Get the date of a EE ImageCollection

ee_get_date_ic(x, time_end = FALSE)

Arguments

x

ee$ImageCollection object

time_end

Logical. If TRUE, the system:time_end property is also returned. See details.

Value

A data.frame with the columns: id (ID of the image), time_start, and time_end (only if the argument time_end is set as TRUE). The number of rows depends on the number of images (ee$ImageCollection$size).

Details

system:time_start Sets the start period of data acquisition while system:time_end does the same for the end period. See the Earth Engine glossary for getting more information.
