Part 1 Cast study link has been uploaded by way of PDF
Part 1 – Case Study. Select one of the four case studies listed in the Module Topic Core Concepts. Try to select a case study with the fewest responses when preparing your post. In your discussion post, summarize your chosen case study in 150-200 words. Then, in 250-300 words (for a total of 500) identify the appropriateness of the airframe, powerplant, sensor package, C3, and any support equipment, and explain whether you agree or disagree with the choice of UAS for the mission. Using the information learned in the previous modules, justify your answer with use of references or examples. List the case study number in the title of your post. This post is due byday 4 of the module week.
Part 2 – Risk Management. Read all your classmates’ discussion posts. Then, choose at least one post and identify one mission-specific hazard, assess the level of risk, propose a mitigation and assess the level of residual risk. Make specific reference to your reading in your post. This post should be 200-300 words. This post
FOR PART 2 Wendell’s Post:
This case study highlights how archaeologists are integrating aerial imaging and photogrammetry software with low-cost multicopters on the market. Off-the-shelf unmanned aerial systems are showing extreme versatility and adaptability to be used anywhere. So versatile that it was used in the exploration 3D modeling of the ancient Maya port site of Conil, that is located in northern Quintana Roo, Mexico. The aim of the aerial surveying conducted in this case study was to obtain an accurate Digital Elevation Model (DEM) of the site that could be compared to a model that was created using a ground total station (Glover 2006) (Meyer, D., Lo, E., Afshari, S., Vaughan, A., Rissolo, D. and Kuester, F. 2019). Using a 3DRobotics Aero-plane, Structure From Motion software (SFM), and a Sony QX1 camera that is attached to the platform is all that it took to create a 3D digital reconstruction of the historic site. In this study the team also used the computer program Agisoft Photoscan Professional to create reconstructions from the aerial imagery that was taken. As a result UAS can provide a better depth and higher resolution than satellite, and they can provide scalable surveying solutions where difficult.
System Used
The 3DRobotics Aero-plane UAS that was used in this archaeological 3D mapping is a fixed-wing single propeller system, partnered with the Sony QX1 camera and the Structure From Motion software (SFM). I disagree with the choice of platform only being that the 3DRobotics Aero-plane cannot hover in place, it has to constantly be on the move making multiple passes to achieve the desired outcome. This can become a problem when the platform has to navigate tall difficult structures or trees. Also, this platform can become susceptible to outside conditions such as high winds. In comparable mission multi-rotor system such as a DJI Mavic 2 in combination with the same technological software will perform better. Multi-rotor aircraft are the most commonly used drone models for making maps and models with DroneDeploy. In fact, they make up 97% of the drones mapping on our platform (DroneDeploy, 2017). On the basis of comparing launching between the two systems, the multi-rotor platform can instantly go into performing the mission as it will operate and any elevation within regulation to perform the mission. The fixed-wing system has to be launched from a ground station or manually thrown in the air, also the system has to elevate to a certain altitude, and make multiple passes before the system is ready to construct a 3D image of the desired site. Multi-rotor platforms have greater maneuverability, lower prices, more compact, easy-of-use, and higher payload capacity than that of the fixed-wing platforms.
This must be ORIGINAL Work NOT Plagiarism I must have this by Tuesday PLEASE.
