Usage

read_pbf(path, post_process = TRUE, use_sf = TRUE)

path: a scalar character of the path to the pbf file
post_process: default TRUE. Apply post_process_pbf() to the pbf body.
use_sf: default TRUE. Whether or not to return an sf object.

Value

Either a data.frame, list, scalar integer, or sf object if post_process = TRUE and use_sf = TRUE.

See process_pbf() for more.

Examples

count_fp <- system.file("count.pbf", package = "arcpbf")
oid_fp <- system.file("ids.pbf", package = "arcpbf")
tbl_fp <- system.file("small-table.pbf", package = "arcpbf")
fc_fp <- system.file("small-points.pbf", package = "arcpbf")
