Mission Planning Search and Rescue

Image
Introduction The goal of this lab is developing a plan for an operation where a person went missing in Martell Forest and search teams are sent out within an hour. There is an idea where the person is but they could have moved, it is expected that they will be found. The gear that is to be used Bramore PPX, with Altum multispec, or a sony RX1 M600, with Sony A600, Mica Sense Red edge, FLIR XT2 Figure 1. A map of Martel forest Figure 2. The airspace map of the area Methods Initial action The plan for the initial action is to do a hasty search with the Matrice 600, with the FLIR XT2 camera. This is the plan for the hasty search, as the thermal imaging should be able to identify the person quickly as there is a large temperature difference between the person and the forest in November. The use of the M600 would be a hasty search and searching in an outward spiral from where the person is expected to be. This is because there is a rough idea of where the individual could...

Metar TAF and Airmets

Introduction  The use of metars, tafs and airmets are the accepted ways to gather weather information for a commercial operation of a uas. The weather requirements for uas operations under part 107 include, a minimum of 3 statue miles of viability and must be 500 feet below and 2000 feet to the side of the clouds.  Decoding a Metar and Taf Figure 1.

Airspace for UAS operations

Image
Introduction Airspace is one of the most important things when operating a UAS, it becomes even more important when operating under part 107 as you can transition into airspace while flying within 400 feet of a structure, Methods Operations that take place in air space are broken down into a few key parts, the class of airspace being the most important one. The sectional chart legend Figure 1. the sectional charts show the symbols for the airspace, airports, and obstructions. These symbols allow the pilot to understand the sectional charts. Another Chart the FAA put out recently is the Airspace Guidance for Small UAS (Figure 2) which helps operators know how the airspace looks and what authorization is needed. Both of these were used for the sectional chart and airspace analysis of the operation locations, but more information was needed for the areas so other things were used to supplement the briefings. Figure 1. Sectional Chart Legend from the FAA Figure 2, FAA airspace g...

Multi-spectral image indices

Image
Introduction The goal of this lab was to use ArcGIS Pro to view the various band stacks of orthomosaic imagery and a normalized difference vegetation index (NIVD). The data was collected by Dr.Hupy, William Weldon and Zack Miller, and the data was of a controlled burn with multi spectral cameras. Methods The methods of this lab was to look at the areas that were burned and compare them to the areas around them that were not burned. This could be done with RGB, or band stacking for the imagery, which allows the ability to see things that are not able to be seen with the human eye. Results  The data collected with the band stacking shows the differences between the pre burn and post burn data. Figure 1 and Figure 2 show the data in standard RGB, these images are good as a base, and give us a better idea of that we are looking at. In figure 2 take note of the not burned section in the middle burned section as that can be seen more clearly in the other figures. Figure 3. and F...
