Projection deviation
Posted: Tue Apr 23, 2019 12:14 pm
Dear François,
I was checking my S3A-OLCI images after processing with Polymer 4.10 and I realized that for a few number of images (~2 of 320, I am still checking it) my point moved from the correct location. I downloaded some L2 OLCI images processed with Baseline AC (BAC) from CODA website to check it.
In the figure attached you can see 4 images from BAC (number 1 to 4) and 4 images from Polymer (number 5 to 8). The date of 05/June/2017 (number 3 for BAC and number 7 for Polymer), for example, is possible to observe the point 'Pin 2' moved to the left on the Polymer image.
- the coordinates are the same for the 8 images.
- the pin is moved for all bands.
Have you seen anything like this before?
Do you have some suggestion about what could be the cause for this deviation?
Thank you for the attention and help you are giving,
Joao Santos.
