ee_as_sf: Convert an EE table in a sf object

Description

Convert an EE table in a sf object

Usage

ee_as_sf(x)

Arguments

x

EE table to be converted into a sf object.

Value

An sf class object, see Details.

Details

Export large spatial objects it preferable to create export pipelines by using ee$batch$Export$table$* and rgee::ee_download_* instead of using ee_as_sf. See Client vs Server documentation for details.

Examples

# NOT RUN {
library(rgee)
ee_reattach() # reattach ee as a reserved word
ee_Initialize()
