ACCESS TO DATA
Access to data FROM ERS, Envisat, JERS, ALOS PALSAR
CLICK HERE
The following paragraphs describe some ways to get data from ERS, Envisat, JERS, Radarsat, and ALOS PALSAR data. We need someone to write information about the other satellite systems.
To make a general comprehensive search for data (particularly from ERS and Envisat), we recommend the EOLISA program from the European Space Agency which will run on Mac, Windows or LINUX. If you would like to get information on the Perpendicular Baseline between different image pairs, the best available resource is ESA's DESCW program which only runs on Windows. You can supposedly get Baseline information on EOLISA, but I've never gotten this to work 100% of the time.
To gain access for ERS and Envisat ASAR data (either image or wide swath modes), you can write a ESA Cat-1 proposal to ESA for access to data at reduced cost (about 25 Euros per scene). You need to describe your scientific objectives, how much data you need and of what type and ESA will review your proposal and give you an answer within a few months. This data policy is going to change in 2010.
If you need ERS or Envisat data over regions in North America and are at a research institution, you may be eligible to get data for no cost through one of the following mechanisms.
For selected spots in the world, data from a variety of sources (including SAR, GPS, etc.) have been made available at no cost for the purpose of better understanding hazards. These spots are called supersites, and include major volcanoes (Hawaii, Mt. Etna), areas where recent earthquakes have occurred (for example, Haiti), and areas where future earthquakes will occur (for example, Tokyo, Los Angeles, Vancouver). Some data is available on the supersites for immediate download, while others requires you to obtain a password. Friday, March 11, 2011
