gcvt's Introduction

gcvt

Work in progress (imagine a web1.0 yellow roadwork sign here).

The goal of gcvt is to provide data and functions for visualising road networks. Specifically it is focussed on the TEN-T European road network.

Installation

You can install gcvt from github with:

# install.packages("devtools")
devtools::install_github("IntegratedTransportPlanning/gcvt")

Apps

This repo contains a number of shiny apps that view our data in different ways. The two most developed are combined_viewer_mapbox and combined_viewer_leaflet.

The leaflet version is currently less buggy. The mapbox version has link offsetting (so you can see the direction of links).

To run the apps locally use:

shiny::runApp("R/combined_viewer_leaflet/")

Mapbox app

The mapbox app requires some additional setup:

cd R/combined_viewer_mapbox
npm install
npm run build
