Flight lines with sections re-flown

by Technical Evangelist on ‎10-03-2019 11:15 AM (130 Views)

Question

Sometimes a small portion of a flight line needs to be re-flown. For example, if there is cloud shadows or if the sensor missed a frame. When the small section is re-flown, sometimes the flight direction is 180 degrees (opposite from) the original flight direction. What is the correct procedure to handle this? Do I use the strip wizard to enter the entire strip in and then just change the orientation of the re-flown images to correct the flight direction?

Answer

You should treat any re-flights as a new strip name and import/create Strip/Photos/EO separately. The ties should have a control point or extra measurements at strip ends if possible.
