Converts from an existing `GRASS` environment an arbitrary vector dataset into a sf object

Converts from an existing `GRASS` environment an arbitrary vector dataset into a sf object

Usage

gvec2sf(x, obj_name, gisdbase, location, gisdbase_exist = TRUE)

Arguments

x

sf object corresponding to the settings of the corresponding GRASS container

obj_name

name of GRASS layer

gisdbase

GRASS gisDbase folder

location

GRASS location name containing obj_name

gisdbase_exist

logical switch if the GRASS gisdbase folder exist default is TRUE

Note

have a look at the sf capabilities to read direct from sqlite
