Structs
| GeoCoord | Represent a coordinate |
Functions
| degs_to_rads | Convert degrees to radians |
| edge_length_km | Return the edge length of a hexagon at a particular resolution in kilometers. |
| edge_length_m | Return the edge length of a hexagon at a particular resolution in meters. |
| geo_to_h3 | Convert a GeoCoord to a H3 index. |
| get_res_0_indexes | All the resolution 0 H3 indexes. |
| h3_to_geo | Convert a H3 index value to a GeoCoord |
| h3_to_geo_boundary | Convert a H3 index value to a GeoBoundary which are a vector of points that describe a H3 Index's boundary |
| h3_get_resolution | Return the resolution of a H3 index |
| h3_is_valid | Determine if H3 index is valid |
| h3_indexes_are_neighbors | Determine if two H3 indexes are neighbors |
| h3_is_pentagon | Determine if the specified H3 index is a pentagon. |
| h3_get_base_cell | Get the number of the base cell for a given H3 index |
| h3_distance | Get the grid distance between two hex indexes. This function may fail to find the distance between two indexes if they are very far apart or on opposite sides of a pentagon. |
| h3_to_parent | Returns the parent (coarser) index containing h3. |
| h3_to_children | Returns children indexes contained by the given index at the given resolution. |
| hex_area_km_2 | Determine the area of a hexagon at a particular resolution. |
| hex_range | |
| hex_range_distances | |
| k_ring | Get all hexagons in a k-ring around a given center. The order of the hexagons is undefined. |
| k_ring_distances | Get all hexagons in a k-ring around a given center, in an array of arrays ordered by distance from the origin. The order of the hexagons within each ring is undefined. |
| max_h3_to_children_size | Returns the size of the array needed by h3ToChildren for these inputs. |
| num_hexagons | Return the number of hexagons at a particular resolution. |
| polyfill | Get all hexagons with centers contained in a given polygon. The polygon is specified with GeoJson semantics as an array of loops. The first loop is the perimeter of the polygon, and subsequent loops are expected to be holes. |
| rads_to_degs | Convert radians to degrees |
| res_0_index_count | Number of resolution 0 H3 indexes. |
Type Definitions
| H3Index | A H3 index value a unique address of a hexagon or more unlikely a pentagon. |
| Resolution | A resolution that ranges from 0 to 15. |
