uk ordnance survey maps
 

Does anyone know a way of getting UK ordnance survey maps onto the N810? If I could find a way of saving digital OS maps as pdf files I could at least read them. The ideal would be to use them with the GPS.

Re: uk ordnance survey maps
 

What (digital) format are they published in?

I have got OS Maps working with maemo-mapper. All it takes is time and patience. If you have digital maps (i.e. memory maps) you would need to stitch together a number of screenshots first.

Re: uk ordnance survey maps
 

Thanks for these replies. I'm not sure what the format of the maps is since with all the software I have tried you can't save them in eg a jpeg form. The maps are available on Fugawi, Memory Map, Anquet Maps and Tracklogs. I will experiment with screen shots and see how I get on. Would that be using MS Word and then saving in a format which the 810 can read?

if you want to use maemo mapper, you will need to stitch a number of screenshots together in something like photoshop, to make a big jpeg. microsoft mapcruncher will then import this image and allow you to link the map to real-life, before exporting tiles in a format maemo mapper can use. this will allow you to use gps and zoom on the map

Well, this is amazing stuff! I've got my test map locked and rendered in mapcruncher, but there doesn't seem to be an export option to get it into Maemo mapper. Can you adivse?

Re: uk ordnance survey maps
 

once you've got it rendered you should end up with a lot of png images. These will need to be hosted on a web server somewhere. If you've only done a small area, your ISP may offer you some space. Alternatively, look for some free/cheap web space. A quick google turned up http://150m.com/ who will give you 150mb, enough to test with certainly. Once your images are uploaded, add a new repository to maemo mapper with a URL in the format:
http://www.myserver.com/tiles/%0s.png

replace www.myserver.com with the URL of your host, I've assumed you've got all your images in a tiles directory there.

Good luck.

Re: uk ordnance survey maps
 

This reply is a bit late, but it's taken me a while to get round this map business.

First off, for anyone keen on OS maps there is a very good source at http://www.mapyx.com/. You can buy decent sized map tiles much cheaper than the competition. The snag is they only export to standard mobile devices: either dedicated GPS or windows mobile.

However, it's quite easy to print each screen and save in photoshop, so will work well with Map Cruncher.

However I have been quite unable to get the "render" file from Map Cruncher to open in Maemo Mapper. I'm using Dreamweaver to put the file onto my website, and followed the instructions above to the letter, but nothing happens.

The "mashup" file produced by MapCruncher has the .xml suffix. Is this the right format?

Hope you can help

Re: uk ordnance survey maps
 

@twynog,

you don't need to do anything with the XML file. The only files you are interested in are the .png files generated by the render. I can't remember the exact process for the render, but it should take quite a while.

Re: uk ordnance survey maps
 

Well what happens is the render finishes and generates the xml file, then if you close the mapcruncher window it ask you to save the "mashup" as a.yum file.

Ive tried uploading this file too but get the same result in Maemo mapper - a black screen. It tries to upload maps from my repository but fails each time. I've tried getting crunching a map with my house in the middle of it and then going outside to get a gps fix, but still no joy.

This is so tantalisingly close! Any other ideas?

Re: uk ordnance survey maps
 

Are you generating a bunch of files called something like 00012345567.png?? These are the only files you need. Everything else is irrelevant. I'll re-run a crunch over the weekend (can't do it before then) and document the exact steps I take.

Re: uk ordnance survey maps
 

Here are step-by-step instructions for rendering images with mapcruncher

1. launch mapcruncher
2. add source map
3. map your points, the more the better. I like using points like railways crossing roads, or crossroads
4. under "source info" select max zoom - 15 is good for 50k maps, 16 for 25k maps
5. click "render"
6. select "render to file"
7. select an "output folder"
8. uncheck "Copy source maps and crunchup data to output folder"
9. uncheck "Permit composition"
10. Click "start"
11. wait, a long time for a big map area
12. in a folder called "Layer_NewLayer" under your chosen output folder will be a lot of .png files, (see screen shot)
13. upload these files to a folder on your web server (e.g. www.myserver.com/maps/tiles)
14. add a new maemo-mapper repository with the following url format: http://www.myserver.com/maps/tiles/%0s.png

Hope that helps

Re: uk ordnance survey maps
 

Wow - at last I can do it, and all thanks to you. If you feel like telling me how you worked out how to do it I would be very interested, but don't worry if you're busy.

The crucial bit of information was the file tree Layer_New Layer. I would never have thought of looking there.

One of the things that puzzles me is this: there are 49 odd tiles just for my home town (Llandovery). If I want to do the whole of Wales do you just keep adding .png files to the same folder? I guess you can set it to download only the tiles from the district you are actually in?

All the best and thanks again

Re: uk ordnance survey maps
 

@twynog,

Every time you do a new crunch, just upload the new images. There may be some duplicates created, but that shouldn't affect anything. Maemo-mapper will just download enough images to cover the current view and a bit more, or you can manually download a bigger area.

Re: uk ordnance survey maps
 

wouldn't it be nice if you could just grab the OS map tiles from say
http://openspace.ordnancesurvey.co.uk, merge, transform and crop them, and
then serve them up to maemo-mapper?

one might imagine this could be done with just 264 lines of perl cgi and it'd
be painless and slick and smooth and just ever so slightly against the terms
of service. which is a shame because it's very nice.

Re: uk ordnance survey maps
 

I've only had a quick look over the license, but if it's for your own use wouldn't it be allowed?

Re: uk ordnance survey maps
 

No, that's definitely excluded:
(my emphasis). So it needs to be a web-based application, and it has to be for third parties not just yourself. Also in the FAQ they say it "must be used within a publicly accessible application".

Re: uk ordnance survey maps
 

ok - here's what it looks like:

btw, i see some guy has a proxy to overlay the os maps on google earth - so maybe some flex in the terms.

Re: uk ordnance survey maps
 

That looks ever so pretty.
Did you mean http://wheresthepath.googlepages.com/
The full-screen OS map complains about vector mapping not supported but otherwise seems to work fine.

Re: uk ordnance survey maps
 

actually, i was thinking of this one:
http://www.brock-family.org/gavin/go...th/osmaps.html

however i see that multimap is now using mercator projection for its os maps
so a new url format for mm should do the trick. mm only supplies the os topo
maps - higher maps are normal teleatlas version.

Re: uk ordnance survey maps
 

Thanks for that. Yes, I misread 'earth' as 'maps'.
