# Geo Functions

Functions for working with geometric objects, for example [to calculate distances between points on a sphere](/docs/reference/functions/regular-functions/geo/coordinates), [compute geohashes](/docs/reference/functions/regular-functions/geo/geohash), work with [h3 indexes](/docs/reference/functions/regular-functions/geo/h3), and [encode Mapbox Vector Tiles](/docs/reference/functions/regular-functions/geo/mvt).
