H3.jl ⬡

Documentation	Build Status

H3.jl provides Julia bindings to h3, a hexagonal, hierarchical geospatial indexing system. See the source code for the underlying C library at https://github.com/uber/h3.

using H3.API

base = latLngToCell(LatLng(deg2rad(0), deg2rad(0)), 5)
rings = gridDisk(base, 1)

x = Vector{Float64}()
y = Vector{Float64}()
for boundary in cellToBoundary.(rings), geo in boundary
    push!(x, geo.lng)
    push!(y, geo.lat)
end

using UnicodePlots
@info :plot scatterplot(x, y)
