Get Started
Downloading the data with getremotedata is a simple two-steps workflow :
-
With the function
grd_get_url(), get the URL(s) of the data for :- a collection : see previous section,
- (eventually) variables,
- (eventually) a region of interest,
- (eventually) a time range.
With any data download function (e.g.
httr::GET()oropendapr::odr_download_data()), download the data.
Additional functions include : list collection available for download ( gdr_list_collections() ), list variables available for the collections that have variables ( gdr_list_variables() )
Example
Have a look at the vignette("get-started") for a data download, import and plot workflow !
