UAS Sensors and Data Collection

Introduction Measure Ground Control (MGC) is an application in which there is everything from Airspace to flight operations to mission creation and data management. A benefit of Measure over DJI GSP is that one person can create flights and assign them to different pilots.  Methods      Airspace MGC integrates airspace authorization with Airmap a LAANC provider. I checked out a variety of areas to see what the grid altitudes are and other rules and advisories.  Figure 1. MGC Airspace Rules and Advisories for 132 Andrew Place, West Lafayette I checked to see what airspace my apartment was in and there is the class D airspace from LAF, and a school nearby. I am in a LAANC zero grid. I also looked at two of our flying sites, Purdue Wildlife Area and Martell Forrest.  Figure 2. MGC Airspace view of Martell Forrest Figure 3. MGC Airspace view of Purdue Wildlife area Both Martell forest and PWA are outside the KLAF class D airspace, so they are class G airspace, ...

 Introduction Getting to Know ArcGIS Pro, I followed a tutorial on how to develop a map and use features to tie various locations together. Then after learning the basics of ARC Pro, we proceeded to learn how to apply it to UAS data, with DSMs, shaded surface models, and more.  Singapore Tutorial  This is how I went about going through the tutorial.  Figure 1. The project ‘Singapore Tourism’ map has been created. (Note, the data is already imported due to starting the lab with the last sheet) Figure 2. Using the Locate feature in ARC Pro, the map adjusts to Singapore. Figure 3. The data is imported from the datasets downloaded from the Arcgis website. Figure 4. The map's appearance is changed to a gray canvas base map. The icons have been changed to teardrops for the attractions. The train stations were changed to black and gray coloration, and the rail lines were changed to arctic white. Figure 5. A geoprocessing tool called spatial join is used to link each tourist...

 Introduction Pix4D is an application for processing drone imagery and creating various types of orthophotos. The orthophotos can be used to analyze the imagery in a 2d map or a 3d imagery. It can be used with all sorts of sensors and methods of capturing imagery, from a simple DJI Mavic pro to a Sony a6000 with a PPK GPS for positing. In this lab, a few sample datasets were processed to aid in the introduction of this application.  Methods In this lab, data captured on the Purdue Wild Life Area was processed. This data was taken with various aircraft and was all processed in PIX4D. This lab served as an introduction on how to process the different aircraft data as they each have a different set of parameters.  Mavic 2 Pro The Mavic 2 Pro was flown in a grid pattern, and it captured 81 images that were stitched into an orthophoto in Pix4D. The Mavic Pro 2 has a camera with a rolling shutter. Hence, it is important to verify that the automatic camera settings have applied...
