Hi, long time gazebo user. First time poster.

I am creating a sim of a drone flight across a 200 mile corridor. We will be doing some RF simulation and have digital elevation maps of the entire area. We have done this simulation before but only in small local areas. What would be the approach to modeling a world that is 200 miles long? We can load in the entire 200 mile corridor at once (models, terrain data, etc), but the computational and memory overhead will most likely crash gazebo.
