This puzzle requires a little bit of special (but not specialist) knowledge. Having said that, once you've worked out how to solve the puzzle, it is very very straightforward.
Step 1: work out the missing words from this list.
- architecture
- b-----
- communication
- distinct
- escape
- flora
- gastronomy
- h-----
- institution
- january
- key
- l-----
- mate
- notorious
- o-----
- pioneer
- q-----
- r-----
- s-----
- t-----

Step 2: take the following letters:
0. the first letter of the word beginning with B
1. the third letter of the word beginning with H
2. the fourth letter of the word beginning with L
3. the second letter of the word beginning with O
4. the fifth letter of the word beginning with Q
5. the third letter of the word beginning with R
6. the sixth letter of the word beginning with S
7. the fourth letter of the word beginning with T
8. the third letter of the word beginning with W
9. the fourth letter of the word beginning with Z
Step 3: arrange the letters into two five-letter strings, in the following order: 63287 91054
Step 4: translate all the letters to numbers using A B C = 1 2 3 (with O = 0). Add decimal points between the second and third numbers of each string.
You should now have two strings of five digits each. Add 00002 to the first string. The first string is to be appended to S 37°, the second to E 145°. These are your real coordinates. If you're unsure, GeoCheck your coordinates. Good luck!
