Advantages of latitude and longitude
- Integrate with google map or any map related service to show exact place of the city in the map.
- Find locations are within a certain radius distance of a given latitude/longitude.
Here's the SQL statement that will find the closest locations that are within a radius of 25 kilometers to the 7.358849, 81.280133 coordinate. It calculates the distance based on the latitude/longitude of that row and the target latitude/longitude, and then asks for only rows where the distance value is less than 25, orders the whole query by distance.
SELECT id, name_en, name_si, name_ta, (6371 * ACOS(COS(RADIANS(7.358849)) * COS(RADIANS(latitude)) * COS(RADIANS(longitude) - RADIANS(81.280133)) + SIN(RADIANS(7.358849)) * SIN(RADIANS(latitude)))) AS distance
FROM cities
HAVING distance < 25
ORDER BY distance- This free database dose not guarantee for the complete list of cities in Sri Lanka.
