Connection graph internal error (EC:250008) 22037 1
Started by Deleted User
I want to process a stack of S1A SLC for SBAS. I have 15 S1A SLC data. I first create the subset stack using the tool found under SARscape > Interferometric Stacking > Stacking Tools > Sample Selection SAR Geometry Data. Then I am running the process step of connection graph. The Principal Parameters set Delaunay 3D to True, and Allow Disconnected blocks to false. An error comes out : Connection graph internal error (EC:250008). Could you help me

Regarding subset of Sentinel 1 stack for SBAS 23947 11
Started by Deleted User
I am attempting to process a stack of S1A SLC for SBAS.
I face two issues regarding creating a subset in slant range.
1) From the tutorial here: http://sarmap.ch/tutorials/Getting_started.pdf
After generating the area subset, the extensions are _pwr (by default). However, I cannot ingest this file format in the SBAS flow. Am I supposed to edit the extension to _slc_list_pwr manually
2) From the tutorial here: http://sarmap.ch/tutorials/PS_Tutorial_V_0_9.pdf
In page 35, there is a supposedly a...

How can I find pixel spacing in azimuth and range and look angle from envi sarscape? 23007 1
Started by Deleted User
I have a quad-pol ALOS-PALSAR dataset, which I have read using Envi SarScape.
Now I find to read the header or where the following information is written:
pixel spacing azimuth
pixel spacing slant range
incidence angle scene centre
To use the following formula to calculate the number of looks:
I don't want to use `looks` button to estimate the number of looks automatically.
How can I read that data

Coregistration / Persistent Scatterers 22144 2
Started by Deleted User
Dear Colleagues:
I want to first coregister all TerraSAR-X SLC data by SARscape(5.0)->Basic->Coregistration before putting them into SARscape(5.0)->Interferometric Stacking->Persistent Scatterers. Finally, I got the correct SLC by visual checking.
As we know, the normal and temporal baselines are necessary in interferometric processing. However, these coregistered SLC data lose their original information about normal and temporal baselines. When I use SARscape(5.0)->Interferometry->Baseline Es...

I am processing a stack of Sentinel 1 radar images in Sarscape 5.2 in the second step of PS stacking an error comes out complaining FILE NOT FOUND referring to file: master......_slc_list_pwr_orb_hdr. I understand it is an orbital parameter file in "old" format. Such file is not generated during the process. Only file master...._slc_list_pwr_orb.sml is generated. Is it me doing something wrong

sigma-nought NaN&39;s on output 2369 0
Started by Deleted User
Hello,
I am in process of finding the backscatter coefficients (sigma-nought) values for SAR acquisitions from ERS-1/2, Envisat, and PALSAR using the Geometric and Radiometric Calibration tool in SARscape. I have processed all of these datasets however the Envisat SAR data is the only dataset that has yielded reasonable results in dB. The others (ERS-1/2 and PALSAR datasets) give NaN values on output for the entire scene. For these satellites, I also checked some of the intermediate files (ga...

focusing Radarsat data 1972 2
Started by Deleted User
Hello,
Does SARscape allow for focusing of level 0 Radarsat-1 data The only module in SARscape I have found that will handle Radarsat-1 data is the import standard formats module in Classic (SARscape --> Basic --> Import Data --> Standard formats). However, this apparently does not take raw, level 0, Radarsat-1 data, but rather higher level products.
Anybody know for sure whether SARscape can focus raw (level 0) Radarsat-1 data I downloaded this from one of the SAR repositories. The zip fi...

When reaching the Geocoding step, the PS Map (.shp and .kml files) is properly generated providing the information I'm interested in.

Using External DEMs with SARscape 3665 3
Started by Deleted User
Good morning,
In Geometric and Radiometrics process I am trying to use an external DEM to adjust the TSX SSC image geometry and to extract lay over effects.
I have my own DEM in GeoTIFF format (my study zone is Antarctica and a SRTM DEM it is not enough accurate over 60º).
There are several formats in the default menu but I have not found the way to use mine.
How can I afford the geometric correction Only .dem format it is supported.
Thanks in advance.

Tandem-X processing 2076 1
Started by Deleted User
Hi, does anyone know if the TDX processing implements the full solution for the helical orbit or does it assume that TDX satellites behave like a 'normal' tandem pair Also, is the Effective baseline estimated by SARScape a more accurate representation of the separation between the two antennas than the DLR metadata I assume this is the case but if the helical orbit is not considered then the DLR data should be more accurate.
Thanks,
I.
