horse and rider grid 'enhanced' graphic

So, this is a photoshop enhanced graphic, on the hand-drawn original as shown in the previous post. The penta system is in purple, the grid in green. There is one yellow line representing the orientation of the Mavisbank hexagonal system, with Newtongrange Church defining the radius. The rest of the hexagon is omitted, for now.

There are a few light blue lines, which link some features and points of interest, including line of sight points, which would have aided in setting out and surveying.

The horse and rider feature is sketched in on the original, and I have left this be, as that is as artistic as I wish to get, for now.

This has labels attached, and constitute the main points, necessary for defining the geometry and notable features of the figure.

Key points:

A; Allermuir Hill
AS; Arthurs Seat
B; Borthwick Churh
BH; Black Hill
C; Carberry Tower/Queen Margaret's Mount
CK; Currie Kirk
CR; Camp Ridge
G; Galachlaw
L; Leith
M; Mavisbank Earthmound
May; Maybury/Gogar
MH; Mauldslie Hill
MOW; Meeting of the Waters in Dalkeith Park
NA; Newbattle Abbey
NC; Newtongrange Church
P; Penicuik, Sir John Clerk's Estate and House touches this point, and lies to the south.
PUC; Preston Cross(with unicorn on top)
RC; Roslin Chapel
S; Shewington Farm
St.MC; St. Mary's Chapel/Mount Lothian
St.MF; St. Margaret's Toll Farm
TH; Todhills Farm
T; Temple Kirk

First. The sale of the figure is defined by the side of the pentagon(MOW - S) plus an 18 degree segment which is 1.30902 times 6.0678 miles which equals 7.943 miles, which is just short of 8 miles.

Second. The central axis of the figure is defined by this same penta side, and is 31+/- degrees to O.S.grid, the Roseline shown, and true north.
