Using Google Maps images to generate a navigation map/occupancy grid?

Hi,

I was wondering if there are any tools for using images from Google Maps to generate an occupancy grid for navigating outdoors. Specifically:

  1. Is there a software that can directly map lines that I draw on Google Map images to obstacles? For instance, if I manually mark the edge of a building that I see on Google Maps, I want that to show up as an obstacle (black line) on the occupancy map.
  2. How is the scale of the map supposed to be? How do I translate from pixels to meters?

PS - I have been using Gimp to make small changes to maps built.

Thank you.

about your second question, do you mean the MapMetaData/resolution of the Occupancy grid, there you can say how much meter 1 pixel is. http://docs.ros.org/api/nav_msgs/html... I think 5cm/pixel is the default setting.

Thanks! That answers my second question. Any ideas on the first?
