I recently went on a trip to Honolulu, Hawaii, and was quite fascinated by some of the paper maps that I saw there. I also saw a Tableau visualization by Alexander Varlamov and got curious about building elevation contour maps for Hawaiian islands in R! Below you will find the contour maps for the eight Hawaiian islands that make up the state of Hawaii and an animation visualizing the 20 ft contours for Oahu.
I tried creating a Shiny app to mimic what Alexander Varlamov posted on Reddit. It's not as slick as Alexander's visualization, but it's my humble attempt at recreating it.
There is an island called Hawaii in the state of Hawaii!
I want to thank Alexander Varlamov for the inspiration and Kyle Walker for his mapgl R package that I have used heavily in this project.
