I’m very new to Sen4CAP and I’m trying to figure out how to use this powerful set of processors for “historical” analysis. I mean: I’m interested in having L3A, L4A, L4B, and L4C products for a season in the past and not for the coming months.
Should I use Sen4CAP in automatic mode? If not, what should I do? Of course, I have to set up the data sources. Then I suppose I have to create one or more sites: which processors should I have to select for them?
I have some small areas: should I create a unique site or should I treat each of them as a separate site? In the latter case, what happens while downloading a source data intersecting more than a site? Will be the source data be downloaded as many times as the number of the intersected sites, or just once?
Can I have an estimation of the volume of data to be downloaded before starting the download? Is there a way to monitor which source data have been downloaded and which not yet? Is there a way to automatically delete raw data (Sentinel-1 SLC, Sentinel-2 L1C, etc.) after L2A product generation?
Are source data downloaded in chronological order (from older to newest)? And what happens with archived Sentinel data?
