    • Manhattan Distance in a plane with p1 at (x1, y1) and p2 at (x2, y2) is |x1 - x2| + |y1 - y2|
    • Here it's ABS(a - c) + ABS(b - d)
    • a = MIN(LAT_N), b = MIN(LONG_W), c = MAX(LAT_N), d = MAX(LONG_W)
    SELECT 
ROUND(ABS(MIN(LAT_N) - MAX(LAT_N)) + ABS(MIN(LONG_W) - MAX(LONG_W)),4)
FROM STATION
