     8The elevation between neighbouring flight lines must be checked too. There is currently a roll-issue with the lidar data, which in particular needs to be looked for ([wiki:Procedures/lidarprotocol This] page may be helpful). Elevation discrepancies can be found in various ways:
    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.
