We are excited to announce the release of ESA SNAP 12, marking 10 years since the very first release of the Sentinel Application Platform on 5 May 2015. The new version introduces significant updates for SAR, optical, and atmospheric data processing workflows. Here’s a breakdown of what’s new: :wrench: Core Enhancements: Updates to JDK21 showing…

Thank you for the update/information, Diana. Thank you very much, and congratulations to the SNAP team for all the involved work in the last 10 years!

Cheers!

Hey! Congrats for the release. It is great to have to updated version. Especially I’m happy of the JDK 21 update. Finally, SNAP uses a recent Java version.

But I have to report also a first issue. When try the raster to vector operation I found issues.

I have simply used B1 of Sentinel-2 and the following parameters for the quantification.

<parameters>
    <bandName>B1</bandName>
    <intervalsMap class="java.util.HashMap">1,0.0,0.15;2,0.15,0.4;3,0.4,1.3;</intervalsMap>
</parameters>

Which leads to this result:

So far so good.

But when using this result with the RTV operator the result it not usable.
The shapes are not present, and the geo-location is wrong.

The original location is 1. The converted_band has already some border. While the product 2 which contains the converted_band is at a different location. Together with product 3, the final RTV product.
The shapes, as masks and geometrys, look like this:

Depending on the zoom level the shapes mask can look like

The raster vectors_band is completely empty.

I’ve used the product S2A_MSIL1C_20230627T105621_N0509_R094_T30SVG_20230627T162159

Additional feedback:

  1. It would be good to let the user store presets for the intervals. This would allow to use the same values easily. It was already now annoying to enter the values again and again.
  2. The quantification operator has the target product suffix ‘_rl’. I think ‘_quant’ could be more meaningful.
  3. Besides using the raster to vector as operator it should be possible to use them in place on a product and let them only generate the vector. Like Band Maths.

Thanks again for the release.
Ciao
Marco
