Field Notes from 3/29/21

-

  • Place GCP’s in sequence and be sure there is enough space between each to not weigh data and not to spread them out too much to create under coverage
  • When turning on the Mavic 2 Pro, ensure it is placed on the landing pad before starting to ensure accuracy at zero altitude and reduce the risk of damage to the drone, other equipment, and yourself
  • Ensure clear the area is being called out when about to take off and acknowledge when other crews are doing so
  • DO NOT turn on the transmitter before the aircraft; HUGE safety risk that should never take place
  • Ensure that propellers are being removed before completely placing the drone into the case
  • There is not a step in the checklist to ensure that it is happening
  • Make sure the SD card is formatted correctly and cleared before every flight
  • Ensure PPK is formatted before flights in the DJI M210
  • Do not keep the sensor unattended without the lens cap and DO NOT point it to the sun, otherwise, the sensor will be fried
  • M210 batteries have an extra wire that should be velcro strapped down to ensure that it is not sheared by the propellers during flights
  • Hold session button to turn off when finished with PPK
  • Use married batteries to ensure cycles are synced
  • PPK is different from RTK in that it does positioning after data is collected and goes through the process afterwards
  • Uses GNSS logs to calculate accurate positioning information
  • For tree line assignment, use SRT file format for the video
  • Turn on video captions to display metadata
  • Notes will be used for reference to ensure that everyone is knowledgeable on flying missions

Installing and Using Measure Ground Control

-
Image
  Introduction During the transition of UAVs from a hobby to an actual profession and commercial use, there has been an apparent need for integration within the National Air Space (NAS) and how it fits within the professional world. Mission planning has become an apparent need within the different applications of UAS. Measure Ground Control (MGC) is a mission planning software that integrates flight plans, NAS map, and the ability to fly freely with DJI drones.  Methods To better explore the functionality of MGC, this lab explored the different features that it has to offer. For the flight planning aspect of Measure, the NAS map feature was explored first. Figure 1 shows the map opened and what is first seen initially.  Figure 1 shows the NAS map; the caution symbol is to inform that location of the user was within the Class D airspace of KLAF. As mentioned, the caution symbol is to inform the user that they are within a restricted airspace and that approval is needed to ...

Volumetric Analysis

-
Image
  Introduction Building upon the map fundamentals learned from the lab demo before, the data from the Wolf Paving Piles are used once again for volumetric analysis, but data from the Litchfield Paving Piles area was also used for volumetric analysis and for other data processing. Volumetric analysis is a form of chemical analysis which measures the volume a substance occupies, which in the context of this lab it will be used to measure the volume of the paving piles. ArcGIS Pro has a series of tools and functions that were used to complete this lab demo, which will be discussed in detail later in this post. Methods To perform volumetric analysis, the Extract by Mask tool was used on three separate paving piles. The tool essential outlines a certain section of a raster and masks it as its own raster. A polygon must be created before running this function, to define the area that is being extracted. The surface volume function is then used to directly calculate the volume of the pile...

Week 13 Deliverables

Image
  As the construction went on and the burn plot was finished, this field outing was used to create a 3D model of the construction trailers, and vehicles, while collecting data to show differences in the south burn plot. Similar to the field outing in the prior week, the flight took place at PWA over the construction, south burn plot, and the salamander tanks. The data will be used for comparison in a later field outing, similarly to the first field outing. The metadata is posted below from the flight that was performed.
