[OSM-talk] USGS map areas with street names

[Adrian Brain]

Hi Karl,

I had trouble understanding what these were too. The pdf's are from Delta State University  (here) 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.
