Open Street Map Help

Postby philm » Mon 11 Dec, 2017 12:40 pm

Hi Everyone
Apologies if this information is covered elsewhere but I have looked and can't find details. In Open street map are there any instructions on how to download a track that is on the map and also upload a track to update Open street map. When I go into the Open street map in Tasmania I see a track that I want to download then hopefully use in a Garmin GPS. Are there any instructions that are easy to follow?

Hi philm,

Where is the GPS track that you are interested in? Is it on the OpenStreetMap website? Or perhaps it is in an app or webservice that is displaying the track on top of an OpenStreetMap render? If you can post a link, I expect we can help you.

There are a few sites that allow download. Most are in formats to use in GIS programs like QGIS (Free and open source)

https://www.openstreetmap.org/export

Zoom in to the area and then hit the export button. This gives an map.osm file which you can then drag and drop into QGIS. From there you can do lots of things.

To edit a track or add a new one you will need to have an OSM login. https://www.openstreetmap.org/user/new

After that you can use the ID editor to add a new track and give it the required tags.

Contact me offline if you need help
Cheers - Phil

There is also the HOT export tool which gives the ability to download in formats like img and kml. I would advise zooming in to a particular area and ONLY selecting the tags required. Its a bit more complex to learn.

They also have some good documentation. https://export.hotosm.org/en/v3/learn

Some exports do not include paths (walking tracks)...path=yes

Hi Philm,

You can't really download a track from OSM. Exports are normally done for a bounded area and you get everything in that area. If you want to load OSM tracks onto your GPS you'd be better off getting hold of a Garmin img map built from OSM data. There are several sites that offer various OSM img files. I have made my own which you can download from here: http://tiny.cc/osm-maps. There is a map for each state. Tas and Vic are the best as they include contours and watercourses sourced from TasMap and VicMaps. OSM does not include contours and watercourses are poorly mapped. These maps would be used instead of your current base map (maybe Garmin Aus Topo). You can have them both loaded on the GPS and select which one to use.

If you want to add/edit OSM you can download JOSM. JOSM is a java app. There's a bit of a learning curve, but the basic procedure is to download (using JOSM) the area of interest, make your changes and upload back to OSM. There is also an online web browser based tool for updating OSM, but it has been a while since I used it. I forget the name, but it should be able to find it on the OSM website. The changes will be visible in OSM in a few hours.

Cheers

Getting a track/route as a gpx file:
If it is considered to be a 'way marked route' within OSM 8) then you can download it from
https://hiking.waymarkedtrails.org/#rou ... 3!147.6049

Note the right panel with the routes.
Click on the route you are interested in and it will open up some options - such as gpx download, and elevation profile.

That help?

Updating OSM with a gpx file:
Best to do this yourself. Register with OSM and learn how to do the bit you want. You don't have to learn all of OSM .. just the bits you want to use.
Takes some time for the map makers to use the new data - 1 to 2 months is the usually time lag.

Thanks for your help everyone

I am trying to export the track from the following map

http://www.openstreetmap.org/export#map ... 6/146.2030

The track runs from the end of Mersey Forest Road through to Junction Lake Hut.

I had a look at https://hiking.waymarkedtrails.org/#rou ... 3!147.6049 and it does not appear to be a trail?

Any suggestions on how to extract the track details?

It may not satisfy the OSM definition of 'way marked' or simply not have had the added information included in OSM.

There are several bits you want there ;
http://www.openstreetmap.org/way/189337 ... 5/146.1808 Way: Moses Creek Track (189337309)
http://www.openstreetmap.org/way/244110 ... 1/146.1812 Way: Moses Creek Track (244110966) {source GPS so that makes it different from the above}
http://www.openstreetmap.org/way/247573 ... 6/146.1789 Way: Moses Creek Track (247573489) {don't know why this is different from the above}

So that is 3 bits.
Download each of the .xml files (scroll to bottom of left screen panel).
This gets you 3 files in OSM .xml format

Now use babble to convert them to .gpx format
https://www.mapsmarker.com/docs/pro-ver ... rack-file/

That should work. :?: NO it does not - OSM does not do the right thing.. not dowloading the node lat/longs :oops:
You may have to go the JOSM route and down load the above ways and export them as gpx from there.

Like tastrax says, direct export from OpenStreetMap is geared up for use in GIS programs. QGIS is free and powerful, but it's a complex piece of software and will take time to learn.

Here's the approach I would take, to turn a track that is mapped on OSM into a downloadable GPX file:

1. Go to gpsies.com
2. Register an account and log in
3. From the "Create" menu, select "Track Creator"
4. Make sure you select "Follow Roads" on the right-hand panel
5. Scroll/zoom the map to the bit you are interested in
6. Click roughly along the route. The website will follow the track, so you only need to click at junctions and at a few intermediate points and the website will fill in the other bits by following the map.
7. Click "Save". Now this route is stored in your Gpsies account, and you can export it to your computer as a GPS with various options

In your initial post, you thought that you might want to update the track on OSM (presumably after you have walked it and recorded its route). After each bushwalk I tweak the map to fix errors or add more features, and this is how I do it. There are plenty of other ways that suit some people better. I prefer to use the in-browser editor for all straightforward edits.

1. Put your GPX trace on your computer
2. Register and log in at OpenStreetMap.
3. Go to the OpenStreetMap website and scroll/zoom to your area of interest
4. Click "Edit" and from the drop-down select "Edit with iD (in-browser editor)", then give it a few seconds to load
5. Click the "Help" icon (the bottom of the right-hand vertical toolbar) and read it all (it's brief, and includes a guide to editing roads/tracks)
6. Click the "Map Data" Icon (second-last icon on the right-hand vertical toolbar).
7. On the pop-out panel, locate the "Local File" line and click the arrow on that line to select your GPS file and display it on the map.
8. Now you can see the aerial photo in the background, then the map features, and your GPS trace on top.
9. Edit the track by hand to match the background photo, your GPS trace, and your survey notes.
10. Click "Save" and add a brief description of what you have done.

There are fancier ways to do this, but I prefer to manually edit the track because my GPS tracks tend to include glitches that I would not want to automatically transfer to OpenStreetMap.

Additionally, after saving my edits, I like to upload my GPX file to OpenStreetMap as a show of good faith that I have been to the area, and to assist future mappers. Click the "GPS Traces" link, then "Upload a trace". (If you want to display other people's uploaded traces while you're editing the map, there's an option for that on the icon that looks like a stack of papers, but it slows down the map rendering considerably.)

Here are all the AS2156 tracks in Tasmania compliments of the Open data available from LISTMAP - I made them as KML as most folks can use that in Google Earth

http://listdata.thelist.tas.gov.au/opendata/

Whoops - too big for the site so loaded here http://wyatt-family.com/wyatt/temp/Trac ... 017_12.zip

http://tiny.cc/osm-maps still has downloads for each state, albeit somewhat older

The usual sources for OSM garmin maps are oriented for car divers .. so you have to zoom in to see bushwalking tracks.
But they are updated more regularly ...

http://garmin.openstreetmap.nl/ -updated ~ once a month. I like the 'new style' version.
http://alternativaslibres.org/en/downloads.php Daly updates! No one really needs them that quick?

If you are simply looking for the changes made by some edit you have made to OSM then that happens fairly quickly on what ever editor you are using .. when zoomed in.
If your making changes on large areas .. those don't come through for quite a while.

For Oruxmap app this one currently seems quite good?

Add Contours & POI as overlay in maps dropdown if desired
