I need to map a small area in ALGERIA which has undergone a strong impermiablisation or artificialisation of the ground, and I need to know how I can map it using Landsat-8 images What bands, what indices (NDVI, NDWI ...), what statistics and which classification can i use?. What if it can only be done by GOOGLE EARTH ENGINE ? Thank you
