App4SHM vs HeightCzech

App4SHM is a smartphone application for structural health monitoring (SHM) of bridges or other civil structures to assess their condition after a catastrophic event or when required by authorities and stakeholders. The application interrogates the phone’s internal accelerometer to measure structural accelerations and applies artificial intelligence techniques to detect damage in almost real time. App4SHM resulted from academic research developed at Lusófona University, in particular the Civil Research Group and the Department of Computer Engineering and Information Systems.

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.
