How to get an overview of multiple gpx on OSM map?

_ dikkeknodel

Hi all,

 

Ever since I moved to Switzerland over a year ago I’ve been both hiking in the mountains and updating OSM details a lot. Since I hike at least 20 km every weekend, it must have totaled to about 1200 km by now all across the country. I would love to get an overview of where I have been so far.

 

Since I’ve got a GPX file of almost every hike, the data is there. I am now looking for a nice graphical way to plot all of these files at once on a nice OSM map, OpenTopoMap as a base layer would be great.

I’ve been searching for a while how to arrange this (without much programming knowledge), but I am kind of lost at the moment.

 

Does anybody have a hint?

 

Cheers,

dikkeknodel

Drag and drop your gpx in Qgis?

Hi _dikkeknodel,

I have a question - how do you record a GPX trace during 20 km walk? It should be about 4 hours.

I also record GPS traces but usually for 15-20 minutes. I use a phone with the OSMTracker app for Android with mixed results. Sometimes it records a path well, sometimes it turns the second part of the walk into a long direct line. Such a trace I usually discard.

Besides it empties the phone battery rather quickly. I usually take a power-bank with me, but still it is not a good solution to get a phone battery empty in mountains.

I am thinking of getting a dedicated device which can record the GPX files, on the OSM map, and also measure and altitude more or less correctly. The question is - what device, what model.

Best regards,
Oleksiy

If you just want to browse where you've been, JOSM
(https://josm.openstreetmap.de/) can easily handle hundreds of GPX
tracks at once, and has a variety of backgrounds you can use.  Most of
them are aerial photographs, but it also has some rendered maps.  The
topographic options for Switzerland include OpenTopoMap, OpenCycleMap,
Thunderforest Landscape, and Stamen Terrain (a pure hillshading layer,
no topo lines or anything else).

I would open JOSM and open GPX file(s). JOSM is primarily an editor, but I use it also
for visualisation of GPX files.


QGIS is another tool - typically used for processing of data, but showing GPX tracks is also
a thing that it can do.

Why not use umap? https://umap.openstreetmap.fr/en/
It has an import feature.

Hi all,

 

Thanks for all the great advice. I’ve looked into uMap and it does the job perfectly. With all the gpx of over a year of hiking imported it still runs smoothly.

I would like to prevent running into performance issues later though. Does anybody know if it is wise to add ‘simplified’ versions of the gpx to uMap instead of the original recordings with 1 s resolution?

 

Since the published data is public, I just have to take into account not to import gpx which start from my home since I value my ‘sort of anonymity’.

 

@Oleksiy

To answer Oleksiy’s question, I record with OSMand on a Moto G4 smartphone, that works like a charm. Off course there is fluctuation due to accuracy errors, I guess 10-15 m is achievable most of the time, but close to near vertical mountains it becomes much worse.

 

It however does never happen that I miss long stretches of data (except for tunnels 😝). I did have that problem in the past, when <15% battery charge and Android automatically started the battery saving mode. That just turned of the gps antenna whenever the screen was off. So now I have set battery saving mode to off.

 

Also OSMand does not drain the battery much. Usually I do take a lot of notes which OSMand attaches to the gpx and loads perfectly into JOSM. Recently I also used the voice recorder of OSMand, which really speeds up the note taking while on the go in comparison to typing. These also load into JOSM via the gpx, but some fiddling with the location of the audio is required. Taking notes on the phone does have an effect on the battery life off course. A 20 km hike in the mountains easily takes 6-8h, which my phone reaches most of the time on one charge in flight mode. I do have a power-bank as back-up, and for multi-day hikes though.

 

Altitude measurements have always been a bit tricky with OSMand. I guess the raw elevation data from gps fluctuates quite a lot, and the data processing did not do a good job filtering errors from actual elevation change. After a hike with 1000m elevation gain according to the map, OSMand often showed I did 5000m... The graph of the track you can generate in OSMand also showed a lot of spikes with instant ascents of >200m. Recently that seems to have changed and the measurements seem to better represent the actual situation.

 

Hope this helps you with you work OSM workflow!

 

Cheers,

dikkeknodel

Garmin GPSMap 6x seems to be good. I'm still using GPSMap 60, but the newest
in line is 66.

I still don't think the altitude measurement is reliable, though. Maybe if
I've calibrated
altimeter properly...

If you just want to see where you have been, desktop applications like QMapshack
and Viking are the best choice. QMapShack also allows you to store and organize
the GPX tracks in a database and has integrated routing services for trip
planning. It allows to chose about any OSM-based map as background as well as
many other online map and aerial image services.

Thank you, dikkeknodel.

