Lab4-Using ArcGIS Pro to Generate an Orthomosaic with UAS Imagery

Introduction What is the Ortho Mapping Suite in ArcPro? How does it relate to UAS imagery? This program and its tools focus on aerial photography and allow for a series of orthorectified images and maps. What is Bundle Block Adjustment? Bundle block is important because it performs a series of adjustments to each image so that the exterior orientation of the image is changed in a way that matches up with the surrounding images in a more appealing way. After this, the entire image is also adjusted to better fit the basemap. What is the advantage of using this method? Is it perfect? This method provides a cleaner final product but is not perfect. It requires a long processing time and can lead to residual and overall errors. These errors stem from images that were very off focus and the program can not adjust fully but are identified for the user so that they can manually be adjusted. Methods For this lab, we created an orthomosaic using ArcPro. We took a ...

AT 419 Assignment 1: How to Write A White Paper

As the new semester brings in AT 419, a UAS capstone course, we start the semester off with a written assignment designed to introduce us, undergraduate students, to the world of research writing. This style of paper is known as a white paper, and researching and presenting information on these kinds of papers is the focus of this paper. A senior design class, or capstone project, is a project designed by students and allows them to perform research on a topic of their interest. Because these classes are researched-based, it makes sense to produce a white paper in order to effectively present your findings. Since most undergraduate students have little to no experience writing this kind of paper, we are using this assignment to expand our knowledge. In this paper, I will be outlining the purpose of a white paper and how it should be written, along with the differences between a white paper and peer-reviewed paper, the pros and cons of a white paper, and a critique of 3 publis...

Lab 5-Construction of a point cloud data set, true orthomosaic, and digital surface model using Pix4D software

Introduction: What is Pix4D? It is a photogrammetry software that can be used to generate point cloud structures and drone maps. What Products does it generate? Digital surface models, orthomosaics, and point cloud structures. Why is a so integral to UAS data processing, This is integral to uas data processing because allows for quick and easy processing of the data and generation of maps. Methods: For this lab we used Pix4D, a software designed to generate an array of products from aerial imagery, to process the flight data that was given to us from our professor. This flight took place over a house, and we began the process by starting a new project within the software. We updated the camera settings as per our instructors request, and let Pix4D process the images. There were no GCPs used for this flight, so after the initial processing we confirmed the settings and began processing the orthomosaic. We also had the software create a DSM ...
