Thanks this is good news. I uploaded using JOSM (Macintosh computer) but nothing has changed so obviously I did something wrong. I also have no idea what Potlatch is yet.
I didn’t do any conversion in JOSM. I just did the corrections, added the roads and places from my Nuvi 265W and uploaded the folder containing the roads and locations.
I need to learn a bit more and try again. I used to love complicated gadgets but at 65 my brain and memory are not so good as they were and the terminology here is all different to what I am used to.
My internet connection is not good at all but what I am uploading is not a very big file file.
I don’t understand what you say about uploading a “folder with corrections”.
When I use JOSM, I:
Download an area to work on from JOSM.
Make additions or corrections.
Upload corrections from inside the same JOSM session when I’m done.
If you upload from inside the JOSM session you should get a dialog box identifying which items will be uploaded (only the changes will be uploaded) and see a progress bar during the upload.
Potlatch is the on screen editor you get when you click on the “Edit” button on the main map display.
I’ve got a fast fiber connection here in the US, so I don’t know what to expect if you get transmission errors, but I do know that sometimes the server gets cranky.
Thanks. I think I did everything the same and I did get an upload progress bar and confirmation so it may be the server lost it. I will try again today when I have prepared the tracks I did yesterday.
I doubt if the connection speed is a problem because what I am uploading is not huge file sizes. If I upload using JOSM does it still show up almost immediately so I can see if it was successful?
If I add/edit OSM data, by whatever method, how long does it take my additions and edits to show up in the downloadable map created by Lambertus?
Perhaps I can offer a partial answer. I downloaded two Thailand tiles today (October 5, 2009) from Lambertus. Edits that I made on September 7th show up. Edits that I made on On September 8th and following do not.
Thanks I am starting to get the hang of it. Today I reloaded the tracks from my GPS into JOSM but instead of just uploading I used the draw nodes tool to trace the tracks and correct minor errors. Then I uploaded.
I quit JOSM and then opened it again and downloaded the map again. The roads I added are there with grey lines but when I download the Philippines tile for my GPS they are not there so I assume from this they will show on the Philippines tile after Lambertus has checked and approved or copied to the tile or something.
If I am sure I am doing it right I will continue mapping more roads and places but I don’t want to do too many hours of work and driving only to find it is wrong and I have to start over again.
I got errors saying the tracks were not named and there were no tags but these roads have no names yet so should I name them by when they start and finish, like “Del-Monte to Kaputian Road”? I don’t know what the tags are so I need to look for information on that. In JOSM there is just a grayed out “Paste Tags” in the menu.
With the JOSM and Potlatch editors you manipulate the OpenStreetMap database. A dump (copy/backup) of this database is made available every Wednesday (somewhere during the evening mostly). I try to download the this dump every week on Thursday and start rendering the tiles that you can download from my website. This takes a few days, so the following Monday a new version of the Garmin maps is released unless things did not work or big changes in the rendering tools are being made. So sometimes it takes almost a month to release a new version (like it did last month).
The thing that you need to be aware of is: The data that you see in your editor might not yet be visible in the OSM website slippy map (but will be within minutes after you hit ‘upload’ mostly) and it might take a lot longer for your edits to show up in third-party applications like my Garmin maps.
Regarding the freshness of the OSM data in the Garmin maps: the date of the OSM database dump from which the Garmin maps is rendered is shown below the map on the routable Garmin webpage.
Hi, the roads will not show up without tags because there is no way to know what the lines mean: they could mean administrative boundary, a dam, or a fence. You could set the type of road
highway=motorway
highway=primary
highway=secondary
highway=tertiary
highway=residential
but do this only if you know the road officially does not have a name. If the road has a name, but you haven’t yet gathered the name information, use just
highway=road
That allows the road to be drawn and routed. It is also an implied placeholder for future reference that more information will be needed to better map the road. It is better not to assign a name unless you know of the correct name.
In addition, there may be a delay between your uploading road definitions from JOSM until they are integrated into a new Tile download; I’m not sure. Some systems update daily - others update weekly or every other week. (There’s a huge amount of change data to process worldwide)
An good reference for tags is in the Wiki http://wiki.openstreetmap.org/wiki/Map_Features. “Paste Tags” is normally only used in cases where you need to copy tags from one item to another - such as after creating a new road that matches all attributes of another road.
But there is something more. I did not read about that in the forum.
A 60Cx will often show ??? for placenames in cyrillic characters. The question is where do these ??? come from?
