The corner point of the square (a

) and the length of its sides is given in
degrees. Note that these values are rounded to degrees, and due to the
requirement that the square shall include the entire circle; this will result in a
slightly larger area than defined by the user input.
Attention when close to the poles: If the latitude of the corner point ‘a’ is
transformed to a value greater that 90° then it is set to 90° and the length
b
is reduced correspondingly. If the length
a is greater than 90° then
a is set
to 90°.
