All the articles with the tag "photogrammetry".
Photogrammetry is just measuring reality with light. Learn how satellites see beyond visible light and convert raw digital numbers into meaningful measurements of our planet.
A camera takes a 3D world and squishes it onto a flat sensor. Learn the math needed to perfectly reverse this squishing and create accurate maps.
Just like your two eyes, two pictures from slightly different spots let us calculate the height of everything in the image. Learn how parallax reveals the third dimension.
Every photon of light has a story, but the atmosphere tries to change it. Learn how to un-do the effects of clouds, dust, and haze to get the true measurement.
On a raw image, tall objects lean away from the center. Orthorectification uses our 3D model to stand everything up perfectly flat, like a flawless map.
Why manually draw roads when you can train a brilliant computer algorithm to do it in milliseconds for the entire planet? Learn how AI revolutionizes map-making.
