Comparing Images from Drones with Satellite Images
Explore the basic concepts of remote sensing by comparing data collected by instruments on polar orbiting satellites with pictures and videos collected via cameras on recreational drones.

- Satellite image of your location
- UAV with camera
- Ask students to make a hypothesis about this data comparison, for example:
- "The satellite image will cover a greater area than our drone" (YES, of course, but you get the idea)
- Help students acquire a satellite image on the same day they plan to fly their drone. Have them identify as many features as possible (clouds, bodies of water, vegetation types, cities or towns etc…)
- Have students conduct a drone flight and collect camera pictures. Tell them to identify as many features as possible.
- Have students organize their data in a table similar to the one shown below:
|Date||Satellite Image||UAV Photo|
|Data Source & time
- Ask students to state a conclusion based on their data.
- Have students brainstorm additional projects they can do comparing drone data with satellite images, for example: green-up or green-down, identifying ice on nearby lakes, investigating fall foliage, etc…
- Tell students to compile flight log, hypothesis, images, data chart, conclusion and any additional project pictures and results into a short report (or PowerPoint) for a classroom presentation or science fair exhibit.
