Detecting clouds in satellite imagery is becoming more important with increasing data availability, however many earth observation sensors are not designed for this task. In Satellite pour l’Observation de la Terre 5 (SPOT5) High Resolution Geometrical (HRG) imagery, the reflectance properties of clouds are very similar to common features on the earth’s surface, in the four available bands (gre...

Tree cover maps are used for many purposes, such as vegetation mapping, habitat connectivity and fragmentation studies. Small remnant patches of native vegetation are recognised as ecologically important, yet they are underestimated in remote sensing products derived from Landsat. High spatial resolution sensors are capable of mapping small patches of trees, but their use in large-area mapping ...

In the framework of the on-going SLAM project (Service for Landslide Monitoring), funded by the European Space Agency (ESA) the Permanent Scatterers processing and the analysis of high resolution images (e.g. SPOT5) have been performed at a basin scale, on the whole territory of the Arno River basin (Central Italy). The project aims at the development of a service based on the integration of EO...

Water scarcity is one of the main factors limiting agricultural development in semi-arid areas. Remote sensing has long been used as an input for crop water balance monitoring. The increasing availability of high resolution high repetitivity remote sensing (forthcoming Sentinel-2 mission) offers an unprecedented opportunity to improve this monitoring. In this study, regional crop water consumpt...

Zusammenfassung: EU-weit ist eine einheitliche Informationsbasis als Grundlage zum Management ungenutzter urbaner Flächen notwendig, um die Ausbreitung urbaner Flächen und die damit einhergehende Zersiedelung der Landschaft in Grenzen zu halten. Das Projekt URBIS stellt ein webgestütztes Informationssystem zur Identifizierung, Charakterisierung, Bewertung und Bekanntgabe dieser Flächen unter Ve...

Here we investigate the potential use of ALOS PALSAR L-band dual and quad polarization SAR data for improved forest structure mapping and parameter estimation. Several scenes of level 1.1 SLC data have been acquired under the DRAGON project in 2007 for the Tai-An test site of Shandong Province, P.R. China. The preliminary results for the first phase of this project are reported here. Firstly, t...
