Measure tree height with your smartphone
HeightCzech is a mobile application designed to measure tree height quickly and accurately using only a smartphone.
It promotes the idea of “no-cost forestry measurement” – transforming an ordinary phone into a precise field instrument.
The app uses built-in IMU, gyroscope, and camera to estimate the vertical angle to the tree top and base.
By combining these measurements, it calculates the total tree height without any external equipment or manual calculation.
HeightCzech is intended for foresters, students, researchers, and anyone interested in understanding forest structure. It can be used in training, forest inventory, or even quick verification of drone or LiDAR data in the field.
Key Features
Direct height measurement using smartphone sensors (no external devices)
Intuitive camera-based interface
Optional data export for integration with GIS or remote sensing projects
Concept and Future
The app continues the philosophy of the iScanForest Apps project — bringing scientific tools to everyone through creativity and software innovation.
Future versions will include options for tree crown analysis, multiple measurements per plot, and cloud synchronization for educational and professional use.
