Hi all,

I want to simulate my gpsdenied environment, and for that I want to spawn the drone at a specific lat/lon inside QGC and GZ world with the same terrain. I am able to change the drone coordinates in QGC, but I would like to spawn it in the same lat/lon in Gazebo around the same terrain, and simulate it flying over the terrain with a downward facing camera comparing the fees with georeferenced satellite images for Localization
