0 Replies and 167 Views 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.

1 Replies and 3125 Views 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

0 Replies and 799 Views 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...

0 Replies and 1265 Views 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

2 Replies and 643 Views Geocoding and Radiometric Cal - Mask out the sea  643  2 Started by  Omar Mauri Dear all, I'm working in intensity processing with S1. After the Geocoding and Radiometric Calibration SARSCAPE creates an image where the information over the sea is lost. I'd like to keep the sea area information over my image. Do you know how to achieve this result I'm missing the proper option. Thanks for your help

8 Replies and 4347 Views 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...

I would like to use the same set of refinement GCPs both for geometries. How can I convert GCPs created in descending slant range geometry to ascending slant range geometry Is there a tool to geocode slant range GCPs Thanks

3 Replies and 3995 Views 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
