Hexagonal hierarchical geospatial indexing system.

A little magic binding H3 for Series.

Notes

Based on pandas style, APIs are designed as follows:

Remove the prefix h3_ of the original H3 API. e.g. h3.cell_to_latlng() → to_points()
Use to_ prefix for the conversion between H3 cell int and str. e.g. h3.int_to_str() → to_str()
Use is_ prefix for the validation of H3 cell. e.g. h3.is_valid_cell() → is_valid()

Attributes

area: Compute the spherical surface area of a specific H3 cell.
is_pentagon: Identify if H3 cell is a pentagon.
is_res_class_III: Determine if cell has orientation “Class II” or “Class III”.
is_valid: Validates H3 cell (hexagon or pentagon).
resolution: Return the resolution of H3 cell.

Methods

`to_center_child`([resolution])	Get the center child of cell.
`to_children`([resolution])	Get the children of cell.
`to_int`()	Converts hexadecimal string H3 cell index to 64-bit integer.
`to_parent`([resolution])	Get the parent of cell.
`to_points`()	Return the center `Point` of H3 cell.
`to_polygons`()	Return `Polygon` to describe the cell boundary.
`to_str`()	Converts 64-bit integer H3 cell index to hexadecimal string.
