Hello everyone,
I am currently working with a Planet SuperDove image to quantify the surface area covered by sargassum using a mask. I understand that SNAP provides the masked area, but I’m unsure whether the program calculates the area directly or if it simply provides pixel values that I need to multiply by the pixel size and area of interest. Could someone please guide me on this?
You can invoke from the menu Raster / Masks / Mask Area ...
This will compute the square kilometres of the mask. The area is calculated for each pixel individually and summed up.

Hi,
Would the situation be the same if the program only provides me with the Number of Masks pixels and the Mask Area (km²)?
Yes, the area per pixel is only smaller than 0.001km² and not displayed in the GUI.
Maybe the pixel area is 0.0004km² or something like that.
