Synthetic aperture radar interferometry is an imaging technique for measuring the topography of a surface, its changes over time, and other changes in the detailed characteristics of the surface. By exploiting the phase of the coherent radar signal, interferom-etry has transformed radar remote sensing from a largely inter-pretive science to a quantitative(More)
The main limitations of standard nadir-looking radar altimeters have been known for long. They include the lack of coverage (intertrack distance of typically 150 km for the T/P / Jason tandem), and the spatial resolution (typically 2 km for T/P and Jason), expected to be a limiting factor for the determination of mesoscale phenomena in deep ocean. In this(More)

This paper introduces Pluggable Interactive GUI-lets (or Piglets, for short) as a means for constructing reusable, reactive graphical user interfaces that can be instantiated over different view models and presentation layers. Piglets therefore provide an attractive alternative for pragmatic user interface specification that can target multiple content(More)
