Processing image data
If you used a local base station and didn’t have its precise position, you have
an extra post-flight processing step to do. eMotion will calculate the precise ab-
solute position of your base station using the raw logs from your base station
and the raw navigation and observation logs from your reference station. The
precisely-measured position of your eBee RTK relative to your base station will
then be corrected using this calculated absolute base station position to obtain
high-precision absolute geo-tags for your images.
If you used a virtual reference, your Ntrip stream provider will have automati-
cally providedeMotion with precise virtual base station coordinatesor linked eMo-
tion to a fixed reference station. As your eBee RTK was flying, eMotion was sending
RTK corrections, gathered from the Ntrip broadcast, to your drone and your drone
was logging the precise coordinates of each image it took.
If you flew your eBee RTK in standalone mode, you do not have any RTK cor-
rections; all the flight data you need is stored onboard your drone.
Follow these steps to import data from the drone:
• Step 1 - Select a flight: If the flight was monitored from the computer
you are using to import images then the flight is saved within the local
database. Select the date that the flight took place. A list of flights (in-
cluding number of images taken) from that date will appear in the combo
box, select the one you wish to import.
• Step 2 - Create a directory: Choose a directory name that uniquely iden-
tifies your flight (e.g. the date, the name of the area, etc.).