I also received an email message with an advice to acquire Garmin eTrex.  I've ordered the Garmin eTrex 35 Touch with the pre-installed «TopoActive» Karte Europa, which is based on the OSM data, as I understood:
https://www.brack.ch/garmin-hand-gps-etrex-touch-370929

It supports the EGNOS, European Geostationary Navigation Overlay Service, which is supposed to correct the GPS signal. I have no idea how it works in reality. It also has got the GPS and barometric altimeters.

Best regards,
Oleksiy

Garmin GPS and OSM-based maps (was: Re: How to get an overview of multiple gpx on OSM map?)

Andy Townsend

Whilst it's great that Garmin are offering the convenience pre-installed OSM-based maps, it's worth bearing in mind that there are lots of free download options - see https://wiki.openstreetmap.org/wiki/Mkgmap for creating your own and https://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download for ready-made downloadable options.

http://garmin.openstreetmap.nl/ is a good place to start for "I want maps for a certain part of the world".

There are lots of help questions about the mechanics of installing maps on Windows, Linux, MacOS etc. at https://help.openstreetmap.org/ , and these might be an easier place to start reading than the wiki (which can be a bit confused at times).

I do have a GPSMap64s with preinstalled Garmin maps* that aren't OSM-based.  One problem with those is that they contain lots of old, inaccurate non-OSM POIs that it's impossible to turn off without removing the SD card - hopefully your OSM-based maps from Garmin won't share this problem.

Re EGNOS on an Etrex 35, assuming it's similar to an Etrex 30x, it's noticeably more accurate (within a few meters as opposed to a few tens of meters) when you're somewhere with WAAS/EGNOS coverage compared to when you're not (in my case it was Europe with and Australia without, but that was a while ago - don't know if the Australian situation has changed).

Barometric altimeter (on both Etrex30x and GPSMap64s) tend to be accurate to within 10m at the top of the hill if you've calibrated them at the bottom, but not if you haven't (apologies for being Captain Obvious there!).

Battery use on both Etrex30x and GPSMap64s are something like "one pair of rechargeable AA batteries every day and a half" (if it's on all day).

Re the new 66s my understanding is that it can use 2 of GPS/Glonass/Galileo at the same time.  Personally I'd wait to see a "review involving OSM-based map use" before getting one, but I'm sure they'll appear fairly soon.

Other non-Garmin options for "something to last all day" might be an old phone with GPS in it and user-removable batteries.  An old Blackberry might be an option (they still work after you manage to drop them on the floor, and you might find the keyboard more usable than a touchscreen when it's cold).

Best Regards,

Andy

* at the time this was essentially "free" due to availability and what stock the various discounters carried - in theory its about £60 extra, and probably isn't worth that.

Hi
There are lots of sites giving advice on GPS usage, but one I tip I found useful was always keep a charged battery in your unit. Even though it's switched off it still receives the occasional signal from satellites to keep track of their locations. if it loses coordination with them it can take ages to relocate.

Cheers

To answer Oleksiy’s question, I record with OSMand on a Moto G4 smartphone, that works like a charm. Off course there is fluctuation due to accuracy errors, I guess 10-15 m is achievable most of the time, but close to near vertical mountains it becomes much worse.

 

It however does never happen that I miss long stretches of data (except for tunnels 😝). I did have that problem in the past, when <15% battery charge and Android automatically started the battery saving mode. That just turned of the gps antenna whenever the screen was off. So now I have set battery saving mode to off.

 

Also OSMand does not drain the battery much. Usually I do take a lot of notes which OSMand attaches to the gpx and loads perfectly into JOSM. Recently I also used the voice recorder of OSMand, which really speeds up the note taking while on the go in comparison to typing. These also load into JOSM via the gpx, but some fiddling with the location of the audio is required. Taking notes on the phone does have an effect on the battery life off course. A 20 km hike in the mountains easily takes 6-8h, which my phone reaches most of the time on one charge in flight mode. I do have a power-bank as back-up, and for multi-day hikes though.

 

Altitude measurements have always been a bit tricky with OSMand. I guess the raw elevation data from gps fluctuates quite a lot, and the data processing did not do a good job filtering errors from actual elevation change. After a hike with 1000m elevation gain according to the map, OSMand often showed I did 5000m... The graph of the track you can generate in OSMand also showed a lot of spikes with instant ascents of >200m. Recently that seems to have changed and the measurements seem to better represent the actual situation.

 

Hope this helps you with you work OSM workflow!

 

Cheers,

dikkeknodel

Onderwerp: Re: [OSM-talk] How to get an overview of multiple gpx on OSM map?

 

Hi _dikkeknodel,

I have a question - how do you record a GPX trace during 20 km walk? It should be about 4 hours.

