Re: [Talk-GB] Finding Unmapped public rights of way
Hi I'm trying to make use of the row files on rowmaps for derbyshire and staffordshire and and merging these with and osm map file to then produce maps that can highlight which paths are and aren't mapped. I can put the derbyshire file into JOSM and download parts of the area and merge them to create an osm file that I can then save locally and import into Maperative. A modified rules file allows me to produce the prow footpath ways and the osm footpath ways as different coloured dotted lines so I can see which are/aren't mapped. Unfortunately JOSM doesn't seem to be able to cope with merging large files. I maybe asking to much of it as the files are quite big. What I would like is to be able to get a merged file of the derbyshire, saffordshire row files and the equivalent osm map file on a regular basis (highlighting the rows that aren't mapped) so I can slowly pick away at the remaining footpaths the need mapping in this area. Does anyone know of a simple way to do this? Many Thanks Dudley ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Finding Unmapped public rights of way
Hello, If you are just wanting to visualy inspect them, could you do it in TileMill. I produced a map of a large part of County Durham that showed both OSM footpaths and PRoW differently coloured. It produced a MBtiles file which I then converted to Z,X,Y PNG tiles I then added that as a source into a local OpenLayers site which allowed me to view it from any browser. You could convert it to another map format with Mobile Atlas Creator and view the map that way. You could even use the produced map as a background in JOSM if you then want to trace the paths? You could also do it in QGIS and could probably get it to highlight only the paths that are missing. Not sure if either of those is exactly what you are after.

Re: [Talk-GB] Finding Unmapped public rights of way - SOTM topic?
Hi both, Those are some really neat ideas! I hope you are thinking about sharing them at State of the Map in September ;-) We have a theme of change this year and one of the areas I am interested in is how we manage external data sources. Public Rights of Way are a great example as it poses several questions: 1) How do we check that we have included all the PROW routes in OSM? This is complicated by the fact that our way may not have exactly the same geometry as the external data's polyline. 2) How can we monitor for changes in the external (Local Authority) data/shapefiles? 3) Where can automated tests help, and where is manual intervention always needed? 4) Can we make use of the Cycle Paths merge functionality that was added to Potlatch 2? I would love to hear more about this at SOTM 2013. We have some lightning talks slots and can also print posters for you [see link below]. Perhaps this would make a good poster? http://2013.stateofthemap.org/info/call-presentations/ Regards Rob ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

Does anyone know of a simple way to do this? Depends on how big the files are, and how much memory you have on your computer. You can assign more memory to JOSM, which might help. eg run it with a command like this: java -Xmx1500M -jar josm-tested.jar That would allow it 1500MB. Or for merging large files, you could use Osmosis. http://wiki.openstreetmap.org/wiki/Osmosis ie use a command like this: osmosis --rx file2.osm --rx file1.osm --m --wx merged.osm Craig ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
