| description | Today the use of spaceborne Very High Spatial Resolution (VHSR) optical sensors for automatic 3D information extraction is
increasing in the scientific and civil communities. The 3D Optical Metrology (3DOM) Unit of the Bruno Kessler Foundation (FBK)
in Trento (Italy) has collected stereo VHSR satellite imagery, as well as aerial and terrestrial data over Trento, with the aim to create
a complete data collection with state-of-the-art datasets for investigations on image analysis, automatic digital surface model (DSM)
generation, 2D/3D feature extraction, city modelling and data fusion. The testfield region covers the city of Trento, characterised by
very dense urban (historical centre), residential and industrial areas, and the surrounding hills and steep mountains (approximate
height range 200-2100 m) with cultivations, forests and bare soil.

This paper reports the analysis conducted in FBK on the VHSR spaceborne imagery of Trento testfield for 3D information
extraction. The data include two stereo-pairs acquired by WorldView-2 in August 2010 and by GeoEye-1 in September 2011 in
panchromatic and multispectral mode, together with their original Rational Polynomial Coefficients (RPC), and the position and
description of well distributed ground points. For reference and validation, a DSM from airborne LiDAR acquisition is used. The
paper gives details on the project and the dataset characteristics. The results achieved by 3DOM on DSM extraction from
WorldView-2 and GeoEye-1 stereo-pairs are shown and commented. |
