It is a surprisingly difficult problem to calculate an accurate distance between two points on the Earth, both because of the spherical geometry and the uneven shape of the ground.
Fortunately Snowflake has robust support for geographical primitives - the
ST_DISTANCE function can calculate the distance in metres between two
with points as ( -- Longitudes and latitudes are in degrees select 10 as from_long, 12 as from_lat, 15 as to_long, 17 as to_lat ) select st_distance( st_makepoint(from_long, from_lat), st_makepoint(to_long, to_lat) ) as dist_in_metres from points
