tance?: Sensor altitude, sensor width, image width, focal length
3. Can you compare the relative and absolute accuracy of geospatial data used
in RPAS operations?: Relative accuracy is the consistency of spatial relations in
images and absolute is the accuracy relative to known ground coordinates
4. What do "camera depression angle" and "azimuth" mean in the context of
RPAS operations?: Depression angle is the angle from the sensor to the ground
and azimuth is the angle on the horizontal plane, or left and right
5. What is the difference between a low oblique and a high oblique aerial
image?: A low oblique aerial image is one where the horizon is not visible, as the
camera is almost directly below, and high oblique images are at a high depression
angle, looking at the horizon

lap is the last pass of that same area of operations, off to the side.
10. What is the generic workflow used to plan and execute an RPAS mission?-
: Develop a preliminary plan, visit the worksite and gather in situ data, and then
conduct a safety review of the hazards and issues identified during the first two
steps.
11. Differentiate between "area of interest" and "area of operation" regarding
1/7
, RPAS mission planning.: The area of interest is the specific targets that the RPAS

as to where the AV will operate
