▪
A corridor keeps a very long route's terrain data to a workable size: rather than a full rectangular raster, only a strip either side of the assumed centreline is built.
▪
Give at least three waypoints.
▪
Make "CrossSamples" an odd number, so that one sample falls exactly on the centreline.
▪
Elevation is always downloaded at the maximum resolution available for the area and then interpolated to the requested spacing and sample count.
▪
Opening the Plan/Profile window on a fresh corridor terrain seeds the alignment intersection points from the corridor waypoints automatically.
▪
The corridor plan is drawn unrolled along the alignment, so it runs horizontally whatever the route's true bearing. Use LTCorridorGeographicPlot to see the tiles at their true angle.
