Consider $P_1(a, b)$ and $P_2(c, d)$ to be two points on a 2D plane.
LAT_N in STATION).LONG_W in STATION).LAT_N in STATION).LONG_W in STATION).Query the Manhattan Distance between points $P_1$ and $P_2$ and round it to a scale of 4 decimal places.
The STATION table is described as follows:
where LAT_N is the northern latitude and LONG_W is the western longitude.
