Marteloskop vs HeightCzech

With the Marteloskop app you can mark a predefined exercise in the forest. To be able to use this app the supervisor of the exercise needs to create an exercise and share a QR code. Using the app you can scan the QR code and perform the exercise. Once you completed the exercise you can submit it back to the supervisor who will then analyze your results.

HeightCzech is a simple mobile tool for measuring tree height using your smartphone. The application uses the phone camera together with internal motion sensors (gyroscope and accelerometer) to estimate the height of a tree from a known distance. The measurement can be performed directly in the field without the need for additional forestry instruments. The app is designed for foresters, students, researchers and anyone interested in practical forest measurements. Main features: • Measure tree height using the smartphone camera • Simple aiming at the base and top of the tree • Height calculation using phone sensors • Clear and fast interface suitable for field work • Works offline without internet connection HeightCzech demonstrates how modern smartphones can support traditional forestry measurements in a simple and accessible way.
