"Near Landmark" series is a series of caches placed close to the landmark.
[ATTENTION]
There is no cache in this coordinates.
The position of coordinates is a Suwa lake.
The Suwa lake was known for a long time as scenic sites.
(Suwa lake of Edo period)
The ”Crest of Paper Mulberry" is often seen in this region.
It is because this local monarch and Suwa family assumed the crest.
(Crest of Paper Mulberry)
This series is cache connected to Crest of Paper Mulberry.
[Method of calculating coordinates] :
(1) It all goes all to four places of "Near Landmark #1 - #4", it writes in the container, and "Keycode" is confirmed.
(2) Coordinates of cache "Near Landmark Final" are calculated by using "Keycode".
"Keycode" of "Near Landmark #1" is defined as A.
The place of ten of A is defined as Aa.
The place of one of A is defined as Ab.
"Keycode" of "Near Landmark #2" is defined as B.
The place of ten of B is defined as Ba.
The place of one of B is defined as Bb.
"Keycode" of "Near Landmark #3" is defined as C.
The place of ten of C is defined as Ca.
The place of one of C is defined as Cb.
"Keycode" of "Near Landmark #4" is defined as D.
The place of ten of D is defined as Da.
The place of one of D is defined as Db.
(Last Cache Coordinates)
N 3x° 0x.xxx
E 13x° 0x.x0x
...x is a figure of one digit.
N 3[Ab-Aa]° 0[Cb].[Ba-Cb][Ca-Ba][Db+1]
E 13[Bb+Cb]° 0[Bb].[Da-Cb]0[Db-1]
(ex.)
"N 3[Ab-Aa]° "
-> A= Near Landmark #1's Keycode, Aa is the place of ten of A & Ab is the place of one of A.
-> If A=12, Aa=1 & Ab=2.
-> N 3[Ab-Aa]° = N 3(2 - 1)° = N 31°
