that each photograph needs to overlap the previous photograph by 70% to ensure successful model production. Also assume this feature can be characterized by a single row of photos. For a feature length of 100 m (or whatever length of interest you put in Part 1): Number of photos (d = 10):_____ Number of photos (d = 25):_____ Number of photos (d = 50):_____ Unit 1 SfM Rubric - Introduction to SfM for a geology field program This rubric covers the material handed in for Unit 1 student exercise and is the summative assessment for the unit. Component Exemplary Basic Nonperformance General Considerations Exemplary work will not just answer all components of the given question but also answer correctly, completely, and thoughtfully. Attention to detail, as well as answers that are logical and make sense, is an important piece of this. Basic work may answer all components of the given question, but answers are incorrect, ill-considered, or difficult to interpret given the context of the question. Basic work may also be missing components of a given question. Nonperformance occurs when students are missing large portions of the assignment, or when the answers simply do not make sense and are incorrect. Part A: Workflow (7 points) 7 points: Workflow as a whole is detailed and makes sense; someone who has not used SfM could follow along. Includes the filled-in (and correct) equipment sheet, sketches of a setup in the field explaining camera locations / collection path and target and 3–6 points: Characteristics of an response but missing 1–2 of the pieces listed AND/OR Workflow is not logical and is difficult to follow, but is still usable. 0–3 points: Missing 3–5 of the pieces listed for the workflow AND/OR The workflow is unusable.
GPS location, a list of required metadata, operational procedures, and general steps for data visualization. Part B: Why SfM? (4 points) 4 points: Detailed and thoughtful answer about why to use SfM for research; includes examples and a discussion of the importance (3 points); Research objective of the project/why use SfM for this objective (1 point) 2–3 points: 1–2 of the three listed for an exemplary example; judge based on the number of points assigned to each factor. 0–1 point: 0–1 of the factors listed for an exemplary example. Part C: Data Summary (4 points) 4 points: Includes a list of data collected, including number of photos, platform(s), justification of platform choice, filenames, photos included in the model, collection path map, and photo overlap map with explanation of survey success. 2–3 points: Missing details of the survey (3–4 of the six listed characteristics) AND/OR lack of detail in student response in 2–3 so they are unusable answers. 0–1 point: Includes only 1–2 complete and detailed characteristics listed for an exemplary answer. Part D: Data Exploration and Analysis (4 points) 4 points: Identifies occluded portions of the survey, and the difference between the measurements done by hand or done on the model. Also, all calculations must be correct (3 points); Reflective and complete answer about what surprised them about working with SfM (1 point) 2–3 points: Includes all of the characteristics listed for an exemplary answer but I listed characteristic is incorrect or missing (1–2 points); Answers question about positive and negative aspects of working with SfM, but answer is not thoughtful or reflective (0.5 points) 0–1 point: One listed characteristic that is correct; all listed characteristics but none were calculated correctly (0–1 point); Does not answer reflective question (0 points)
