I’d like to work offline, on a city map (in Israel). For doing that, I’d like to download a city map with it’s transportation data, street names and all city data available.
I downloaded a map, a very high resolution map, but only in PDF, and it includes only the main street names all other street name are shown on the map on the OSM site. Looks like some of the layers are not included in the downloaded city map. Maybe I need to add a font?
I also tried to download, for example the transportation layer which is shown on the site, but the recieved map is the same main map, mentioned above, without the additional data shown on the web.
Can anyone tell me how can I down load in PNG, but in a high resolution, and I can improve the download and get also the data layers?
Technically only the data layer is the the map.
The easiest way of doing this is probably to use JOSM, and save the layer. JOSM will render a map suitable for editting (in a choice of several formats) so most people will not need a separate rendered image. As such, I’ve never had to research how to deal with imagery offline, but you may find that simly providing a cache directory that is permanent will help, and you can always download a range of tiles and serve them locally.
JOSM can also reconcile the local copy with the defnitive version and merge changes with manual conflict resolution.
You can, of course, use the export features on the main web page to download the data.
first: The OpenStreetMap data is a single database that is NOT organized in layers … If you want to use the word layer, then all OSM elements are on one single layer.
second: you can of course download OSM data for a special area and that already filtered by desired elements like POIs or nature elements or ways. when loading those data portions for example in QGIS or JOSM editor, you can organize OSM data in layers on your own.
third: please always diferentiate between pure raw OSM data, and then to OSM based map graphics … that are two own standing things, because you can download from the one main database, but display that data in many ways.
see the OSM wiki about http://wiki.openstreetmap.org/wiki/Rendering
and browse our FAQ site https://help.osm.org … try different key words there like export, filter, print, paper, PDF, SVG etc.
