Learn how to use synthetic aperture radar (SAR) data from the Alaska Satellite Facility (ASF). Each Data Recipe gives step-by-step instructions for how to complete a specific task. Some recipes cover basics such as getting an RTC product into a viewable format for GIS, others allow you to terrain correct Sentinel, JERS, ERS, Radarsat or ALOS PALSAR data. For a complete recipe list, please go to www.asf.alaska.edu/data-tools/data-recipes/.

Hi, thanks for sharing this amazing workshop. I have a question though. I don't have the option "insar_analysis", why is that? Can I choose another environment on the list to do the same process?
excellent work. maybe there is a lack of error handling. occasionally the code goes into error and I struggle to immediately understand what the problem is.
1st comments even in 10 years
I cant see the map just black!
❤❤
Set as reference option isn't available anymore
Replaced with "Baseline" and there is now also the "more like this" that only displays scenes of same path and frame.
Excelente video
That is so cool
Excellente!!!
i can't see the map for explore, i see only gray color in background, i need a extension vidio? Thank You.
that deployable antenna is very cool!
I have a little problem, i can't see the map for explore, i see only gray color in background, i need a extension like flash player? Thank You.
This may be caused by a browser caching issue. Please try clearing cookies and cached images from your browser. Close and restart the browser, then re-open Vertex and see if this helps. Another thing to try instead is to open Vertex using a different browser or in an incognito (Chrome), private (Firefox), or InPrivate (Edge) instance in the browser you are using. This may also be caused by a slow internet connection. If possible, please try to open Vertex using a different network with a faster connection.
Wow
Glad you liked it.
There’s only four comments lol
This is quite old and you prob wont see this but, Thanks for the help with school work! Edit: Im in year 12 btw
Glad it helped.
Here after more than 3 years
How can make this step after speckle filtering in SNAP? i can't export the result to make geocoding for Radarsat-1 (Amplitude image )
at 1:35 why do you choose "output beta0 band" ?
Thank you for your question. One of our developers responded to your question as follows: The terrain flattening formulas developed by David Small et al that are implemented in the Sentinel-1 toolbox requires Beta0 as input and result in Gamma0 outputs. For details, please refer to the following article (equation 26). Small, D., 2011. Flattening gamma: Radiometric terrain correction for SAR imagery. IEEE Transactions of Geoscience and Remote Sensing, 49(8):3081-3093.

thanks for the video. it's very interesting. Please. i have a question how can we exploit the radar images in the field of mineral exploration
It would be good to say few words why we do each of these steps.
Pretty cool
