    344344Take opposing flight lines.  If there is a pitch error, the lidar will be sensing pulses ahead/behind (along track) the nadir point.  There will be a small overall range error, but the main effect will be that the data is shifted backwards/forwards of where it should be.

    346 Search for areas close to nadir where the height of the surface changes in an clear and predictable fashion, with reasonable sampling density (e.g. a road leading up a hill, or rooftops with their peaks going across-track).

    348348Take along-track profiles on both opposing flightlines.
