getSentinel_query queries the Copernicus Open Access Hubs for Sentinel data by some basic input search parameters. The function returns a data frame that can be further filtered.

getSentinel_query(time_range, platform, aoi = NULL, username = NULL,
  password = NULL, hub = "auto", verbose = TRUE)



character, containing two elements: the query's starting date and stopping date, formatted "YYYY-MM-DD", e.g. "2017-05-15"


character, identifies the platform. Either "Sentinel-1", "Sentinel-2" or "Sentinel-3".


sfc_POLYGON or SpatialPolygons or matrix, representing a single multi-point (at least three points) polygon of your area-of-interest (AOI). If it is a matrix, it has to have two columns (longitude and latitude) and at least three rows (each row representing one corner coordinate). If its projection is not +proj=longlat +datum=WGS84 +no_defs, it is reprojected to the latter. Use set_aoi instead to once define an AOI globally for all queries within the running session. If aoi is undefined, the AOI that has been set using set_aoi is used.


character, a valid user name to the ESA Copernicus Open Access Hub. If NULL (default), the session-wide login credentials are used (see login_CopHub for details on registration).


character, the password to the specified user account. If NULL (default) and no seesion-wide password is defined, it is asked interactively ((see login_CopHub for details on registration).


character, either "auto" to access the Copernicus Open Access Hubs by platform input, "operational" to look for ESA's operational products from the Open Hub, "pre-ops" to look for pre-operational products from the Pre-Ops Hub (e.g. currently all Sentinel-3 products), or an valid API URL. Default is "auto".


logical, if TRUE, details on the function's progress will be visibile on the console. Default is TRUE.


A data frame of records. Each row represents one record. The data frame can be further filtered by its columnwise attributes. Records can be handed to the other getSentinel functions for previewing and downloading.
