Here we see three examples from Cape Town for the three different versions of resolutions of Copernicus Sentinel-2 (10m, 20m, 60m). The 60m data offers a glimpse on the outlines of the harbour (and potentially the piers) and you may identify the stadium in Greenpoint. Signal Hill may also be identified. The 20m data offers far more detail; The stadium in Greenpoint is well defined, as well as the harbour and you may also take note of some details such as individual ships. 10m offers even more details – the landscape of the city is well defined, far better than in the 20m data, whilst in the 60m data the landscape of the city is absolutely invisible(e.g. the cities infrastructure such as roads). What level of spatial detail do you need for your application? Keep in mind, that the spectral resolution of the images changes with the change in spatial resolution (10m = 4 bands, 20m = 9 bands, 60m = 11bands). This is crucial for your application and changes the mapping and analysis as it will enable more or less differentiation of surface cover materials (e.g. mapping iron-bearing ore vs. mapping goethite, jarosite and hematite).
