gvec2sf function

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

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

Examples

run = FALSE
if (run) {
## example 
require(sf)
require(sp)
require(link2GI)
data(meuse)
meuse_sf = st_as_sf(meuse, 
                    coords = c('x', 'y'), 
                    crs = 28992, 
                    agr = 'constant')

# write data to GRASS and create gisdbase
sf2gvec(x = meuse_sf,
        obj_name = 'meuse_R-G',
        gisdbase = '~/temp3/',
        location = 'project1')

# read from existing GRASS          
gvec2sf(x = meuse_sf,
        obj_name = 'meuse_r_g',
        gisdbase = '~/temp3',       
        location = 'project1')

}
