    99 * examining profiles over the overlapping regions: allows measurements of the height difference to be made (in Terrascan/Microstation)
    1010 * Re-order points in Terrascan: reorder 'by elevation (Z)' and colour by flightline. This will ideally show a mix of colours in the overlap region. If only one solid colour is shown then this flightline is consistently higher than the the other.
