hi, all,

I'm writing some planner plugin, and find something confusing.

in navigation costmap, the map array data is organized by column, and we can know that data of X positive axis is point to right, Y positive axis is point to down.

but it is strange in stage simulator or rviz map, it is not like above, the map element data in rviz shows that the X positive axis is point to right, Y positive axis is point to up.

so why this happen? am i missing something?

Please feel free to rectify me. thanks!
