ArcGIS-Sentinel2-Download-Tools | ArcGIS Python Toolbox for Search & Download of Sentinel-2

Download ZIP and extract its content to a local directory that can be reached by an ArcCatalog Folder Connection. Make sure that the original file structure is preserved (relative paths); all referenced files have to be properly placed with respect to the main Toolbox files (.pyt, *.xml), by name sensub.py and all *.lyr files within their respective subdirectory. 📓 Note: Do not simply drag and drop the Toolbox icon to a desired ArcCatalog Folder Connection (e.g. "My Toolboxes"), because by doing so ArcCatalog copies only the Toolbox .pyt file in conjunction with its belonging *.xml help files but leaves out all other dependent files!
Before using the tools, it is highly advised to read the respective Item Description of the Toolbox and of each tool in advance (see respective context menu in ArcMap), particularly the Usage of each tool (also reachable from each Tool Help). Amongst others, the Usage of the Search tool introductorily explains some general ArcMap settings that have to be carried out in advance. When running the parameter form of a particular tool, consult the respective Parameter Explanation shown in the side panel (button "Show Help >>" opens the side panel).
