Post Acquisition Checks

After data acquisition, it is important to review the collected data to prevent any mishaps, and correct mistakes as early as possible. The idea is to do a quick postprocessing workflow with reduced accuracy/density to ensure everything is in order:

Please follow instructions below after every acquisition. To give some examples, they will save your day when

  • you lose the MicroSD card on the way to the office

  • you didn't safely remove the MicroSD card when downloading data earlier, and are now using a card with a corrupted filesystem

  • rover's storage filled up and you didn't see the warnings on the status LED or in SpatialExplorer

  • you forgot to remove the lens cap on the camera and didn't observe the realtime photo stream in SpatialExplorer

  • a camera stored photos to a memory card that filled up during acquisition and you didn't see the warnings on the status LED or in SpatialExplorer

  • you misconfigured the trigger interval of the camera

  • you forgot to remove the LiDAR sensor cap and don't observe the realtime stream in SpatialExplorer

  • you copied the wrong folder (from a previous acquisition) off of rover's storage and then deleted all folders in the source

  • a reference station didn't log raw observations, or logged observations with no measurements because it's antenna was disconnected, or had no memory card installed, or ran out of power

  • you loaded the wrong flightplan and flew one area twice, and didn't cover the other one at all

  • you mistakenly created a flightplan with incorrect altitude, or flew too fast

  • you accidentally constrained the LiDAR's field of view, but your altitude and flightline spacing requires a larger FOV

  • you selected the wrong measurement program for your Riegl LiDAR, resulting in reduced range or reduced point density

Quick Workflow

To ensure that acquired data is suitable for processing, perform a simplified processing routine, following the Field Data Check workflow.
