Despite the increasing availability of high quality optical satellite images, continuous monitoring of Earth’s surface changes is still of limited use due to technical limitations. To overcome these limitations, we have developed a processing chain to accurately orthorectify and co-register sets of pushbroom images with accuracy on the order of 1/20 of the pixel size. Combined with a precise correlation technique, this processing chain allows for accurate measurement of ground deformation. Applications related to earthquake ground deformation, ice flow, landslides, and sand dune migration are presented.

The second Practical Semantic Astronomy Workshop took place last week at the University of Glasgow. The workshop brought together experts from a broad range of disciplines using semantic technologies, alongside practitioners experimenting with these technologies to address current problems in astroinformatics. The workshop’s aims were to:
* inform how semantic technologies are being used successfully in other sciences
* reveal what semantic activities are emerging in astronomy
* foster greater communication between groups working in this exciting area
For further information about the workshop and semantic astronomy, see the website at http://www.dcs.gla.ac.uk/workshops/semast09/
