There’s simple approach for LOS decomposition published here (see Appendix):

mid_lat = str2double(facility(3065:3084));

mid_lat = str2double(summary(123:134));
mid_lon = str2double(summary(139:148));

I have troubles importing ALOS-1 in CEOS format.

I have problems while updating stack of already processed Sentinel-1 images. The error occurs after “Reramping TOPS Slave Images” starts. Also, I’ve noticed several “Permission Denied” messages under Windows:
Warning: File not found or permission denied

while processing Sentinel-1A/B interferograms I get following error:
Invalid file identifier. Use fopen to generate a valid file identifier.

Thanks.

for now, you should use only one type of the orbit – ascending or descending. Generally, minimum of 20 images is advised to perform PSInSAR analysis, but you might find also lower number of images suitable, however as you said – the more the better.

should Coherence Map Generation be performed?

Undefined function or variable “FName”.

pcodes version: 8-Aug-2016, log attached

I get “Not enough input arguments.” msg when saving Final Fine APS from processing of Sentinel-1 images.

while starting a new set of Sentinel-1 images I get:

Undefined function or variable ‘FileMasterParam’.
Reference to non-existent field ‘FlagSequence’.

Related files are attached. I’ve encountered this issue after updating (with “Update” option) a set of already processed images fails due to unknown reason.

Have a nice day

I get “Index exceeds matrix dimensions.” when updating stack of Radarsat-2 images for new acquisition.

while updating set of already processed Sentinel-1 images, I couldn’t perform it using “Update” option in SLC DATA Processing window. .mat and .log file attached.

Thanks

I get “Reference to non-existent field ‘CreationDate'” while opening folder processed previously.

Thanks

while selecting area for processing Radarsat-2 SLCs I get different result in extracted Master image.

Thanks for your advice.

Matus

Many thanks to you Yuxiao,

Thanks

I’ve found some strange error while working with SLC IW images from Sentinel-1 usually starting from November, 2015. Images from >Nov,2015 in more than one track have grayed out intensity and corregistration fails everytime I am using them.

Few examples are:
SLC IW from ASCENDING track with relativeorbitnumber:102 over the area centered…[Read more]

I would suggest to be patient. As in other processing windows you have to be familiar with what you are doing. Any of us that started with SARproZ has been experimenting with it for months until obtaining some reliable results, as its not a magic box where you press buttons and get outputs (like any other InSAR related software). First…[Read more]

it depends on what you’re trying to accomplish (single interferogram? multiple interferograms? multi-temporal InSAR?). The easiest way would be to follow tutorials and manual stored at: http://www.sarproz.com/material-download/ and http://www.sarproz.com/software-manual/ and get started with Small Area Processing module first.

Cheers,

while etracting Master Sentinel-1 image I get:

when the duplicates are deleted from SLC directory, it is possible to continue with proccesing.

black borders has gone, thank you, however, footprints are now slightly different and they are not covering whole AOI. I’ll try to search for adjacent track based on Daniele’s suggestion from other forum thread and I’ll continue on testing.

Cheers

thank you all for a good job and for putting your effort into developing S1 TOPS processing and adaptive mask. I’ve been eagerly following updates last days and I’ve tried to produce coregistrated stack of 8 S1 images. However, in versions from last days (7-Aug, 12-Aug, 14-aug) I get half of extracted Master and Slave images black. I was…[Read more]
