    Introduction to h3

    + + + Source: vignettes/h3.Rmd + + +
    + + + +

    The package h3 provides R bindings for H3, a hexagonal hierarchical spatial indexing system.

    +

    See also H3 Tutorial.

    +
    +

    +Core Functions

    +
    library(h3)
+
+# Index a lat/lng point to an H3 index
+coords <- c(37.5, -122.5)
+res <- 9
+
+(h3_index <- geo_to_h3(coords, res))
    +
    ## [1] "8928342e20fffff"
    +
    # Get the center of an H3 index as a lat/lng point
+h3_to_geo(h3_index)
    +
    ##           lat       lng
+## [1,] 37.50125 -122.5003
    +
    # Get the vertices of an H3 index as lat/lng points
+h3_to_geo_boundary(h3_index)
    +
    ## [[1]]
+##           lat       lng
+## [1,] 37.49974 -122.4990
+## [2,] 37.50142 -122.4980
+## [3,] 37.50293 -122.4992
+## [4,] 37.50275 -122.5016
+## [5,] 37.50107 -122.5026
+## [6,] 37.49956 -122.5014
    +

    Usually functions are vectorized:

    +
    (coords <- road_safety_greater_manchester[1:2, ])
    +
    ##        lat       lng
+## 1 53.62111 -2.461070
+## 2 53.61887 -2.458324
    +
    (h3_indexes <- geo_to_h3(coords, 8))
    +
    ## [1] "88195186b3fffff" "88195186b3fffff"
    +
    h3_to_geo_boundary(h3_indexes)
    +
    ## [[1]]
+##           lat       lng
+## [1,] 53.62557 -2.460912
+## [2,] 53.62432 -2.467959
+## [3,] 53.61988 -2.469062
+## [4,] 53.61670 -2.463119
+## [5,] 53.61796 -2.456073
+## [6,] 53.62239 -2.454970
+## 
+## [[2]]
+##           lat       lng
+## [1,] 53.62557 -2.460912
+## [2,] 53.62432 -2.467959
+## [3,] 53.61988 -2.469062
+## [4,] 53.61670 -2.463119
+## [5,] 53.61796 -2.456073
+## [6,] 53.62239 -2.454970
    +

    If sf is installed, you can get the polygons of H3 indexes like this:

    +
    h3_to_geo_boundary_sf(h3_indexes)
    +
    ## Simple feature collection with 2 features and 0 fields
+## geometry type:  POLYGON
+## dimension:      XY
+## bbox:           xmin: -2.469062 ymin: 53.6167 xmax: -2.45497 ymax: 53.62557
+## epsg (SRID):    4326
+## proj4string:    +proj=longlat +datum=WGS84 +no_defs

+## 1 POLYGON ((-2.460912 53.6255...
+## 2 POLYGON ((-2.460912 53.6255...
    +
    +
    +
