The SQL query uses the MIN and MAX functions to find the smallest and largest latitude (LAT_N) and longitude (LONG_W) values in the 'STATION' table. It then subtracts the minimum from the maximum for both latitude and longitude, takes the absolute value of these differences, and adds them together. The result is rounded to four decimal places using the ROUND function.
select Round(ABS(MIN(LAT_N) - MAX(LAT_N)) + ABS(MIN(LONG_W) - MAX(LONG_W)),4)
FROM STATION;
