CCD and Displacement Mapping with Sentinel InSAR Data and procedure
I am using ERDAS 2016 with IMAGINE SAR INTERFEROMETRY module to produce from Sentinel 1A InSAR data
But when in define input file both CCD and Displacement Wizard dialog of ERDAS it gives me the error "Can't allocate Space".
The Sentinel 1A inSAR input images has two bands (Magnitude and Phase) and are well readable in Sentinel Toolbox software.
However in ERDAS it gives the above message and also SAR node not present. Message
My questions are:
kindly note that my purpose of is to produce above 3 maps. Based on this goal kingly provide me the best parameters.
Solved! Go to Solution.

If you are using Sentinel-1 data you should use the Mosaic Series CCD tool. I am providing a couple of links to the Hexagon Geospatial documentation portal for helpful information about this tool. I would encourage you to review the documentation about the Mosaic Series CCD tool and how it ingests Sentinel-1 data.
ERDAS IMAGINE 2016 v16.1 does not currently support Sentinel-1 data in the Differential InSAR tool.
We suspect that you are receiving the “Can’t allocate Space” error due selecting an incorrect input data file. The software is expecting an XML metadata file for Sentinel-1 data.
I will send you a message to provide you with additional documentation about Sentinel-1 interferometry.

Thanks for your reply. But I am about to place an order for ERDAS 2016 with InSAR and some other Add-on modules.
Our goal is to process Sentenel Data for producing CCD and Distortion maps. Does it supports TerraSAR Data ?
However, my confusion still remains about which "parameters" to be defined ?
While downloading Sentienl -1 SLC (paired) data to make sure that, it works fine with Mosaic Series CCD and Sentinel-1 Project.
It takes about 5 hour to downlaod a single data set and I need to download huge data sets.
Thanks for your support

Both S1A and S1B can be used with the Mosaic Series CCD tool. You should choose the SLC product. The polarization needs to be the same for both images in the interferometric pair and you should select the IW (Interferometric Wide swath) acquisition mode.
TerraSAR-X data is supported in the CCD and Differential InSAR tools.
The Coregister Radar Images (Coregister Image Pair) tool is used to precisely coregister two radar images by resampling the Match File to the Reference File. The Stack Coregister tool automatically coregisters each radar image to the first (oldest) image in the stack. This tool was not available in ERDAS IMAGINE 2014.
