Abstract

Advances in laser technology and geospatial accuracy have led to a lasting shift in land surveying methodology. While in traditional field, land was being surveyed by taking orthographic images, todays state of the art involves airborne laser scanners. In a first step, airborne laser scanning only computed and recorded the altitude above ground for each laser echo. Modern scanners, however, are able to record the full wave's spectral information. This is especially useful, as different ground materials exhibit specific laser return signal modifications. However, today it is still very difficult to separate this signal from noise, i.e. trees in forest from watchtowers overgrown with vegetation. To this end, we present a manually annotated data set containing more than 4 million laser return echoes of a characteristic ravine landscape in central Europe. We demonstrate the varying classification achievements obtained by supervised and unsupervised approaches.
