Before You Start:
This lab summarizes the material learned in Lectures 8 – 10 and puts them to good use. We will apply the theory of SAR focusing from Lecture 8 to process a ALOS PALSAR L-band SAR image over Fairbanks, AK using the NASA/JPL-produced ISCE software. We will also geocode SAR images using both ISCE and the ASF-released MapReady software.
We will use the cloud-based Virtual SAR Lab for our work. The cloud-based environment allows you to work on this lab from any location as long as internet access is available. To use the Virtual SAR Lab, please make sure tha the following software is installed on your computers:
- VcXsrv (sourceforge.net/projects/vcxsrv/)
- Putty (www.chiark.greenend.org.uk/~sgtatham/putty/latest.html)
- WinSCP (winscp.net/eng/download.php)
Goals of this Lab:
While most modern SAR data are available to you in fully focused and easy to digest data formats, some of the historic data do still require processing by the end user to convert them into images that are ready for use in GIS systems. Hence, this lab will focus on how to focus raw SAR data into images and how to geocode these products and export them into GIS-ready formats. We will use the free and publicly available software tools ISCE (InSAR Scientific Computing Environment) and MapReady for processing. Both tools area available to you on a cloud-based Virtual SAR Lab that will be used in this class.
