Over
the past years airborne laser-scanning has become the primary choice
for gathering precise and dense digital elevation models (DEM) of large
areas for a wide range of applications. It is presently the most
efficient method for DEM acquisition, but it is far from being mature.
Its reliability is confronted with erroneous data distracting potential
customers. This paper intents to describe sources of the errors and to
outline how they can be avoided, corrected and compensated. |

In
this approach the automatic extraction of information is based on the
combined analysis of lidar-and GIS-data. The remote sensing system used
consists of a lidar scanner and a RGB/NIR digital line camera.The paper
will focus on the automatic delineation of the tree crown shapes, the
automatic recognition of forest stand units and the calculation of the
mean tree height of the highest trees in each stand unit and the
calculation of the crown cover density in each unit. |

The
determination of forest and landscape inventory parameters out of
terrestrial laser scanning data is reported and jugded. Possible
applications as well as the gains in information are discussed. |

Proceedings
of the XIXth International Symposium CIPA 2003 "New Perspectives To
Save Cultural Heritage", Antalya, Turkey, 30.09.-04.10.2003, pp. 484-489
Design and applications of the Z+F IMAGER 5003 and the DLR panoramic
camera are reported. The paper focuses on accuracy of the system and
reports the realised approach from physical measurement of point clouds
to coloured point clouds in the end. It shows results from two cultural
landscape conservation projects, one inside and one outside
measurement. |
