TerraClear Rock Mapping

What is the TerraClear Rock Map?


TerraClear flies your fields with a drone to gather high-resolution imagery. The images are then examined using artificial intelligence to pinpoint the location and the size of the rocks in your field that are 8" and larger. The digital map format (on a tablet or phone) allows you to travel through your fields efficiently from rock to rock. Time spent picking rock is significantly decreased when utilizing the TerraClear Rock Picker. The window for picking rock is increased with a Rock Map because you know the exact location of the rocks in your field. Learn more about TerraClear’s rock mapping and end-to-end solution here.
