The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/10/earthdistance.html Description:
Hi, I have installed CREATE EXTENSION CUBE; CREATE EXTENSION earthdistance; Post which I ran the following query: SELECT (POINT (19.974, 72.756)<@> POINT (19.195, 72.959)) AS DISTANCE; The answer came back as 21.17534 miles whereas the actual distance (as crow flies) is 55.42 miles which I have checked from 2-3 websites. (Google maps gives a greater distance which is travel by road & this value has been ignored). I know both the places and the distance between both of them cannot be 22 miles. It has to be in excess of 50 miles atleast. What am I missing?
