Download satellite imagery and climate/atmospheric datasets using the SkyWatch API based on a query output object obtained from the querySW function. The API returns data with coordinate reference CRS=" +proj=utm +zone=50 +datum=WGS84 +units=m +no_defs +ellps=WGS84 +towgs84=0,0,0". This function returns either the entire scene if region is not specified, or part of the scene cropped to the specified region with the same coordinate reference. The downloaded data are returned as a raster stack Object.
