Ground Truth, or how to resurrect a tree

Exhibitions
Explore the fascinating world of remote sensing technology and its role in understanding forests. The exhibition highlights the project's journey in developing advanced imaging techniques, predictive models, and the interplay between technology and nature. Visitors are encouraged to delve into the concept of "seeing the invisible" through cutting-edge methods and computer-aided vision, revealing a new perspective on the natural world.

Forests are very visible, the technology and techniques used to study them are not. Ground Truth, or How To Resurrect a Tree is a story about ‘seeing something when there is nothing there.’ The project explores the discipline of remote sensing.  

Following the quest of remote sensing researchers to develop a better interpretation model of satellite data, this project explores cutting-edge imaging techniques of forests while looking back at photography’s love affair with natural landscapes. Using meticulous on-site measurements of physical structures and spectral properties of trees, researchers develop reliable predictive models. Ground truth data is often compared to experimental results to verify the performance of a model. A successful model allows us to distinguish various features of the Earth beyond what is shown optically in a satellite image. A computer-aided vision grants us the ability to exceed the resolution limit of the extraterrestrial apparatus, to resurrect a tree from the data collected by satellites. Powered by advanced imaging technologies and algorithms, seeing is more abstract than ever.
