    1212=== Changing display properties ===
    1313From the TerraScan menu select View > Display mode. This is the main dialog for changing how the data looks. EG you can view data by intensity, echo, flight line, class etc. If the display contrast looks odd, select colours and autofit, then apply the changes. Speed should always be normal, unless you want to view the flight directions, in which case select colour by flightline and speed as slow. Zoom functions are on the toolbar on the bottom of the view windows. View windows can be synchronised so that, for example, you can view intensity and elevation at the same points. ''BEWARE the colour scale for viewing by echo, first two colours both mean 1st return (one when only 1 return, one when first of many)''.

     15It may be useful to sort the points into an order other than by time, e.g. by elevation.  Then if you colour by flightline and display slow, it will show the points in increasing (or decreasing) elevation. This can be especially useful for checking for roll and pitch errors due to the affect these effects will have on the elevations.
