Talk:Upload
Discuss the Upload page here:
See tags
It would be more usefull to see (by a click on the Track) the Tags of the Track that I uploaded. So if I make a Track on a Motorway I can the, when I´m Editing, that it is a Motorway. --S sommerkamp 20:45, 23 March 2007 S
how and why tag the gpx file
The page need an explanation of how and why tag the gpx file. -- Espen 17:37, 24 April 2007
What is the purpose of Tags on uploads?
What is the purpose of upload tags and what is the proper format for entering them? --User:Gowen 14:35, 25 June 2007
- Tagging section has since been added. Does that clarify things? -- Harry Wood 16:19, 15 October 2007 (BST)
Define some common tags for GPX files ?
IMO it would be good to have some common tags for the GPX files - even if they are not used at the moment.
E.g.
- which vehicle that was used to create the track? (car/bike/foot)
- Is the track recommended for certain vehicles? This information could e.g. be used by a router algorithm for bicycles. Likely a lot of people just add tracks of their preferred ways and not tracks that aim to cover may streets.
--Grungelborz 20:50, 24 October 2007 (BST)
- Yes. Seems like it could be a good idea to list some suggested tags on the page here. Or even show a 'Tag Cloud' -- Harry Wood 17:20, 8 January 2008 (UTC)
Please create some compulsory tag that sets the vehicle. This could be set in a dropdown menu. Possibilties are: train, street_vehicle, bike, foot, boat, agricultural, ski, mixed, unknown. Then there should be different rendering styles in josm so e.g. cycleways can be easily separated from streets. Users should be notified to set the vehicle of former uploaded traces. -- Travelling salesman 18:10, 17 September 2011 (BST)
Take care of the file format
I wanted to upload my first gpx-files. After a few minutes I got an email with a failure-message. After some tests I found the problem. I created the files using a Linux-OS. The files were saved in unix-file-format. After I converted them to DOS-file-format (using unix2dos) the files were accepted.
I think, this is the most important part of the failure message:
Bad file descriptor - /usr/bin/file -bz /home/osm/gpx/94495.gpx
--JoeBresale 12:50, 11 April 2008 (BST)
This seems not to be a problem anymore. My files with '\n' as line separator work well. --Plasmon 10:24, 1 March 2009 (UTC)
Existing/GPS tracks
I just did my first driving while logging tracks. They seem to be off of the existing data, which is from TIGER data. I'm going to assume that I just move the existing points to be where my GPSr recorded the points. Should I do differently? — Val42 06:26, 21 September 2008 (UTC)
- If the logs show the geometry of the roads correctly (notably straights as straight) the logs can be more accurate; you might wish to log a second and a third trip on different days (a few blocks might suffice) because constant 5-15 meter offsets in reception are possible on what i'd call a bad satellite day. Remember also that the location of your GPSr was probably not on the road center line but 2 to 11 meters to the side depending on the number of lanes in your driving direction (1 to 3) and their width. I've read already before comments that the tiger data has been found to be offset in places, so it shouldn't be unusual to move them but I'm inclined to believe they have the shapes right - as of the past date on which they were collected. So if your log shapes seem right and the offset is bigger the logs are most likely more accurate. Alv 09:11, 21 September 2008 (UTC)
- Yeah there's a little paragraph about that over at TIGER fixup#Accuracy: Offset from reality, but I'm not sure what the recommended procedure should be regarding gathering multiple GPS traces on different days. -- Harry Wood 09:45, 21 September 2008 (UTC)
Upload with JavaScript
Is it possible to automatically upload a trace using JavaScript? How would I do that?
Public!?
What does the public option for uploading my traces mean? There seems to be no description in the wiki, at least I expect one on this page. Thanks a lot. --Plasmon 21:35, 22 February 2009 (UTC)
- Somebody created a new page: Visibility_of_GPS_traces. Seems to be fine now. Thanks! --Plasmon 20:56, 2 July 2009 (UTC)
Upload your own maps or aereal photo in Potlatch
In some areas, the aereal photo from Yahoo are not in a high resolution. I would like to trace from maps I have. This is easier and more exact with a pencil on trace paper then with the mouse on the screen.
- It would be helpfull to have a function to upload my own background image (as a .png for example) to trace it in Potlatch. It should be possible to fix a point and to strectch the picture to rescale it.
A "save the image"-button is not possible, 1st, because after traving, I do not need it anymore (or I have to upload it again); 2nd it does not need storage space on the servers from OSM; 3rd to avoid any problems with the different copy rights.--Männedorf 10:29, 28 February 2010 (UTC)
- I found the solution my self: There is such a tool: Walking Papers at http://walking-papers.org
- You download the section of OSM you like. Then you add what you want, scan the paper and upload it as a jpeg-file. Then it is avaible for Potlatch (online) and for JOSM (offline).
- With a software like Gimp (or Photoshop, if you like to pay for it), you can also stretch a areal view or a map you made on your own and mearch with the downloaded map. Walking Papers is available in the following languages: English Deutsch Nederlands Español Français 日本語 Italiano --Männedorf 20:16, 28 February 2010 (UTC)
Is UTF-8 mandatory?
Unfortunately, not everyone's computers are set up to use UTF-8 by default, so some people are generating GPX files with other encodings, such as ISO8859-1 or windows-1252. I've heard that uploading these to OSM results in an error message, can anyone confirm this? Does OSM-upload *only* support UTF-8 encoded gpx files? And if so, what's the recommended way to convert such a non-compliant file to UTF-8 so it's acceptable for upload? Eric2 21:34, 12 April 2011 (BST)
Accuracy data
It seems like the accuracy data (horizontal accuracy expressed by <hdop>value</hdop> in the gpx) is somehow not present after the upload. I have accuracy data in my gpx and JOSM draws the circles very nicely, but when I upload a track and then download the data in the corresponding area using JOSM there are no circles. Maybe someone can get this straight: is the data droped during upload and therefore not present in the DB or is this a JOSM-related issue? greetings --DerKuchen 23:20, 7 June 2011 (BST)
- If you view your trace on your traces list, and use the download link there, you'll see we are preserving things like <hdop> tags in the file uploads. Example: http://www.openstreetmap.org/user/EdLoach/traces/896103 ...however the data which is inserted into the database, by parsing the file, has data like this stripped out yes. It's not a field we keep in our database, and it's not something which gets returned when you're downloading a bounding box of GPS points (from any and all users in the area) via the API into JOSM. If you want to see your HDOP circle, you have to load the GPX file in by opening it as a local file into JOSM. -- Harry Wood 12:54, 9 June 2011 (BST)
