How to copy a partial image from a whole image at S-1 SNAP? I tried may times, but it failed

Anyone could help me about this?

Do you mean subsetting? If you have a S1 GRD product you can just create a subset from the raster menu.
If you have a S1 SLC product, you can use the TOPS Split operator (in raster -> Sentinel-1 TOPS menu) if you want a select of the subswaths and bursts and want to continue working with burst data or you can deburst (in raster -> Sentinel-1 TOPS menu) the data and then run subset as in the GRD case.

how to save GeoTif with UTM map project?

#4

Actually there is no magic about it.
Reproject to UTM and select as format ‘GeoTIFF’. That’s it.

Thanks for reply,
How you setup the Reprojection parameters, I got error on that
“A problem occurred during the target product initialisation.
Type: OperatorExecption
Message: SAR product should be terrain corrected or ellipsoid corrected”

#6

Yes, if you only reproject an image in SAR geometry, the result will not put every pixel in the correct place on the ground. Use terrain correction when a DEM is available or ellipsoid correction when not. You can still choose a UTM projection and output to GeoTiff as Marco has shown.

You mean I need to do step “SAR-Simulation Terrain Correction” first???
Can you point me the article “GeoTiff as Marco has show”, I am looking for that.

#8

Actually, I want to cut a small area from the whole image of S-1 SLC product. Then export it as Gamma format file.

#9

It is not possible to subset the S-1 SLC before deburst & merge. You can select individual bursts but you cannot retrieve a partial burst.

Thanks for your help

is it possible to copy from one product into another? i.e i have a product of vertical displacement i.e product 1 and want to copy into another product i.e 2. because i want to use these both for band math operation for which it is necessary that both products should be in the same product?
