's contents are empty!

I'm thinking it's empty because I map categorize, yet some users just dump all there maps in one place without categorizing hence the elevations folder is there & will start filling with data.

The bulk of my map reading is via O.S explorer 1.25k & in that folder there is another Elevations folder, This ones got a .zip inside with .hgt, .mum, .swb which must be the downloaded elevations, great!

Is it alright to transfer the downloaded elevations from one device to another & expect it to work?

And....

Is there anywhere I can download a massive elevations file of the UK which will work in MMT?

Rather than consume data from my network provider!

In settings/elevation tab MMT has the option to download Elevation data via WiFI

How does this feature work?

There are next to no WIFI hot spots in the Countryside while tracking, Though didnt know if it's something that can be downloaded via WIFI at a later date after tracking has finished?

If not, finding country elevation files would be useful.
[Android Apps and Games] MMT_2020:
Any changes you make to settings will be maintained across updates of the software, so you shouldn't need to reapply unless you un-install and re-install.

The elevation files come from NASA Earthdata and each zip file covers a 1° square of the world and gives us 30m granularity, so the City of London for example is contained in the file N51W001.SRTMGL1.hgt.zip as its lat/lng is 51.5019/-0.09828.

I hold all of my maps in a similar sounding structure to yourself and just point the MmTracker maps directory at the top of this structure. MmTracker is very good at searching out all of your maps in the structure and then keeps an internal database for its use in finding a suitable map.

Elevations are currently used by the Position Info popup as well as for the altitude graphs that you can draw for a route.

If the relevant elevation file is not available, then it will be downloaded from NASA immediately if you are Wifi connected and will only use phone data if the 'Only download over Wifi' box is unselected in the elevation settings.

None of this elevation stuff will happen at all if the 'Use Elevation Data' box is unselected!

Does that make sense?
[Android Apps and Games] netwave:
Understood thanks for clarifying
[Android Apps and Games] fourlans:
MMT_2020,

I recently completed a walk and a screenshot of the Track data as recorded is attached. The distance & elapsed time are correct but the mean velocity , the mean moving velocity, the maximum velocity and the duration moving don't seem to be quite right. I'm under the impression that mean velocity is the distance divided by the elapsed time and the mean velocity moving is the distance divided by the duration moving. How does MM Tracker calculate these numbers? Also Memory Map on my pc shows a maximum velocity of 15 mph which occurred (I think) near a building and my gps signal may have interrupted. Does MM Tracker ignore any points on the track such as this when calculating the track data and how does it identify them?

Thanks once again for a superb app.
[Android Apps and Games] MMT_2020:
Lots of things to consider here I'm afraid.

'Settings', 'GPS and Tracking', 'Track load min distance' allows you to define the granularity of points read in from a gpx track file.

'Calculate track velocity' allows you to define whether the speed value from the GPS receiver is used (if this is available), or whether this is calculated as the distance between 2 adjacent trackpoints divided by the time taken between the 2 points.

MmTracker calculates the Moving Time of the track, as the total of all the times where the velocity between 2 trackpoints is greater than 0.1 metres per second.

Up to MmTracker version 1.22.3, then the Mean Velocity is calculated as the mean of all of the individual velocities as calculated above, and the Mean Velocity Moving as being the mean of all of the velocities which are greater than 0.1 metres per second.

As of version 1.22.4, I have changed this calculation so that the Mean Velocity is simply the overall distance divided by the overall time taken, and the Mean Velocity Moving being the same for the Moving Time.

Does any of that make any sense at all!!!!

fourlans, I will PM you with a copy of 1.22.4 for you to have a play with to see if that works better for you.
[Android Apps and Games] fourlans:
It all makes perfect sense. I hadn't noticed the changes made in 1.22.3 regarding the GPS supplied speed values and the switch to use them or not during tracking.

I've just tried 1.22.4 and can see what you've done so that the Track Data numbers make more sense. Many many thanks for your efforts.
[Android Apps and Games] MMT_2020:
MMTracker 1.22.4

*If navigating, show the bearing to the destination

*In the Position Info Box, if less than 5km away, show effort required (+/- metres/feet) to get from current position
