Identification and analysis of point scatterers in time series InSAR

In this study methods are developed for improved analysis and processing of PSI data. PSI, or radar interferometry, makes it possible to use satellite radar images to measure deformation of the Earth’s surface and objects on it with millimetre accuracy. However, interpretation of the measurements and identifying the actually measured objects is...

Measuring Surface Deformation Caused by Permafrost Thawing Using Radar Interferometry, Case Study: Zackenberg, NE Greenland

Permafrost in high-arctic regions has been very much influenced by global warming. Many thousands of square kilometers of permafrost are under certain degree of thawing. Site measurements have provided useful data for researchers. However, these ground-based measurements are usually site-specific with poor spatial coverage. Here we apply Multi...

Superbus Positioning System: A High Accuracy Networked RTK GPS System

In this report a high accuracy positioning system is investigated for use in the Superbus. The Superbus project is an effort to apply a new and complete conceptual approach to public transport. It consists of a vehicle, logistics and infrastructure. The positioning system for the vehicle is to have a horizontal position error, which will not...

Automatic detection of buried channel deposits using high resolution laser altimetry data (FLI-MAP)

The formation of the current Rhine-Meuse delta has mainly taken place during the Holocene (the last 12,000 years). This period is characterised by avulsions that lead to sudden shifts in the location of river channels. The channel deposits left behind by abandoned rivers are often distinct sandy layers in the shallow sub-surface, called buried...
