The mapbox cheap ruler algorithm is intended to provide approximate yet very fast distance calculations within small areas (tens to a few hundred kilometres across). Some techniques grab the users' attention, but often don't add anything useful to the message the map is trying to convey (such as 3D tricks, or flashy/gratuitous images and infographics). Giving your maps more visual impact There are many ways to add more 'visual impact' to your maps. Distance measures currently implemented are Haversine, Vincenty (spherical and elliptical)), the very fast mapbox cheap ruler (see their blog post), and the “reference” implementation of Karney (2013), as implemented in the package sf. Everything's big in Texas - at least that's what they say Therefore let's have a bit of graphical fun, and use Texas as a unit of measure (let's call it a 'tex'). The Map in my Head (Wrong) My gut instincts. #> 10 10Īll outputs are distances in metres, calculated with a variety of spherical and elliptical distance measures. ![]() The 'cheap' measure is inaccurate over such #> large distances, you'd likely be better using a different 'measure'.
