Application of OSM data

Taking these questions one at a time...

I want to have a viewer to read the map on PC

I'm presuming here that you want to do something with the data rather than having a map that looks just like the OSM standard map on your PC (after all, you can do that by just opening a web browser). If so, I'd start by looking at the "rendering" wiki page and probably Maperitive.

is it possible to combine the Vector from Open Cycle map and OSM?

Not directly. The Opencylemap is created by combining OSM data, other third-party data (such as SRTM height info) and a lot of hard work. You could do something similar, but you'd have to combine the data yourself. From memory at least one worked example on the Maperitive site uses contour data though.

I want to add routes, checkpoints on the map too, which software should I chose on PC Platform?

It depends a bit what you mean by "routes". For example, I will at some point this summer walk from here to here, but as the route exists nowhere but in my own head (or as a series of waypoints on a GPS I'll be carrying) it doesn't belong in OSM. However, as some point in the future I'll also follow the Viking Way north from here. That does belong in OSM, because it's signposted on the ground.

If what you're talking about is a route of the first sort not the second, then I'd have a search through the OSM wiki (category software) and this help site. You'll find a lot that targets specific GPS units (specifically Garmin - proprietary software such as Basecamp and Mapsource may meet your requirements). I'm sure that people will chip in with other suggestions.

I have tried JOSM, but it's too large to open it

Just checking, but you're not trying to open the 21Gb of OSM planet that you downloaded in JOSM are you? If not, how much RAM does your PC have?

To download just a small area in JOSM I'd do the following:

• File / Download from OSM
• Enter the placename I'm interested in and click "search"
• Click on the entry I'm interested in in the search results and click "download"
• Fetch the imagery I'm interested in using the "imagery" menu.

If you haven't already seen it, have a look at the beginners' guide pages, particularly the editing ones for Potlatch and JOSM.

I found it there is many line and points,but no names

I'm guessing that you're talking about an area such as this one (that's actually a suburb of Bulawayo, Zimbabwe). There you can see lots of residential roads, and you can see (by editing the map or by browsing the map data) that they've been tagged as "highway=residential", "source=Bing" - someone's just traced the roads from the Bing imagery. If you're dealing with a place like that, and you know the names (e.g by reading street signs - not by copying from another map) then go ahead and add the names. What might be helpful, though, is if you could post a "permalink" to the area as a comment to your question, so that we know what area you're talking about.

Hi Jason, don't worry, there is always a solution.

I am a newbie, but i like to share my little experience i have made.

to 1)...i am no expert, can not tell.

to 2)...For online editing use Potlatch2, for offline editing use JOSM

to 3)...try this: java -jar -Xmx512M josm-tested.jar to use more of your RAM. Download just the area you want to work on (few square-miles).

to 4)...if you know the names go ahead and edit the information, others will thank you.

In general, get rid of windows, use Linux (Kubuntu) to accelerate the performance of your pc.

happy mapping - wunderlicht
