This contains columns for the Latitude and Longitude (to and from), Depot, Name, Parts value, and Demand. The most common SRID is 4326, which has the information in meters. Without this step, the result is just over 4 million meters (4,014,163 meters). Setup. This is because different initial headings having different initial altitude rules (even alts vs odd alts). The Haversine Formula class listed below is used to calculate the distance between two latitude/longitude points in either Kilometers or Miles. The geography functions operate on or generate BigQuery GEOGRAPHY values. By the way, the constant value 20,890,584 is the earth's average radius in miles (3,956.55) multiplied by 5,280 feet per mile. earthdistance. Using the Code You can calculate geo distance using spatial types - geography datatype in SQL server.
