Hello,

I have a question on the PlanetScope Harmonized surface reflectance data product’s metadata. Where in the metadata can I find an indication that the product is ‘harmonized’, as opposed to non-harmonized surface reflectance image products?

I know ‘harmonized’ is an option during product order but how can I verify that I indeed downloaded the desired type of imagery?

 

Thanks in advance,

Efi

Hello Eli! My name is Mariana and I am the Product Manager for PlanetScope images. Unfortunately, we don’t state specifically in the GeoTiff header that “harmonized” tool has been applied. You would be able to determine if the “harmonized” tool has been applied in two ways:

  1. The image GeoTiff name: e.g 20241205_083125_95_24ee_3B_AnalyticMS_SR_harmonized_clip.tif
  2. When you place an order, you will receive a manifest.json sidecar file. This file provides information of the folder structures, file names and how they are associated to each other. In this file you’ll have a GeoTiff file name and how it is associated to the asset you downloaded. In the path, you’d again have the file name with harmonized on it: e.g "path": "PSScene/20241205_083125_95_24ee_3B_AnalyticMS_SR_harmonized_clip.tif" 

If you look at the image GeoTiff and don’t see the term “harmonized” in the file name, the tool hasn’t been applied.

Dear Mariana,

Thanks for the feedback on my question.
For testing, I ordered a 'harmonized' PlanetScope product (I'm happy to provide order details upon request).

1. Indeed, after I extract the .zip folder that contains the full product, 'harmonized' is part of the .tif name. Although the term is not included in the name of the zipped folder.

2. Concerning inclusion of the term 'harmonized' in the manifest.json file available in the order link, the term 'harmonized' seems to not be included. The .tif file name indicated in the manifest.json is identical to the .zip folder name.

Just for reasons of completeness, another instance where 'harmonized' is indicated is in one of the .json files in the extracted product folder.

Thanks again for the input,
Efi
