AN ITALIAN RESEARCH PROJECT ON DIRECT PHOTOGRAMMETRY
Photogrammetry test GPS/INS calibration
<
2015/6/1
The goals and the phases of the Project are described, together with the test site and the
several, already performed, ad-hoc flights.
The aim is to favour knowledge exchange and collaboration bet...
Usually, filtering is performed in order to extract a ground surface from laser points obtained with the airborne laser scanner. It
mainly removes the laser points that were measured as trees surfac...
TOPOGRAPHY AND DISPLACEMENT OF POLAR GLACIERS FROM MULTI-TEMPORAL SAR INTERFEROGRAMS: POTENTIALS, ERROR ANALYSIS AND VALIDATION
SAR Interferometer Adjustment Algorithms
<
2015/6/1
For connecting the multi-temporal data sets, a spatio-temporal model is proposed that describes the properties of the
surface and its temporal evolution. Rigorous mathematical modeling of functional ...
Unpaved roads are one of the most relevant causes of erosion process in rural regions. Locating unpaved roads in low-resolution
satellite images is not a trivial task. Although they have the spectra...
MODELLING QUALITATIVE AND QUANTITATIVE UNCERTAINTIES OF OBJECTS EXTRACTED FROM HIGHRESOLUTION MULTI-SPECTRAL IMAGES AND LASER SCANNING DATA
Quality Uncertainty Object Extraction
<
2015/6/1
An object-based approach is applied in land-cover feature extraction from high-resolution multi-spectral images and laser scanning
data in this research. Objects extracted from high-resolution spect...
TOWARDS AUTOMATIC OLIVE TREE EXTRACTION FROM SATELLITE IMAGERY
Extraction Feature Automation Satellite
<
2015/6/1
In this paper an approach towards the automatic olive tree extraction from satellite imagery is presented. Counting olive trees in
specific agriculture areas is crucial for the European Union olive ...
LEAST-SQUARES MATCHING USING ELLIPTICAL AREAS: RESULTS, ACCURACY, ADVANTAGES AND DISADVANTAGES
DTM/DEM quality reliability
<
2015/6/1
The use of a square template in least squares image matching has been established as a well known and tested method. This paper
suggests the use of an elliptical template as alternative to the squar...
LINE VORONOI DIAGRAM BASED INTERPOLATION AND APPLICATION TO DIGITAL TERRAIN MODELLING
triangulation reconstruction technology
<
2015/6/1
Local coordinates based on the Voronoi diagram are used in natural neighbour interpolation to quantify the “neighbourliness” of
data sites. In an earlier paper, we have extended the natural neighbour...

2015/6/1
VLMS is a mobile mapping system, where three single-row laser range scanners, six line CCD cameras as well as a GPS/INS based
navigation unit are mounted on a van, measuring object geometry as well ...
SAR DATA ACQUISITION FOR EVENT-DRIVEN MAPPING OF URBAN AREAS USING GIS
SAR, Building Detection Urban Simulation Fusion
<
2015/6/1
Airborne SAR systems allow a flexible ground mapping with high geometric resolution, independent from daytime and weather
conditions. This offers the opportunity of using this technology for the ana...

2015/6/1
Using airborne laser scanner data, buildings can be detected automatically, and their roof shapes can be reconstructed. The success
rate of building detection and the level of detail of the resultin...
By means of the progress in photogrammetry; it is now possible to produce the maps of huge areas more quickly and economically
but the production steps are still expensive and time consuming. In rec...
For 3D city management visualization, query and the analysis of 3D data related to cities are very important tasks. In this paper, we
