1. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping
Sammanfattning : Urban represents one of the most dynamic areas in the global change context. To support rational policies for sustainable urban development, remote sensing technologies such as Synthetic Aperture Radar (SAR) enjoy increasing popularity for collecting up-to-date and reliable information such as urban land cover/land-use.

2. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping
Sammanfattning : Urban land cover mapping represents one of the most important remote sensing applications in the context of rapid global urbanization. In recent years, high resolution spaceborne Polarimetric Synthetic Aperture Radar (PolSAR) has been increasingly used for urban land cover/land-use mapping, since more information could be obtained in multiple polarizations and the collection of such data is less influenced by solar illumination and weather conditions.

3. Urban Land-cover Mapping with High-resolution Spaceborne SAR Data
Sammanfattning : Urban areas around the world are changing constantly and therefore it is necessary to update urban land cover maps regularly. Remote sensing techniques have been used to monitor changes and update land-use/land-cover information in urban areas for decades. Optical imaging systems have received most of the attention in urban studies. LÄS MER
4. Spaceborne SAR in Sea Ice Monitoring: Algorithm Development and Validation for the Baltic Sea
Sammanfattning : The usefulness of new spaceborne synthetic-aperture radar (SAR) sensors at L-, C-, and X-band for operational sea ice monitoring in the Baltic Sea has been evaluated. It is concluded that the information content in C-band and X-band data is largely equivalent, although larger spatial coverage is an advantage of the current C-band satellites. LÄS MER
5. Modelling and Retrieval of Forest Parameters from Synthetic Aperture Radar Data
Sammanfattning : Currently, one of the most uncertain factors in the global carbon cycle models lies in the terrestrialcarbon stock, mainly forests. The available methods for global forest resource mapping provide onlyrough estimates of biomass, the most relevant practical quantity related to carbon stock. LÄS MER
