relationship of locations between Mapsource and OSM

Hi,
you can convert the coords using proj/cs2cs and some perl scripts....
do you have any datafiles? post them somewhere, archive.org is good.

40 gps devices to be sponsored to train a OSM team for kosovo

Thanks guys, I have to say that this was managed by Arianit Dobroshi, Bresta , and the whole flossk team. I will pass on your congratulations.

test of osm splitter over torrent. please peer!

Thanks!
the plan is to update the seeds daily, We will extract the data from http://download.geofabrik.de/osm/ here on a daily basis and update the seeds.
this is just an experiment. But thanks for helping!
I am interested in what type of speed we can get and how many peers we can find.
The next step will be to make some form of decentral updating as well.

thanks,
mike

    fixed it, just removed the offending line from the file :

    update data did not help, here is the file.

    wikiptravel removing links to openstreetmap

    Yes, they have a special way to link wikipedia.
    I give, up, really I dont care about wikitravel. if they dont want links, they dont get them. meh

    wikiptravel removing links to openstreetmap

    They have a special exception for wikipedia, but not for OSM. I would like to undestand why.

    wikiptravel removing links to openstreetmap

    Well,from what I saw, it would be ok. OSM is not a travel site, it is a mapping site. the license is compatible. etc. My feeling was that the link was removed because it was a link, not looking into if OSM fits the policy. my reading of the policy would allow links to osm. Of course I can be wrong.

    wikiptravel removing links to openstreetmap

    Yes, they have detailed instructions on how to export maps from osm for usage there. But they are still removing the LINKs to osm. I would like to have a link from shkoder to the wikiproject shkdoer.
    thanks,

    Meeting results from Vermessungsamt and suggestions for local government on Openstreetmap

    NICE! no I did not see that one yet. thanks

    create openstreetmap way links in inkscape patch

    Here this changeset here :
    http://www.openstreetmap.org/browse/changeset/4362442

    was derived from this photo here :
    http://www.flickr.com/photos/tonythemisfit/2443746612/

    create openstreetmap way links in inkscape patch

    Well, here is my plan :
    1. be able to take the osm id from the clipboard (in josm ctrl c on an object) and create a link to that way.
    2. be able to download the geometry of the osm object and add it as attributes of the object.
    3. be able to assign geometries to points as well
    4. be able to determine the coordinate of new items from the existing geometries (a 3d grid)
    5. be able to copy new items from inkscape into josm

    The idea is this:

    if you know the fixed point of some items, and you know the relative positions of others from the photos, you can add in the new relative items.

    If you have a row of houses along a street, then you can just add them in to osm one after another to fill up the street according to the geometries of the photo.

    Then if you have them tagged on the photo, it should be possible later to do some type of sanity check on the coordinates, each pixel will have some type of size associated to it, according to the geometry of the map.

    You can then pull the information back from osm, into the photo and check them, does the size of the house match the box on the picture in any way?

    In any case, this is what I have been experimenting with.

    Even if we dont have software to do this, we have brains, and our brains should be able to check the relationships.

    You can see this area of the map
    http://www.openstreetmap.org/?lat=41.989812&lon=20.705707&zoom=18&layers=B000FTF

    All those houses I added in from the photo. and you can see the graveyard and the streets as a point of reference. Even if they are all shifted off in some direction we can fix that when we have more data.

    If you add in all the buildings then it is then a matter of verifing them. But 10 buildings that fill up a street will have to have some type of even spacing to them.

    Wikipedia full of copyrighted, unattributed maps

    My suggestion is that we introduce a new tag into wikipedia and a new marker if the data is usable under UK or US copyright law. Then we would know what information is usable at all. Right now the maps and points in WP are not really sourced at all.

    If you look at the difference between these two pages, you might think that WP is encouraging people to use google maps :
    http://wiki.openstreetmap.org/wiki/JOSM/Plugins/WMSPlugin#Licensing

    http://en.wikipedia.org/wiki/Geographic_coordinates_%28obtaining%29#On_the_web

    Wikipedia full of copyrighted, unattributed maps

    Well, these are maps. Wikipedia is full of maps that we cannot use. Also wikipedia have systematically collected millions of datapoints from google maps.
    The google map is still the preferred source for geohack.
    How can that work? Only because google tolerates it or there is some legal basis to it?

    new version of osm2blender 3d export working

    Umm,
    I did not see any source code for that tool when I looked.
    if I had a nice payed university job to finance my work, then I guess I would not be able to contribute the results.

    Please I dont care about the non free programs that do great things, why dont I point to google earth and say : oh why dont you make josm more usable?

    my proposal for an #restrictedstreetmap like the debian/ubuntu restricted packages section for tracing geoeye and other sat images FTW

    we can look for streets on restricted maps, and then use that information to scan those areas on the landsat and yahoo maps for confirmation. that would be a 100% legal use of a restricted map. dont you think?

    my proposal for an #restrictedstreetmap like the debian/ubuntu restricted packages section for tracing geoeye and other sat images FTW

    OK!
    well wikimapia is one such project.
    Also the data derived from that could not be fed into osm, but it could be merged into a new derived work that has both datasources in it, like roadmatcher.

    The point is that there are so many such datasources available, at least we could have wms and wfs layers, searching and other tools available for them.

    In fact, the only thing that I am interested in is contours and polygons that can be extracted using gdal. that is what i would like to have.

    We will have to go into what is fair use, what information is it legal to use in comparing streets. I think that it is for educational purposes possible to fairly use some data. There must be a way to do some clean room reverse engineering of the comparison data. For example, use that information to find public domain references that would collaborate the facts.

    if you know that this street is off, and then find 10 web references to support that information, you could write a paper about that steet comparing the all available sources, giving its history etc.

    that might be fair use.
