Co-Registration 167 0
Started by Ramesh babu
Hi. I am new to SAR data processing. I want to do change detection between two SAR images taken by same satellite sensor but their incidence angle and viewing geometry may vary. Can I use SARScape co-registration for these images before attempting change detection. I read in SarScape documentation that for co-registration the viewing geometry and incidence angle should be same. So How do I go forward in this case.

Export PS Points to Google Earth 3125 1
Started by Nathaniel Schaefer
Thus far I have attempted to create and export kml files to Google Earth, but they have been much too large to be successful. As a workaround, I have been chipping the .png file to Google Earth and viewing the preliminary results that way. But with this method, point resolution is low and there is always at least a 5 meter offset from objects. Can anyone suggest a different way to view results Or am I doing something incorrect Thanks, Nate

Geocoding takes too long 799 0
Started by maria.przylucka
I try to perform DInSAR Dispalcement Workflow on two Sentinel-1 scenes. Before, during import, I used the shp file with the area of interest boundaries, so the scenes are cut to smaller area. All steps are performed fine. During GCP Selection, I added manualy around 40 points, evenly distributed throughout the image, omitting places of poor coherence. The workflow seems to stop moving forward during 'Phase to Displacement Convertion'. I see the process bar with 'Geocoding &91;INTERF_out_cc&93...

Refined Lee filter 1265 0
Started by Omar Mauri
Hello everyone, I'm comparing the Intensity Processing operators available in SARSCAPE and in SNAP. I'm running the Refined Lee filter via SARSCAPE over S-1 GRDH data (and other commercial images) in order to despecke the image. The results are very bad comparing to SNAP. Which is a reason why in SNAP the Refined Lee is a very good speckle filter while in SARSCAPE it doesn't work at all Thanks

PSinSAR processing issue 4347 8
Started by Corsabrin
Hi guys, I am trying to process 8 images from S1A for PSinSAR in sarscape. I understand at least 20 images is recommended. In my test, during the First Inversion step, the processing is stuck at: 'preliminary candidates selection' for quite some time. I have been waiting at this step for about 24 hours. Anyone has any idea what is going on Do I continue waiting or is there already a processing error Or is it because I need to use > 20 SLCs
For your information, the preliminary candidates sele...

Hi, so I've been using ENVI 5.1 with SARScape. And I'm trying to open ALOS PALSAR-2 data from SARScape import tool but I always get an error. It says "LEADER FILE NOT FOUND PLEASE CHECK IF YOU HAVE SELECT THE RIGHT DATA TYPE". I have ALOS PALSAR-2 data level 1.1 with dual polarization (HH and HV) and the image is divided per each scan so I have some *IMG files. I've tried opening the IMG and LED file but it shows the same error message (cd: 70016). Can you tell me what's wrong I'm new...

Error Code 50000 PROCESS CANCELLED 3995 3
Started by Juan Garatachia
Hi, I have trying to process Sentinel 1 images with SBAS algorithm, I was able to get to Fist Inversion Step, so in this step after a time, appears a error mesagge wich indicates that the process has been cancelled. I have investigated in the error catalogue, so, the result is that when this code appears it means that the user cancells the process or a parallel process has been started in other window. Neither is my case. Can someone guide me about it Thank´s
