geo_s2cell_to_central_point(s2cell)

Parameters

NameTypeRequiredDescription
s2cellstring✔️S2 cell token value as it was calculated by geo_point_to_s2cell(). The S2 cell token maximum string length is 16 characters.

Returns

The geospatial coordinate values in GeoJSON Format and of a dynamic data type. If the S2 cell token is invalid, the query will produce a null result.

Examples

print point = geo_s2cell_to_central_point("1234567")
| extend coordinates = point.coordinates
| extend longitude = coordinates[0], latitude = coordinates[1]
