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 ...
