I am trying to mosaic multiple sentinel sar images in esa snap software. The scenes are acquired from two adjacent tracks. I used the tool S1 slice wizard in snap under radar tool menu. But my images didn't get mosaiced. I am attaching the screenshot of the output. Kindly advice.
I would like to draw your attention to Mosaicing tool in
Raster | Geometrical Operations menu. (*1)
Mosaicingtool. There are several tabs (as below) in the dialog window;
- [I/O Parameters] Read your Sentinel-1 images (.tiff) into
Source Productsby clicking on small plus icons. Set output directory and filename, along with the output format.
- [Map Projection Definition] I think you can leave it as WGS84, but you need to set the Pixel size (default size is 0.005). In my case original size was 0.000101356, but it can be upscaled (depending on how detail you want the output image).
- [Variables and conditions] I think at least you need to set Variables. Click on a small document icon, which calls up a dialog to choose the band.
- If all settings are done, click on [Run] and wait a while.
(*1) I honestly do not know about
S1 slice wizard, and have no positive experience with
SAR mosaic wizard tool in
Radar menu, when working with Sentinel-1 images.
If you want to use snappy, here's a link on how to do it.
