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

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

Output

The following example returns a null result because of the invalid geohash input.

print geohash = geo_geohash_to_central_point("a")

Output

You can use the geohash value to create a deep-link URL to Bing Maps by pointing to the geohash center point:

// Use string concatenation to create Bing Map deep-link URL from a geo-point
let point_to_map_url = (_point:dynamic, _title:string) 
{
    strcat('https://www.bing.com/maps?sp=point.', _point.coordinates[1] ,'_', _point.coordinates[0], '_', url_encode(_title)) 
};
// Convert geohash to center point, and then use 'point_to_map_url' to create Bing Map deep-link
let geohash_to_map_url = (_geohash:string, _title:string)
{
    point_to_map_url(geo_geohash_to_central_point(_geohash), _title)
};
print geohash = 'sv8wzvy7'
| extend url = geohash_to_map_url(geohash, "You are here")
