I wrote (guessed) part of what is on the wiki because there was just this list of PDF documents and no furthern info. I'm looking for confirmations/corrections from people who are actually involved in producing these maps. Discussion was to complete OSM data from the USGS maps but the way it looks now it doesn't make a lot of senset to me. And no, I didn't find any name I could have completed when I had a closer look at three samples areas.

Should we simply remove the whole section from the wiki?

Is the whole thing on the wiki just wrong? I haven't looked extensively, but the street names appear to match up. This would make sense as the map says "Street data courtesy openstreetmap.org <http://openstreetmap.org>" If there were any other data, it would probably be from MINUSTAH, but that's already mentioned on the OSM Street Names page. Has anyone seen a specific example of where the USGS maps have more street data than OSM?

    Hi Karl,

    I had trouble understanding what these were too. The pdf's are
    from Delta State University  (here
    
<http://edcftp.cr.usgs.gov/pub/data/disaster/201001_Earthquake_Haiti/data/map_products/MISSISSIPPI_DELTA_STATE_MAPS/Haiti_25Kand6Kcombo_lettersize_GeopdfimageAtlas_vDSU20100119/>)
    and represent the difference between the road names on the USGS
    maps and the road names on osm.

    Names present on the USGS maps but NOT in osm are highlighted in
    black.

    That is very useful, but there are roughly ninety docs with twenty
    (image) pages in each giving 1800 separate comparisons to be made.
    Also, updates will have been made to osm, from other sources,
    since the extract. So if a name is in black in the pdf but now
    present in osm that still does not indicate whether that area has
    been done or not.

    (And that doesn't include the work of actually putting names into
    osm when they are found)

    As each pdf is done it needs to be commented as such.

    I'm happy to start on the job but want to wait for some time in
    case anyone has already done some of the work. We can't afford to
    do such large amounts of work twice if we can avoid it. It would
    make sense to work outwards from PaP but it is the towns where the
    comparison is most laborious/time-consuming.

    Regards,
    Adrian.

        Hi Adrian

        I also had a look at these maps and I still don't understand
        completely how they relate to OSM. The map already displays
        the OSMs road network, but where do the street names in the
        USGS map come from? They aren't taken from OSM, are they? Are
        there indeed two road networks in the USGS map, one in maroon
        (from OSM) and one from an unknown source (in black)?

        For my taste, navigation in the PDF atlas is too complicated
        (for mappers, people in the field may find it useful) and
        comparing the street names manually with names displayed on a
        slippymap in another instance is way too complicated too. Are
        the  USGS maps available as tiles served by a WMS server?

        Regards
        Karl

        Wiki page

        http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/Street_names

        contains a section called "USGS map areas with street names"
        which contains a list of pdf's with osm data overlain on USGS
        imagery with streetnames missing from osm at the time of
        preparation highlighted - these need adding to osm.

        There is nothing to indicate in the wiki which, if any, of
        these have been looked at systematically. Checking several at
        random has not told me which have been done and which
        haven't, except for the last page which has the "No named
        streets in this section" comment.

        Can anyone say which of these has been done?

        Adrian.
