eMotion in-depth guide
Note: eBee RTK has a minimum distance between images that de-
pends on wind strength and direction. The maximum longitudinal
overlap depends on this minimum distance as well as the calculated
altitude and the camera model. If the calculated altitude is too low
the drone may not be able to achieve the required longitudinal over-
lap. This will be indicated by a icon. Flying at an altitude of less
than 40 m is potentially dangerous and will be indicated by a icon.
• Use elevation data to set absolute waypoint altitudes: Checking this
box will enable the flight planner to adjust the absolute altitudes of all mis-
sion waypoints based on elevation data. This advanced planning mode is
described in detail in section ‘3D mission planning using elevation data’ on
page 78.
Default value: disabled
• Lateral overlap: The percentage of overlap between the ground coverage
of pictures from adjacent flight lines. For most mapping purposes, a mini-
mum of 50% is usually required. Higher coverage values may increase the
mapping quality but will increase the flight duration.
Default value: 60 %
• Longitudinal overlap: The percentage of overlap between the ground
coverage of pictures taken consecutively in the same flight line.
Default value: 70 %
• Generate perpendicular flight lines: Checking this box creates a second
pass over the desired area perpendicular to the first pass. This option will
significantly increase the overall image overlap and therefore improve the
resulting map quality in Postflight Terra 3D. It is particularly useful for diffi-
cult terrain at the cost of doubling the required flight time.
Default value: disabled
• Reverse flight direction: By default, the flight planner will design a flight
in which the drone begins a mission at the farthest waypoint and finishes
