H3 Cell parent token string. If the H3 Cell is invalid or parent resolution is higher than given cell, the query will produce an empty result.

Examples

The following example calculates H3 cell parent.

print parent_cell = geo_h3cell_parent('862a1072fffffff')

Output

The following example calculates cell parent at level 1.

print parent_cell = geo_h3cell_parent('862a1072fffffff', 1)

Output

The following example calculates an array of input H3 cell with its parent.

print parent_res = geo_h3cell_level(geo_h3cell_parent((geo_point_to_h3cell(1,1,10))))

Output

The following example calculates H3 cell level.

print parent_res = geo_h3cell_level(geo_h3cell_parent(geo_point_to_h3cell(1,1,10), 3))

Output

The following example produces an empty result because of the invalid cell input.

print invalid = isempty(geo_h3cell_parent('123'))

Output

The following example produces an empty result because of the invalid parent resolution.

print invalid = isempty(geo_h3cell_parent('862a1072fffffff', 100))

Output

The following example produces an empty result because parent can't be of a higher resolution than child.

print invalid = isempty(geo_h3cell_parent('862a1072fffffff', 15))
