Hi there<br><br>I am pasting below a comprehensive answer to the questions raised in this thread by Talbot Brook (Mississipi Sate University) to whom I had forwarded the whole thread which as you can read clarifies all the points earlier questioned.<br>
<br>I'd like to hear back from the list about the interest for printing in the US and shipping to Haiti large quantities of such a field/ on the ground oriented high quality product for wide dissemination with a specific attention to reach the poorest of the responders (with no/ limited access to computers and internet access) and the poorest tout court: the Haitian.<br>
<br>I hope Talbot's email clarifies and look fwd 2 hearing back on the piece above.<br><br>Best.<br>N<br><br> Nicolas -<br><br> I'm not sure where the confusion is arising, but would like to help clear it up. We clearly state on the legend page and each individual map page that the street data is from OSM as downloaded using GeoFabrik. Further, as specified, the imagery used is by GeoEye as downloaded from Google. USGS has not contributed any data to these products other than serving as the source for downloading the ASTER DEM which was used to derive contours in some products. The date of the data would be the date of the map - this is pretty standard stuff. I would strongly suggest that the OSM folks not digitize and name from these maps as they are the original data source and where no names are listed for streets is more likely a function of the label manager in the software we use than the absence of labeling - too many labels renders the map useless. We had been using the Minustah data for points as indicated, but given the thread, am worried that some OSM point data may have been mixed in by one of my technicians - I will have to check.<br>
<br> While the directories being sponsored by USGS may be confusing at first, they're likely pretty straight forward to a trained map user who knows MGRS (I hope that didn't sound condescending as it's not meant as such!!!). These are scaled map products for use in print-and-go and to supplement GPS. They are organized by MGRS coordinate - the zone designation, the 100,000-m square ID, the 2-digit easting and the 2-digit northing. Thus anyone knowing where they are or wanting to go to specific area can immediately pick out the right map, or if they like, download the entire series for use.<br>
<br> If we've made an error or this is causing too much operational confusion, please let me know pronto and I'll do what I can to resolve the issue. We're trying to recognize that while online map services are great, they're not very good for those going to the field - portable maps with coordinate reference systems are a requirement -- we've made every effort to follow the cartographic and navigational standards that will be used in the field by military, US SAR assets and similar.<br>

J-G forwarded a message that included a link to the USGS maps. The message was in response to someone looking for an updated street index, and it spun off from there. If we need further confirmation, user osmapb1--oh, that's Adrian--has gone and checked 9 areas and found no differences. So, yes, I'd recommend removing it. Plenty of other things to work on! (if noone else does it in the next hour or two, I'll do when I have another chance).<br>

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. <br>
<br>
Should we simply remove the whole section from the wiki? <br>

any other data, it would probably be from MINUSTAH, but that's already

<br>
I had trouble understanding what these were too. The pdf's are from
Delta State University (<a href="http://edcftp.cr.usgs.gov/pub/data/disaster/201001_Earthquake_Haiti/data/map_products/MISSISSIPPI_DELTA_STATE_MAPS/Haiti_25Kand6Kcombo_lettersize_GeopdfimageAtlas_vDSU20100119/" target="_blank">here</a>) and represent the difference between the
road names on the USGS maps and the road names on osm.<br>
<br>
Names present on the USGS maps but NOT in osm are highlighted in black.<br>
<br>
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.<br>
<br>
(And that doesn't include the work of actually putting names into osm
when they are found)<br>
<br>
As each pdf is done it needs to be commented as such.<br>
<br>
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.<br>

<div> Hi Adrian<br>
<br>
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)?<br>
<br>
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?<br>
<br>
Regards<br>
Karl <br>

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.<br>
<br>
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.<br>
<br>
Can anyone say which of these has been done?<br>
