Some more maps:

Denmark: //http://dl.dropbox.com/u/24093622/denmark.osm.map

Netherlands: //http://dl.dropbox.com/u/24093622/netherlands.osm.map Note: there is a white hole in the map - I am assuming it is some bug in the rendering/OSM data.

Great Britain: //http://dl.dropbox.com/u/24093622/great_britain.osm.map

- only that for me all works fine. Anyone similar experience? Also did this "pick" photo do not work for all photos? For me, it doesn't work for some sync photos from picasa but from photos from camera this works.

I had the same experience when picking a photo, I can select one in Gallery, but there is nothing when I return to Locus.

-peter

My point? None, I just thought it interesting. Nice that the developer thinks Locus is nice, no?

OruxMaps point? I dunno - no point in copying functionality from Locus in OruxMaps - then why not use Locus instead...

I used OruxMaps before I found Locus, or tried to use it - I found the user interface very confusing,

-peter

I saw the Köln problem - but strangely it disappears again when you zoom in more.

I was wondering - did anyone else try to make maps with osmosis/mapsforge?

-peter

Locus has been noticed:

Yes on the macbook.

Could it be that if the memory is not enough, it goes too slow? When I tried Great Britain for the first time, I stopped it after an hour. When I increased memory again, it ran in 1384 seconds. But that machine has 8 intel quadcores and 128 GB of memory.

No problem! Here are some figures. I ran those four on my MacBook Pro (late 2007 model) with 4 GB of RAM. I show the sizes of the osm/map files, the time taken according to osmosis and the unix "time" command, and the memory used, taken from the "top" command.

I ran some bigger maps at work, but that machine is down at the moment. I'll see if I can get those figures later.

It only works with the testing version of Locus Free which you can download from the beginning of this thread.

I was going to try and find time today to try building a map (although I have no experience with Osmosis, which looks like it has a learning curve). Now I am discouraged     Would it work OK if I were to just build a small map, say the southern 1/4 of NH? How long do you think that would take? A small map would be OK for testing Locus.

Not sure... I managed to build the Netherlands map, but I had to allocate 16GB to Java. Then I tried Great Britain, that worked also. Next up was France, but that crashed with a Java out of heap space error, even with 16GB allocated. So I will try later today with more memory; other people are using that machine now.

Osmosis was easy to get going - I downloaded osmosis, downloaded the trove jar (link is on the mapsforge page, and installed the plugin in my home directory. It worked without problems (tried on both my MacBook, and a debian server at work).

Like "Time rings"

Time rings?

Hi,
is it possible to create croatia (Peninsula of Istria would be fine) for testing? I'll go there on friday and haven't found any satisfying map-sources for biking.
OCM seems to be not very useful for offroad-tracks.

I took the croatia.osm.pbf from geofabrik.de and made a map (I didn't test it though, but my sweden map worked): //http://dl.dropbox.com/u/24093622/croatia.osm.map

-peter

Some other observations... would it be possible to enable more than one vector map? I live in the border area between The Netherlands and Germany, and that involves switching maps (unless I make a Europe Vector map )

Is there (a 2 GB) limit on the vectormap size? I saw that Germany is 1.15 GB.

Is there some kind of caching possible? Zooming  in and out seems to redraw from scratch. I realise vectormaps are not tiles, so this is maybe not possible.

O, and a little bug. If I switch vectormaps, the new one won't show until I zoom in our out. (edit: on second look, it seems to work right, but the disabled map still shows until I move away.)

Also, 50m seems to be the max-zoom, but the (+) button does not get disabled.

-peter

It also needs a lot of memory -  I tried doing The Netherlands, but it didn't work with 4 GB.

I am now trying on a debian machine at work, it has 8 quadcores and 128 GB of memory

-peter

Yes, not so difficult. I made a map for sweden, and it looks nice in Locus!

I am putting the map onto my dropbox account, but it takes an hour to upload. I'll put a link when it is ready. And it is: //http://dl.dropbox.com/u/24093622/sweden.osm.map

-peter

Will you be interested in creating any other country? Don't know from where are all of you

Yeah, I would. For both Sweden and The Netherlands I live divided in both )

Is it difficult/time consuming? I already make my own OSM maps for garmin with Osmosis and mkgmap. I assume these kind of maps are not more difficult?
