mission-across-iow

What's the easiest route to cross the Isle of Wight on foot in a straight line?

Purpose

Experimental work in progress: an R Shiny app to let users assess the 'difficulty' of straight-line walking routes across the Isle of Wight, UK, given obstructions (waterways, buildings, barriers, etc).

Inspired by Tom 'GeoWizard' Davies's attempts to cross countries, like Wales, in a straight line on foot.

Use the app

The app will be hosted on shinyapps.io when ready. In the meantime, you can download and test drive it from your R session with:

shiny::runGitHub(
  username = "matt-dray",
  repo = "mission-across-iow",
  subdir = "mission-across-iow",
  ref = "main"
)

It'll take a moment to download. See the mission-across-iow/global.R file for the packages you'll want to install.

Development

The ultimate goal is to use Leaflet Draw via {leaflet.extras} to let users draw a line, rather than provide points. Also I'll prettify things with (probably) {bslib}.
