Hi all,

I have developed a GUI in Qt4.x that shows the 2d map of environment which is being published by "gmapping" node. Now i want to add in that gui the position of robot which i think can be taken from /odom but when i try to draw it in my gui it shows very little change in pixels. My question is that how gmapping converts the axis coordinates to pixel information in /map. i am using electric on ubuntu 10.04 with Qt4.x Thanks in advance. Regards

MapMetaData, published by gmapping (also included in the OccupancyGrid message), should have everything you need. Specifically, the map resolution in meters/cell, and the map origin.
