Radarsat-2 StereoAnalyst and DEM

Recommended Posts

Hi,

Does anyone know the procedure to create a block project for StereoAnalyst use with RadarSAT-2 HH SLC images? Have bunch of those images and they are not stereo-pair type. Also have to extract a DEM and have terrible results …..does not look like DEM at all :(

So if someone can give me some hints

Any help would be greatly appreciated

Thank you

Yeh...

I forgat to mention the most important thing :)

Erdas, LPS to create a project

and trying to see in 3D in StereoAnalyst

thanks

yeah , use Leica Photogrametric suite (LPS) of ERDAS there get the module for make a block and work with all photogrametric process.

good luck.

But problem is I can't make block project with those type of images!

Can you suggest what kind of Geometric Model Category should I use

I think I tried them all

Thanks

NOTE form ERDAS

All these formats will work throughout the IMAGINE Radar Mapping Suite (RMS), except

for IMAGINE StereoSAR DEM, which only RadarSAT provides stereo pairs if radar

imagery.

None of these formats work within the LPS tools. You must use them within the

IMAGINE Radar Mapping Suite of tools.

Hem, too bad I never use ERDAS before

Thank you very much for taking you time to answer me

If I can’t make a project in LPS with RadarSat-2, can I maybe create a project in LPS with epipolars extracted from Radarsar-2?

If so, witch Geometric Model Category should I use?

Thank you again

Every photogrammetric software usually need certain parameter in order to doing photogrammetric tasks like DEM extraction or orthorectification, and "specific parameters" that I was mentioned before usually stored in the image metadata (in certain format too), so I think you should check does your data fulfill the software requirement or not, based on my experience, its often people trying to do some image analysis task without knowing the workflow or the requirements to do appropriate processing,

Can you point me in the right direction of the workflow for RadarSAT-2 images to extract a DEM and to see in 3D for stereoscopic work that I need to do

Thank you

I think for RADAR file you need to use this tool

it contains ;

IMAGINE OrthoRadar

IMAGINE Radar Interpreter

IMAGINE StereoSAR DEM

IMAGINE SAR Interferometry

I think stereo pair for SAR data use Imagine StereoSAR DEm tool  :cry:

:embarrassed:

just my two cent  :rolleyes:

May be first of all you must convert  SLC  to SGF. Because SLC type use for interferometric processing. But for stereo uses SGF and SGX types/

And then IMAGINE StereoSAR DEM

Can you tell me how do I do that?

I see there is a Radar Convert tool ...is it Domain conversion....Radiometric conversion...

Thank you

In my ERDAS 9.1 it's situated

Radar - Radar Intrepeter-Adjust Slant Range.

This  procedure in common calls slant to ground range conversion.

It will be better if you read before help for this procedure to correct processing your image. :).

Hi, I have a problem to generate DEM with interferometry, I need to convert the Radarsat images type 2 SGF to SLC. It is possible that process.
