1. 1. Identifying active water flow paths in a tropical wetland with radar remote sensing data (wetland interferometry) : The case of the Cienaga Grande de Santa Marta, Colombia

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Alice Guittard; [2016]
   Keywords : wetland interferometry; InSAR; water flow path; Cienaga Grande de Santa Marta; wetland monitoring; mangrove forest;

   Abstract : Despite being one of the most productive ecosystems on earth, wetland areas have been heavily affected by human activities. The Cienaga Grande de Santa Marta (CGSM) in Colombia is one of these wetlands, where the inadequate construction of roads modified the hydrology and connectivity of this water body, generating massive mangrove mortality episodes.

3. 2. A 2D Electrical Resistivity Survey of Palsas in Tavvavuoma, sub-arctic Sweden

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Per Marklund; [2014]
   Keywords : Palsas; permafrost; peat plateaus; resistivity; ert; geophysics; Tavvavuoma; Palsar; permafrost; torvplatåer; resistivitet; ert; geofysik; Tavvavuoma;

   Abstract : Electrical resistivity tomography (ERT) is a commonly used geophysical method to investigate permafrost in the mountain environment, but few studies have employed this method in a permafrost affected peatland. For this thesis, 5 ERT profiles were measured over 17 palsas and peat-plateaus in a palsa peatland environment in Tavvavuoma, northern Sweden, where the primary aim was to investigate the depth to the base of permafrost under the mounds.

4. 3. Comparison and Fusion of space borne L-, C- and X- Band SAR Images for Damage Identification in the 2008 Sichuan Earthquake

   University essay from KTH/Geodesi och geoinformatik

   Author : SIN WAI LAU; [2011]
   Keywords : Remote sensing; SAR; image fusion; Sichuan earthquake; PALSAR; RADARSAT-1; TerraSAR-X;

   Abstract : Remote sensing has been widely used in disaster management. However, application of optical imageries in damage detection is not always feasible for immediate damage assessment. In the case of the Sichuan earthquake in 2008, the damaged areas were covered by cloud and fog for most of the time. READ MORE

5. 4. Mapping of Floodplains in the Atankwidi River Basin

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Andrej Nikolaev; [2010]
   Keywords : Idrisi; C-band; L-band; Atankwidi; mapping of floodplains; SOBEK; Technology and Engineering;

   Abstract : The Atankwidi River Basin is situated in the Upper East Region of Ghana. The Basin has an area of around 275 km2. The semiarid climate in which the Atankwidi is situated is characterized by one rainy season spanning from April to September and one dry season spanning from September to April. READ MORE

6. 5. Mapping of clear-cuts in Swedish forest using satellite images acquired by the radar sensor ALOS PALSAR

   University essay from SLU/Dept. of Forest Resource Management

   Author : Anders Krantz; [2009]
   Keywords : Remote Sensing; Forest monitoring; Algorithm; change detection; JAXA;

   Abstract : This study presents results for observing forest changes in Sweden using multi-temporal L-band satellite data and is a part of the JAXA’s ALOS Kyoto and Carbon Initiative. An extensive dataset of images acquired by the Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture Radar (ALOS PALSAR) is investigated for clear-cut detection in boreal forests in northern Sweden (Lat.
