Astro-photogrammetry and 3d Reconstruction

~60 min · 15 stations

Astro-photogrammetry and 3d Reconstruction is a self-paced learning path in Astronomy & Space Exploration, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to define the basic principles of spatial data collection in space; identify the role of light in capturing geometric data; explain how lenses distort or clarify spatial input.
