Proper Terms For Representing GPS Coordinates


In [another
question](https://japanese.stackexchange.com/questions/4606/sokuon-diacritic-
and-wabun-morse-code), I mentioned using Kana to represent the GPS coordinates
for:

[code]

    N 43° 09.725' W 077° 26.688' 
    
[/code]

I used:

[code]

    キタ シジュウ サン ジスウ ク チョボ ナナヒャク ニジュウ ゴ フン
    kita shijuu san jisuu ku chobo nanahyaku nijuu go fun
    
    ニシ ナナジュウ シチ ジスウ ニジュウ ロコ チョボ ロッピャク キュウジュウ ハチ フン
    nishi nanajuu shichi jisuu nijuu roku chobo roppyaku kyuujuu hachi fun
    
[/code]

Are the terms that I used for north, west, degree, decimal, and minutes
correct in the context that I'm using them?

  * north | kita | キタ
  * west | nishi | ニシ 
  * degrees | jisuu | ジスウ
  * decimal | chobo | チョボ
  * minutes | fun | フン




`次数` (jisuu) seems to be "degree" in the [graph
theory](https://en.wikipedia.org/wiki/Degree_%28graph_theory%29) sense, not as
in angles. I've never heard `ちょぼ` used for "decimal point", but perhaps I'm
ignorant here.

The terms I would use are `度` (do) and `点` (ten) respectively. `コンマ` (comma)
is also heard as a decimal point separator (even when the symbol `,` is not
used).

Note that, as in English, numbers after a decimal point should be spelled out
individually, not using a place system:

English: `.688` is read e.g. `point six eight eight` not `point six hundred
and eighty eight`.  
Japanese: `.688` is read e.g. `てん ろく はち はち` not `てん ろっぴゃく はちじゅう はち`.
