      Thanks Leslie. Glad it helped. This is just the tip of the iceberg. There is so many multispectral analyses you can easily implement in QGIS. cheers

    Is this imagery already atmospherically corrected?

      Hi, great question. No I did not address atmospheric correction in this video as it was more about using the basic raster tools in QGIS. The Sentinel product used in the example was L1C (which is what you get from EarthExplorer). L1C is top of atmosphere (TOA) reflectance with radiometric and geometric corrections. If I was using this product I would instead use the SCP plugin in QGIS to apply the DOS corrections. Alternatively, if I had used SCP in QGIS to download the imagery, which is my normal process, I could access the L2A product which is bottom of atmosphere (BOA) reflectance.

      @@spatial-exploration1478 Thank you for the reply! Does the L2A product not need to be corrected? I am new to QGIS and quite like the options for pre-processing but I am still learning about correcting images. I use Sentinel 2 imagery almost exclusively.
