GISSB
is a package that contains GIS functions in R for use in
Statistics Norway.
See the vignette for an introduction of how the functions can be used for network analysis in R: https://statisticsnorway.github.io/GISSB/articles/GISSB_vignette.html
You can install GISSB
from CRAN like so:
install.packages("GISSB")
If you want to install the development version of GISSB
from Github,
use this code:
devtools::install_github("statisticsnorway/GISSB")
Most of the functions in the GISSB package require that the Norwegian road network NVDB Ruteplan nettverksdatasett (National roads database - road network for routing) has been downloaded locally to your computer. The format of the file should be “FGDB 10.0”.
After the file has been downloaded it has to be read into R using the
sf
package:
vegnett <- sf::read_sf("vegnettRuteplan_FGDB_20221109.gdb", layer = "ruttger_link_geom")
turnrestrictions_geom <- sf::read_sf("vegnettRuteplan_FGDB_20221109.gdb", layer = "turnrestrictions_geom")
vegnett <- sf::read_sf("vegnettRuteplan_FGDB_20210528.gdb", layer = 'ERFKPS')
turnrestrictions_geom <- sf::read_sf("vegnettRuteplan_FGDB_20210528.gdb", layer = "ERFKPS_turns")
