OI² - A CLOSELY MONITORED VOLCANO

V - The Database

Pre-treatment :

   As soon as a radar image is received, either via physical hardware (exabyte, CD or DVD) or through downloading an ftp file, it is pre-treated. The pre-treatment has two aims: either to extract part of the image for a preview (quicklook), or to take out the information which is potentially useful for further treatment. This pre-treatment is largely automised, and consists principally of decoding the different formats used by different Space Agencies for their images.

VOLInSAR

   The information extracted is then stored on the MySQL database : VOLInSAR. This database currently stores all the radar images from various projects (OI2 and others). All interferograms calculated are also stored in the VOLInSAR database with their different characteristics.

CASOAR :

   CASOAR is a web interface developped in order to allow the VOLInSAR data to be consulted. A fuller description of this interface is available on the Help page for CASOAR.
