I am working with the Ocean Color SMI: Standard Mapped Image MODIS Aqua Data dataset.
Using the Sea Surface Temperature band, I am trying to assign the value "0" to any pixel in my region that has a value less than 30. Conversely, I need to assign a "1" to a pixel that has a value greater than or equal to 30. Essentially, some sort of binary process on the pixel data so that then when I visualize the map, there will be only two colors, the "0" and the "1."
How can I achieve this?
