1. 1. Comparing radar satellites. Use of Sentinel-1 leads to an increase in oil spill alerts in Norwegian waters

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Ove Njøten; [2021]
   Nyckelord :Geography; GIS; Satellite; Radar; Oil spill; Earth and Environmental Sciences;

   Sammanfattning : Radar’s ability to detect oil spills through clouds, fog, and darkness is a significant advantage. Oil spill alert services using radar satellites have been in use in Norway for more than 25 years. After introducing two radar satellites Sentinel-1A and 1B in 2015-2016, the number of oil spill alerts has increased by 250% in Norwegian waters. LÄS MER

3. 2. Paleoglaciological study of the Ahlmannryggen, Borgmassivet and Kirwanveggen nunatak ranges, Dronning Maud Land, East Antarctica, using WorldView imagery

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Elena Serra; [2017]
   Nyckelord :;

   Sammanfattning : Paleoglaciological reconstructions based on glacial geological and geomorphological evidence areused to constrain and test numerical models of ice sheet extent and dynamics. The MAGIC-DMLresearch project (“Mapping, Measuring and Modelling Antarctic Geomorphology and Ice Change, inDronning Maud Land”) is trying to reconstruct the timing and pattern of ice surface elevation changessince the mid-Pliocene across western Dronning Maud Land, East Antarctica.

5. 4. Mapping wetland areas on forested landsacpes using Radarasat-2 and Landsat-5 TM data

   Master-uppsats, SLU/Dept. of Forest Resource Management

   Författare :Jennifer Martin; [2012]
   Nyckelord :Radarsat; Landsat; wetlands; classification; land cover; multi-soruce data; remote sensing; Random Forests; Maximum Likelihood Classifier;

   Sammanfattning : Wetlands are an important ecosystem for many vital functions such as groundwater recharge, flood control, water quality improvement, and to mitigate erosion. Monitoring and mapping wetlands on a large scale is becoming increasingly more important, and satellite remote sensing provides a practical approach. LÄS MER

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

   Master-uppsats, KTH/Geodesi och geoinformatik

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

   Sammanfattning : 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. LÄS MER