Well they are already in the .img file. (gmapsupp.img or an .img file downloaded from …/routable.php. Today I downloaded 63240168.img).
If the .img file really contains cyrillic characters you will see not ??? but all kind of funny symbols.
Your Img files made with mkgmap contain ???. ( I have .img files here made with cgpsmapper that really contain the cyrillic text).
–name-tag-list=int_name,name:en,name
Is not enough because when int_name and name:en are empty mkgmap does not put the cyrillic characters (from name) in the resulting .img file but ???'s. This is -maybe- because these characters are not in the used codetable. If they are not in the table a ? is placed. Better would be to put the original value in the img file.
If the .img file contains cyrillic characters then a transliteration can be done to latin ones. This can be done afterwards on the img file itself.
If you download a map for the Ukrain from http://www.team-oid.de/garmin_maps/ then you get three .img files which contain cyrillic characters. I just put one of the files (72840001.img) in the 60 Cx and saw the funny symbols. Then I transliterated the file. Now the names are readable. These files are made with mkgmap too. How? I dont know. Maybe a cyrillic code table?
If I understand you correctly, under normal conditions the data I upload (with tags) will show almost immediately in the on-line map. It will then be included in the backup dump on the following Wednesday. Then on the following Monday it will be included in the downloaded tile.
Is this correct?
Many thanks for all the work you are doing.
P.S. Nobody who lives in the area knows of any names for the roads I am mapping so I am assigning descriptive names which are more useful anyway. Am I correct that I can change these names later if the roads are named and change the tags if the current tracks are paved? They are paving some of the roads now.
Yes, just keep an eye on the planet dump date below the map in the webpage where you can request the routable Garmin maps. Monday isn’t fixed.
No worries
If a road doesn’t have an official name then the local name is best ofcourse. If a name proves false afterwards then you (or anyone else) can change it.
That would be useful if the tile number en position would not change between updates, but that is not guaranteed in any way. So there is no use (imo) to make some sort of permalink.
there is no code page that suits every language (UTF-8 is not supported in many devices)
tiles often span multiple countries with languages that don’t match a single code-page
So a solution is to specify a code page for each tile but, since the layout of the tiles often differs quite a bit, this is not workable for me (I don’t want to spend all my spare time on the Garmin maps). So I chose to try to generate tiles that work in most cases and automate as much as possible.
Work is being done in trying to create tiles that line up with country borders which will make specifying different code-pages for each tile much easier. I’ll wait with different code-pages until there are country borders or another easy method (easy=automatic or possible to automate). Specialty maps are intentionally not my goal!
The reason for the strange overlap effect could be that you didn’t use proper rounding during the re-split. Coordinates in map units for the tile splitter (or mkgmap?) have to be rounded to eleven or so binary zeros.
From how I understand it: Splitter adds a bit more area then required to the split output which is why you see some tiles overlap now. Splitter also adds some information about the target area in the resulting osm file which is used by Mkgmap. If Splitter would use this information during the re-split as well then the problem would be solved. The maintainer of Splitter is planning to add this by the end of this month. That’s what I’m waiting for…
I don’t know if this has been suggested before but the search returned 0 hits.
I would prefer if the map (entire world) was downloadable as a torrent. I have lots of disk space and fast enough internet connection. I don’t know how much bandwidth usage you got on the server but if you got more than what the entire world is to download and enough people choose to download the torrent that should save bandwidth for you.
I’d like to have the entire world since it is such a lot of clicking to choose all the tiles i want each map update. Or is it fixed so that one can download only the tiles one need and keep the rest with the autoinstaller (.exe version)?
Yes, it’s been suggested before, but the search doesn’t work that well atm…
It’s a good idea and should be doable for the server. I’ll look into this.
But this is the problem… You can’t use an installer that came with another map from my site to install the whole world. So I probably should provide a torrent with all the tiles and also include an installer.exe that just creates the registry keys.
Don’t worry, the torrent thing is just extra: and link on the main page to the torrent. The rest of the site will remain the same.
Also, the update for this week is delayed: The planet dump from last week was corrupted and fixing it took much longer then expected.
Maybe you can answer a question for me.
I have added a lot of roads and because they are all unsurfaced I have tagged them as tracks. But - A large percentage of the roads in the area are unpaved even though they are sometimes relatively major roads by local standards.
Am I doing the right thing or should they be tagged as tertiary or something?
Well this is not a question for this topic, but a major road should have a major indication (like primary, secondary, tertiary). You can add additional information about the road characteristics like surface, quality, width etc.
