I am doing a research of monitoring algal blooms in inland water bodies
How can i extract the pixel values of Chlorophyll a and Total Suspended Matter from the processed C2RCC images in SNAP. I have attached geotiff images of the two parameters.
Hello dear.
The idea of monitoring is clear, but can you explain a little bit the technical method you have used?

Hello Abraham,
Your query has been clearly discussed here. (http://bit.ly/39Y8KPr)

Hello,
It is better if you keep the files has netcdf. Using Snap, you can use the "pin" function, you could add a pin randomly to your map on SNAP, then you open the "pin manager" in the menu and you will see that you could add Lat and Lon in the first columns. You just have to export the extraction in a CSV file (located on the left of the "pin manager" window. ALternatively, you can create your own csv file with the lat and long information and upload them in SNAP, here is a youtbue video with more information: https://www.youtube.com/watch?v=5znAQH6vrLs
Do not hesitate if you have other questions, we do use SNAP a lot at my laboratory. There are also other software that work pretty well for extracting information from Sentinel-2&3 and Landsat-8 (ACOLITE and POLYMER), these application are developed by research laboratory. The can do batch processing under linux.
