Sure, but you'll need to know your Latitude and Longitude first
though, to the requisite resolution...
1. Determine which Longitude band you fall in, from the following
list, noting that the measurements are West or East of the
Greenwich Meridian, and note the relevant letter down as being
the first character in your Maidenhead locator:
180-160 West - Use A 160-180 East - Use R
160-140 West - Use B 140-160 East - Use Q
140-120 West - Use C 120-140 East - Use P
120-100 West - Use D 100-120 East - Use O
100-80 West - Use E 80-100 East - Use N
80-60 West - Use F 60-80 East - Use M
60-40 West - Use G 40-60 East - Use L
40-20 West - Use H 20-40 East - Use K
20-0 West - Use I 0-20 East - Use J
2. Determine which Latitude band you fall in, from the following
list, and note the relevant letter down as being the second
character in your Maidenhead locator:
90-80 South - Use A 80-90 North - Use R
80-70 South - Use B 70-80 North - Use Q
70-60 South - Use C 60-70 North - Use P
60-50 South - Use D 50-60 North - Use O
50-40 South - Use E 40-50 North - Use N
40-30 South - Use F 30-40 North - Use M
30-20 South - Use G 20-30 North - Use L
20-10 South - Use H 10-20 North - Use K
10-0 South - Use I 0-10 North - Use J
3. If you are located West of Greenwich, subtract your Longitude
Degrees (ignoring Minutes and Seconds) from the high end of the
band you determined it to be part of in part 1, calling this E.
If you are East of Greenwich, subtract the low end of the band
you determined in part 1 from your Longitude and call that E.
Divide E by 2, noting the whole number part as being the third
character of your Maidenhead locator.
4. If you are located South of the Equator, subtract your Latitude
Degrees (ignoring Minutes and Seconds) from the high end of the
band you determined it to be part of in part 2, calling this N.
If you are North of the Equator, subtract the low end of the band
you determined in part 2 from your Latitude and call that N.
Note down N as being the fourth character of your Maidenhead
locator.
5. If the value E determined in step 3 was an odd number, add 60 to
your Longitude Minutes, otherwise use your Longitude Minutes as
given. In either case, divide the relevant number by 5, ignoring
any fractional value, and look it up in the table below, noting
the associated character as being the fifth character of your
Maidenhead Locator.
6. Take the number of Latitude minutes and double them. If your
Latitude seconds are 30 or greater, add 1 to the result, else
leave it as is. In either case, divide the result by 5, ignoring
any fractional value, and look it up in the table below, noting
the associated character as being the sixth character of your
Maidenhead Locator.
0 = A 6 = G 12 = M 18 = S
1 = B 7 = H 13 = N 19 = T
2 = C 8 = I 14 = O 20 = U
3 = D 9 = J 15 = P 21 = V
4 = E 10 = K 16 = Q 22 = W
5 = F 11 = L 17 = R 23 = X
Note that there are two exceptions to this scheme:
1. The South Pole is defined as being that point located at Latitude
90 South and, by the definition of Latitude and Longitude, always
occupies all Longitude values. It is usual to refer to the South
Pole as having the Maidenhead locator AA00AA.
2. The North Pole is defined as being that point located at Latitude
90 North and, by the definition of Latitude and Longitude, always
occupies all Longitude values. In addition, the band labelled as
R in part 1 strictly does not include 90 North, and it is thus
correct to refer to the North Pole as having Maidenhead locator
SA00AA.
Hopefully this helps...
Best wishes from Riley.
