Hi ​@Evangelia Efi Konstantinidou 

I believe support will be able to assist you best, therefore I have opened a support ticket on your behalf and copied the email you have used here on Planet Community. 

To others facing the same/ similar issue:

 

If the 'harmonized' indication is not present in the .tif file name and in the corresponding manifest.json file, then the image product is not harmonized, even if you selected 'Harmonized' during the ordering process.

The 'Composite' option and 'Harmonized' option serve different purposes and can be used independently. The 'Composite' option is used to create a single image from multiple overlapping images, while the 'Harmonized' option is used to adjust the images to a common radiometric scale, which is useful when comparing images from different dates or different sensors.

If you want your images to be both composited and harmonized, you should select both options during the ordering process. The resulting product should have both 'composite' and 'harmonized' indications in the file name and manifest.json file.

You can find more information on our harmonization tool here which may help explain the tools and processing further.

Hi Elyhienrich and thanks for the communication.

What you describe aligns with my understanding of the tools ‘composite’ and ‘harmonize’ while ordering a product in the Explorer app. I did following experiment to test 4 scenarios;

4 product downloads using the same ROI polygon:

1. a product consisting of 2 scenes, hamronized AND Composite
2. a product consisiting of 2 scenes, harmonized NOT Composite
3. a product consisitng of 1 scene,  hamronized AND Composite
4. a product consisitng of 1 scene,  hamronized NOT Composite*

*‘Compositing’ a single-scene product was done for reasons of completeness of the method

The downloaded products have indication ‘harmonized’ in the manifest.json file only for instances (2) and (4), which indicates that in this experiment, the application of tool ‘Composite’ cancels out tool ‘Harmonize’.

As I mentioned in earlier posts, my workaround is not to use ‘Composite’ and do the mosaicking on the local machine.

Best regards,

Efi
