Abstract
This clinic will be a hands-on exercise in making quantitative 3D digital models and orthomosaics from a collection of photographs, focusing on small to medium landscape scenes (think beach ripples to a small dune system). We will provide some background theory and work through the steps of constructing and assessing the accuracy of the model using commercial software (Agisoft Metashape). Pitfalls and best practices will be explained. Students are invited to bring their own imagery (check with us for guidance on best practices for image collection) or we will provide some, and we might collect some prior to the classroom portion. Any laptop will work, but those with NVIDIA graphics cards will be faster.
