in the past months we have been working on many small things and some major changes. It is not time yet to release the major changes, but it is worth to focus on the small improvements, now available in the new Sarproz version.
* VERY IMPORTANT: we have implemented some changes in the licensing system for Linux. Now you should be able to run Sarproz in Linux without the need to input a sudo password. However, we may need to update your license. If after the update the software won’t run because of license issues, please send the license.key file to licensing at sarproz dot com (note: if the software fails to start, the license.key is modified with the infos we need for the update. Please send the modified license.key file, not an older copy you stored somewhere else). We will update your license as soon as possible. To keep working in the meanwhile, you will need to manually re-extract the older Sarproz version (which is saved in the “archive” folder, inside the Sarproz directory). Note: we did not test all linux distributions, so, your feedback will be important.
* An ongoing major change, which is now partially available, is the Sarproz command line execution. It is currently developed up to the interferograms generation. In attachment to this post you can find a description of the concept and a description of the input parameters file used to set the processing options.
* New SRTM data repository. Recently, a webpage that Sarproz was using to download SRTM data went offline. We changed it to a new one. We also included a message that specifies if a SRTM tile is all zeros (the default consequence of an unavailable SRTM file).
* New CEOS data reader. We have tried to collect the common syntax among ERS, ALOS 1 and 2, RadarSat 1 and 2 in order to facilitate managing exceptional cases. An example was dealing with old Radarsat data which were missing orbital data. It will also be used to import more sensors (as Risat)
* A new flag in the “Single Interferogram Processing” module allows you to plot an interferogram after removing the corresponding APS (if previously processed). It’s called “APS Rem.” and it is located in the “Results Visualization & Export” frame.
* Changes are ongoing also in the coregistration section of the “SLC Data Processing” module. They are mainly in preparation for a faster processing of Sentinel data. You can now use an external DEM to refine the coregistration in the SLC processing section, without the need to refine it later in a second stage. Careful: this is a good choice only when orbital data are precise. For old satellites as ERS, it is better to perform a geocoding correction before using an external DEM to refine the coregistration.
* Various TOPS small updates and bug fixes are includes as well