I also record GPS traces but usually for 15-20 minutes. I use a phone with the OSMTracker app for Android with mixed results. Sometimes it records a path well, sometimes it turns the second part of the walk into a long direct line. Such a trace I usually discard.

Besides it empties the phone battery rather quickly. I usually take a power-bank with me, but still it is not a good solution to get a phone battery empty in mountains.

I am thinking of getting a dedicated device which can record the GPX files, on the OSM map, and also measure and altitude more or less correctly. The question is - what device, what model.

Best regards,
Oleksiy

Hi all,

 

Ever since I moved to Switzerland over a year ago I’ve been both hiking in the mountains and updating OSM details a lot. Since I hike at least 20 km every weekend, it must have totaled to about 1200 km by now all across the country. I would love to get an overview of where I have been so far.

 

Since I’ve got a GPX file of almost every hike, the data is there. I am now looking for a nice graphical way to plot all of these files at once on a nice OSM map, OpenTopoMap as a base layer would be great.

I’ve been searching for a while how to arrange this (without much programming knowledge), but I am kind of lost at the moment.

 

Does anybody have a hint?

 

Cheers,

dikkeknodel

Re: Garmin GPS and OSM-based maps

In reply to this post by Andy Townsend
Hi Andy,

Thank you. It was helpful.

It is definitely better than a smartphone, mostly to the battery (14-16 hours) & EGNOS correction. I learned how to install the OSM map on the device, - basically export/copy/paste the .img file.

I also acquired an accessory, - a big aluminum clip to attach the device to a backpack. It is quite convenient to keep it outside, well visible to satellites.

Best regards,
O.

Whilst it's great that Garmin are offering the convenience pre-installed OSM-based maps, it's worth bearing in mind that there are lots of free download options - see https://wiki.openstreetmap.org/wiki/Mkgmap for creating your own and https://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download for ready-made downloadable options.

http://garmin.openstreetmap.nl/ is a good place to start for "I want maps for a certain part of the world".

There are lots of help questions about the mechanics of installing maps on Windows, Linux, MacOS etc. at https://help.openstreetmap.org/ , and these might be an easier place to start reading than the wiki (which can be a bit confused at times).

I do have a GPSMap64s with preinstalled Garmin maps* that aren't OSM-based.  One problem with those is that they contain lots of old, inaccurate non-OSM POIs that it's impossible to turn off without removing the SD card - hopefully your OSM-based maps from Garmin won't share this problem.

Re EGNOS on an Etrex 35, assuming it's similar to an Etrex 30x, it's noticeably more accurate (within a few meters as opposed to a few tens of meters) when you're somewhere with WAAS/EGNOS coverage compared to when you're not (in my case it was Europe with and Australia without, but that was a while ago - don't know if the Australian situation has changed).

Barometric altimeter (on both Etrex30x and GPSMap64s) tend to be accurate to within 10m at the top of the hill if you've calibrated them at the bottom, but not if you haven't (apologies for being Captain Obvious there!).

Battery use on both Etrex30x and GPSMap64s are something like "one pair of rechargeable AA batteries every day and a half" (if it's on all day).

Re the new 66s my understanding is that it can use 2 of GPS/Glonass/Galileo at the same time.  Personally I'd wait to see a "review involving OSM-based map use" before getting one, but I'm sure they'll appear fairly soon.

Other non-Garmin options for "something to last all day" might be an old phone with GPS in it and user-removable batteries.  An old Blackberry might be an option (they still work after you manage to drop them on the floor, and you might find the keyboard more usable than a touchscreen when it's cold).

Best Regards,

Andy

* at the time this was essentially "free" due to availability and what stock the various discounters carried - in theory its about £60 extra, and probably isn't worth that.

Thank you, dikkeknodel.

I also received an email message with an advice to acquire Garmin eTrex.  I've ordered the Garmin eTrex 35 Touch with the pre-installed «TopoActive» Karte Europa, which is based on the OSM data, as I understood:
https://www.brack.ch/garmin-hand-gps-etrex-touch-370929

It supports the EGNOS, European Geostationary Navigation Overlay Service, which is supposed to correct the GPS signal. I have no idea how it works in reality. It also has got the GPS and barometric altimeters.

Best regards,

Hi all,

 

Thanks for all the great advice. I’ve looked into uMap and it does the job perfectly. With all the gpx of over a year of hiking imported it still runs smoothly.

I would like to prevent running into performance issues later though. Does anybody know if it is wise to add ‘simplified’ versions of the gpx to uMap instead of the original recordings with 1 s resolution?

 

Since the published data is public, I just have to take into account not to import gpx which start from my home since I value my ‘sort of anonymity’.
