Preparation of initial data

After allcompletion of the field workworks, has been done, before proceedingprior to RAW data processing, it is necessary to structure allorganize the dataachieved obtained, for this purpose:dataset:

1. Download all the data to your computer. Photos from the camera and  GNSS files from the GNSSPPK receivermodule of the aircraft; Data from the TOPODRONE laser scanner;LiDAR;
   *.pcap – laser scannerLiDAR sensor file
   *.imr –file from the laserLiDAR scanner'sIMU inertial(Inertial sensorMeasurement Unit)
   *.ubx – raw measurement file from the laserPPK scannerUpgrade GNSSkit or built-in LiDAR PPK (GNSS) receiver
   log.txt – logsLiDAR fromsystem thelog laserdata, scanner, they do notdoesn't take part in processing,processing stage, but they are necessary for diagnostics.diagnostics
   *.raw – fileLiDAR forsystem laserdiagnostics scanner diagnostics,data, not included in processing

   Data set of a single activationSample of the TOPODRONE laserLiDAR scanner.single dataset.

   *.ubx/.obs/.22O/etc. - Static observation files from the base station;
   *.txt/.csv/etc. - Catalog of control point coordinates.
   
2. Distribute eachthe data type to a separate folderdirectories with an appropriate name.names. If you have had multiple flights and/or passes, each datadataset set shouldshall be placedcopied into a separate folder.folder, accrodingly.
3. AllImages photosdataset areshall placedbe inseparated foldersaccording onto separatethe flights, inas well as 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, suchfor asexample Base."Base".
