Map not show - osm_cartography

[Gonzalo Tejera]

Hi. I am using osm_cartography to show on rviz a map. 

Steps follows:

1-install osm_cartography package.

2-download a map using the export service in http://www.openstreetmap.org/

3-run roscore

3-run osm_cartography osserver

4-run  osm_cartography viz_osm _map_url:=file://~/map.osm

5-run rviz

6-in rviz add topic visualization_marker_array

But no map is show, rviz only show the grid.

Sure something is missing, any idea?

Regards, Gonzalo

PD: Display panel include a warning message "Global Status: Warn. Fixed Frame No tf data. Actual error: Fixed Frame [map] does not exist"

I am not sure a '~' in the URL will be expanded correctly. You might try replacing it with your actual home directory path.

What fixed frame is selected? 

The current version of these packages has moved to github:

 https://github.com/ros-geographic-info/open_street_map/tree/master/osm_cartography

 http://wiki.ros.org/osm_cartography

Please use that version, report any issues there, and ask questions on answers.ros.org.

Thanks,

It's been a while since I've used this package. Maybe you need to set the rviz fixed frame to something like /map or /map_local. I can't remember exactly.

That is from the correct source, then.

Since I did not find any answer on answers.ros.org or here, and since I had a similar issue, I want to add here a very basic consideration. If you try to open the launch file inside the osm_cartography folder, you'll find a static transform:  <node pkg="tf" type="static_transform_publisher" name="local_map_tf" args="622150 3362350 0 0 0 0 1 map local_map 100" />

this is the transform to the UTM reference frame for the downloaded openstreetmap. If you try do download your own map, you need to create a new transform with the coordinates of your area. For the lat/lon to UTM conversion, you can use this link http://www.rcn.montana.edu/resources/converter.aspx

I think this should be included in the readme of the project :-)

Thanks for the report.

So it does not end up getting lost, would you please open a github issue for this?
