Word of the Week: Photogrammetry


Just because you have a college degree doesn’t mean that your education should be over. Learning new words is fun and can give you that certain je ne sais quoi in everyday conversation.

The clock is broken.

Oh, you mean the …chronograph? 

….oh yes.

Today, we are going to talk about a cool word called photogrammetry, which basically just means using photographs to map physical spaces and measure the distance between objects.

But just knowing its definition isn’t enough. Photogrammetry is actually a quite relevant concept in the world of data, analytics, and visualizations.  Many maps are made through the process of photogrammetry. Photographs taken from satellites and airplanes can be used to create accurate topographical or satellite maps of land masses. The police can also apply photogrammetry by taking detailed photos of a crime scene and later recreate the scene using 3D modeling, even long after the evidence has been cleared away.

Photogrammetry is also applicable within the realm of 3D spatial modeling and data visualization. Every photograph contains innumerous data points pertaining to the shapes of objects, the nature of the terrain, and the distance between the items in the photo. These data points can be visualized using 3D programming to create stunningly realistic digital visualizations.  A policeman can comb the visualization for blood spatter, a pilot can maneuver his route around turbulence-causing mountains, and an automobile company can analyze the results of a collision test by viewing photographs of the deformation of the vehicles.

So, the next time someone asks you if you’re into photography, you can say  “No, I’m into photogrammetry.”



That’s all for now!
