[G04-11] Using drone videos and 3D models for local environment studies
Keywords:Drone, Materials, 3D Model, night-time high school
Introduction
As an earth and environmental science teacher, I consider space and time to be important concepts for students to intuitively understand. Unfortunately, since I teach classes at a night-time high school, it is difficult for students to do field observations during class to see these concepts for themselves.
To make up for this, I tried recording some videos using a drone to give students a better understanding of the space around them. These videos make such difficult concepts as geography, geology and vegetation, easier to understand for students, linking local features.
Drone and Software
I used the Parrot ANAFI series drone and the Pix4DCapture software to record videos of the surrounding areas, using both normal and thermal vision. I also used the Pix4DMapper software to create 3D models of the land.
Examples of Materials
1. Hiki-iwagun Rocks (Tanabe, Wakayama): The sandstone in this area has been eroded, resulting in rock formations that resemble a line of toads. Secondary forests have developed between these rock formations. The trees were historically used for firewood and charcoal, but they are now left uncut, gradually covering the rock formations.
2. Amadori Small Fold (Susami, Wakayama): Situated near the renowned Phoenix Fold, this site is easily accessible from Route 42. The fold's cross-section can be observed from both sides, providing a clear understanding of its continuity. The coastal location, characterized by strong waves, also allows for the observation of wave-induced rock erosion.
3. Koibito-misaki Point, Oka-no-Kuroshima Island, and Oki-no-Kuroshima Island (Susami, Wakayama): A gravel bar extends from Koibito-misaki Point towards Oka-no-Kuroshima Island. We can observe the process of tombolo formation. Additionally, the waves passing around two islands collide on the landward side of Oka-no-Kuroshima Island, demonstrating wave diffraction.
4. Tonda-no-Sentakuiwa Rock (Shirahama, Wakayama): This area features alternating layers of sandstone and mudstone, creating a washboard-like terrain. Although smaller than famous Oni-no-Sentakuiwa Rock, it is an example of washboard rocks in a local site.
5. Meandering of the Otagawa River (Nachikatsuura, Wakayama): The meandering river is surrounded by rice fields, indicating relationship between the river and the adjacent backswamp. Oxbow hills near the river show the dynamic changes in river course over time.
Next Time
To make up for this, it is necessary to listen to student feedback. I wish to use this feedback to make more visual and intuitive materials.
