Preparation of initial data

After all the field work has been done, before proceeding to processing, it is necessary to structure all the data obtained, for this purpose:

1. Download all the data to your computer. Photos from the camera and files from the GNSS receiver of the aircraft; Data from the TOPODRONE laser scanner;
   *.pcap – laser scanner sensor file
   *.imr –file from the laser scanner's inertial sensor
   *.ubx – raw measurement file from the laser scanner GNSS receiver
   log.txt – logs from the laser scanner, they do not take part in processing, but they are necessary for diagnostics.
   *.raw – file for laser scanner diagnostics, not included in processing

   Data set of a single activation of the TOPODRONE laser scanner.

   Static observation files from the base station;
   Catalog of control point coordinates.
   
2. Distribute each data type to a separate folder with an appropriate name. If you have had multiple flights and/or passes, each data set should be placed in a separate folder.
3. All photos are placed in folders on separate flights, in the same folders put *.ubx files from these flights, which are on a microSD flash card installed in TOPODRONE PPK Upgrade Kit on the aircraft.
   

   Please note that the photos should be separated exactly by flight. In DJI aircraft, photos are named with a numerical designation from 1 to 999 (For example, DJI_0001.jpg and DJI_0999.jpg), if you have more than 1000 files, the system will start writing the images to a new folder named DJI_0001.jpg

4. Be sure to convert the static observation file from the base station to RINEX format and move it to a separate folder, such as Base.
