What sort of questions might a drone help answer?

Columbia Dam Volunteer Drone Team

Are our trees growing? Are the banks holding up? Is the channel staying put? Where is sediment collecting?

Understanding the needs of the “client”

Columbia Dam Volunteer Drone Team

What does the client need to see, learn or be able to explain to others.

Using Drones for Quantitative Analysis: Columbia Dam Removal

Columbia Dam Volunteer Drone Team

The team wants to watch the changes during the dam removal.

• We documented the “pre” conditions

• Documented stages of lowering

• Going beyond just the pictures

Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points.

Columbia Dam Volunteer Drone Team

Photogrammetry allows us to map changes at intervals during the project.

Quantitative Analysis

Ground Point Controls

Several ground control point coordinates are used to calculate the coordinates. In the field, ground control points are marked in a way that makes them visible later on aerial photographs.
