Extra features #3

Closed gjmcn closed 3 years ago

Great to see this algorithm implemented in R.

I worked on the tile map paper. After developing the original algorithm, we considered a couple of extra features:

1) Repel non-neighbors 2) Allow using the concave hull of the centroids rather than the original boundary

These were not added in time for the paper, but are included in the demos:

I don't think these features are included in this package? If not, it might be nice to add them at some point?

Thanks for letting me know about these extra features! They are currently not included in this package, but I will definitely look into adding them in the future.

using this as R code: install.packages(c("tilemaps", "sf")) library(tilemaps) library(sf) library(dplyr) library(ggplot2) governors <- governors %>% mutate(tile_map = generate_map(geometry, square = FALSE, flat_topped = TRUE)) head(governors)

ggplot(governors) + geom_sf(aes(geometry = tile_map)) + geom_sf_text(aes(geometry = tile_map, label = abbreviation), fun.geometry = function(x) st_centroid(x)) + theme_void()

I am trying to build a Canadian Tile map. I got the geometry (lpr_000b16a_e.shp found https://open.canada.ca/data/en/dataset/47bd4f2e-1c77-49f8-8406-dc4dca64ee6b) from statistics Canada.

when I am using the R code above, I am getting this error: Error: Problem with mutate() input tile_map. x regions are not contiguous i Input tile_map is `generate_map(geometry, square = FALSE, flat_topped = TRUE)

How can I create a tile map of the Canada provinces?

Hi, I have opened a new issue (#4) to address this question.
