Consider and to be two points on a 2D plane.

happens to equal the minimum value in Northern Latitude (LAT_N in STATION). happens to equal the minimum value in Western Longitude (LONG_W in STATION). happens to equal the maximum value in Northern Latitude (LAT_N in STATION). happens to equal the maximum value in Western Longitude (LONG_W in STATION). Query the Manhattan Distance between points and and round it to a scale of decimal places.

The Manhattan Distance formula for two points (x1, y1) and (x2, y2) is: DManhattan = (x1−x2) + (y1−y2)

Applying this to points P1(a, b) and P2(c, d): DManhattan=(a−c) + (b−d)

N.B ABS() (absolute value) function, is crucial for Manhattan distance.

select round((max(long_w)-min(long_w))+(max(lat_n)-min(lat_n)),4) from station;
