Hello All,

Roadmap-1.1.0i has been released here at the garage. It features download of vector maps from openstreetmap.org. So now maps are available for more than the U.S. The GUI tool allows download by lat/lon or GPS position and can take a bounding box or location/radius as parameters.
You can still use tiger maps also. But roadmap-1.1.0i now supports the 1.1.0+ mapset here. So if you're upgrading either-
1.(Recommended) delete all your old 1.1.0 tiger maps and download the 1.1.0+ versions of the usdir.rdm.tar.gz and bndSB.tar.gz files, plus whatever state maps you need. DO NOT USE ANY basemaps PACKAGE FROM THE GARAGE. (They are version 1.1.0.)
2. Keep all your old maps. They still work, but should not be mixed with 1.1.0+ maps.

The idea is one or the other, not both. Also to download maps, wget is required. So if you run into issues, verify it's installed first.

That in mind. Try it out. Report any bugs you find at the garage.

OK, I installed the app. Then I used wget to obtain the map file for one state. Now I'm stuck. I'm sure it's a Linux newbie thing.

First off, where do you figure wget put the file?

Next, what do I do with it? Do I have to "untar" it or something? I have to admit, I could use a step-by-step.

Thanks!

No it's not a Linux thing it's a Roadmap thing...

Roadmap recognizes several map formats.-
- The state by state roadmaps available at the sourceforge page which are based on U.S. Census Bureau Tiger Data.
- Maps downloaded from openstreetmaps.org. These maps are downloaded and compiled using the getmaps_osm program. 'getmaps' in your start menu.

Roadmap will display both maps simultaneously if you have both. So it's best to use one or the ther for a particular area. For example use the tiger maps for one's home state, then download maps on the fly when traveling using getmaps.

If you're using the n810 all you need to do is-
1. create a dir 'roadmaps' on the root directory of either MMC.
2. fire up getmaps point the map location at your 'roadmaps' directory. (I've got 'roadmaps' directories on both MMCs. Roadmap is designed to look on the Internal card for Tiger maps, and on the external card for OSM maps. This allows a way to gps keep things organized.
3. Wait for a GPS fix, press the 'GPS Position' button and then the 'Get OSM Maps' button.
4. Start Roadmap. If you still have a fix from step 2 you can press 'g' and go to your current location.

Hope this helps,

p.s.- To use the state maps download usdir.rdm.tar.gz, bndSB.tar.gz and whatever states you want. Then create a directory on your internal mmc and untar. In xterm this would be-

$ mkdir /media/mmc2/roadmaps
$ cd /media/mmc2/roadmaps
$ tar -xvzf <location of tar.gz file>

How do I download the map ?
I got a fix, pressed 'Get OSM Maps', then the message 'connected' is displayed but nothing is downloaded....
(wget is installed)

thank you.

You are likely downloading the maps. There's no progress indicator on each download. [Getmaps uses 'wget -q -O -' So mapdata goes through stdout. ] But if you want to verify that you are in fact downloading, temporarily change the bits setting higher. (25 maybe). This makes the app download more, smaller maptiles to get the same area. You should see output in the window as each map is compiled. If this doesn't help, run 'getmaps_osm' from xterm, and post back the output.


The 'bits' setting is a little confusing and deserves explanation. It specifies the number of bits in the quadtile address. The more bits, the more tiles. The more tiles the smaller they are. 21 is the default and works for most places. But for dense urban areas you will need to go higher as there is a max size for how much data one quadtile will hold. So trying to download London or tokyo at 21 bits will likely fail.

The flip side of this is that there is slight overlap in the tiles. So the map can look wonky where tiles meet if the bits setting is too high. I generally use-
Big City- 23 to 25 bits
Deserted Wasteland- 19 bits
Everything Else- 21 bits.

hope this helps,

Nope, nothing is downloaded.

location is 50,490,4,210:10km
##bad longitude specified


Thanks !

Edit: its a localisation bug. If I switch from france to US, it works (problem with the decimal separator)

Cool. Thanks for that. It should be an easy fix

Internationalization is the next step. Once I've got the framework into the source, I'll be looking for volunteers to translate the relevant strings. I would ideally like to support as many locales as possible...

How do you create a route in Roadmap? Only loading a previously generated .gpx (outside Roadmap) as a trip?

I have managed to load a map from OSM but now I accept I am lost with this app...

phgerin-

O.K. Should be fixed 1.1.0i-2 is here

try it with your locale and post back.

To anyone on 1.1.0i-1- The only difference is to fix locales where the decimal separator is a comma. (Roadmap uses the comma as a separator between lat/lon. It was getting confused.) Unless this is you, you don't need to upgrade
