zodiac killer map

Ok, So where Paul Stines stopped was the Presido Hill school that teaches Students in almost every lower school class have weekly excursions in the Presidio where they explore local plants and animals, learn about maps and navigation, and investigate Native American culture. https://www.presidiohill.org/academics/environmental-education

Here the lines from Mt Diablo Initial Point, Dennings memorial.  I haven't noted distance and angle yet.  The Zodiacs bomb located proportionately to the calcs?

Considering Theo was anti development and the Devil mountain is the centralised initial point for cadastral boundaries used to create land allotments for the subdivision in building and destruction of forest land and wildlife, Theo holds a similar theme in The Zodiac philosophy, mathematics, bomb making, geodetic locations. The Zodiac and Theo hold similar themes in their murder with mathematics etc. The choice of location being Devil mountain and its cartography attributes on the Phillips 66 map. In 1967, Kaczynski's dissertation Boundary Functions [29] won the Sumner B. Myers Prize for Michigan's best math dissertation of the year. [8] Like Ted, Zodiac says humans are much more fun to hunt than animals. Mathematics, Bomb making, Cryptography. The taxi was asked to stop at Washington and Maple, but continued onto Cherry.  Denning was part of military intelligence which may add to the theme. Maple are a type of tree Unabomber would not of gladly see be diminishe...

Here is the copper bolt for initial point cadastral boundary centralised reference which is more than likely where the piece of map ripped out by The Zodiac Killer was survey referenced from. Lt Col Norman Edwin Denning was responsible for the Mt Diablo (Devil Mountain) initial point meridian and baseline.  Zodiacs spatial map, Phillips 66 petroleum map would have been created from this initial benchmark point. *Note the symbol of circle and cross aka crux of the initial point in reference Zodiacs ciphers and map denoting set to magnetic north (16.5 to 17 degrees magnetic declination). So, S = (R(map inches) * θ ); Zodiac has symbols through his encryption code

Here we see geodetic survey symbols and reference to radian calculations right through the cipher which suggests the possibility that Zodiac was knowledgeable in cartography. The number of characters between each of the characters could be inches, especially the Zodiac button symbols, often used in geodetic benchmark locators, as the copper bolt within the Mt Diablo Initial Point Meridian Denning monument. Was The Zodiac trained in military cartography?  Someone who was high up in USMC? S = (R(map inches) * θ )

So, on the map, the inches from Mt Diablo, "on the map" in inches to the murder sites references radians around to ??? Next murder? Encryption key? "The Mt. Diablo code concerns Radians & # inches along the radians."  So, S = (R(map inches) * θ ) ; Zodiac has symbols through his encryption code

I have added the 17 degree Magnetic Declination into the map that The Zodiac requested which is something someone with a compass would do for hiking or in a military situation. "The Mt. Diablo code concerns Radians & # inches along the radians."    Zodiac is working in Imperial calculations which may mean the old Degrees, Minutes and Seconds The buttons maybe military and datum's.  Maybe he was a military surveyor or similar that worked for Denning?

Ok, based upon Zodiacs use of the Phillips 66 map, and his placement of the button surveyors symbol over the Dennings Mt Diablo Initial Point, Benchmark: HS5120, I have adjusted the meridian accordingly over the official coordinates of the Mt Diablo Dennings Initial Point Meridian. Other adjustments have to be made according the Zodiacs request.  Dennings history in USMC and Zodiacs skillsets may suggest he has military background, possibly Special Forces etc of the day. Bomb making, Map making, Surveying, Crime scene firearm usage. S = (R(map inches) * θ )

Ok, so it appears there is a difference between coordinates on Coll, Ransom and the current but this can happen.  Maps are amended the places change though the years. This does mean however I will have to upgrade the meridian I have already according Ramsom's  coordinates. Mount Diablo Meridian Most Initial Points are created incidentally, as baselines (and sometimes the meridians) are usually created first, with one end anchored on relatively immutable geographic features, such as the confluence of rivers, or latitudinal lines. The west has a number of exceptions, where prominent peaks were selected to be Initial Points, and then base-lines and meridians were drawn from them, as their visibility from great distances aided the surveyor’s task. Such was the case with Mount Diablo, an isolated mound rising above the surrounding valley, east of the San Fran...

The Diablo Meridian from Initial Point according the Chief Surveyor Ransom Zodiac Killer Meridian Map

The cross and the circle are common symbols in survey, Zodiacs circle cross sits over the Mt Diablo mountain cairn.  It sits on the Diablo meridian and baseline that the Phillips 66 map is derived from. I believe knew the origins of the Devil mountain meridian and baseline that created the map which means he had knowledge of surveying and it's underlying derivatives. Is this one of Zodiacs buttons The Zodiac Killer refers? Do you like my buttons? https://www.pinterest.com.au/sebdav24/surveying/?lp=true

The Zodiac Phillips 66 map has a symbol over Mt Diablo (Spanish for Devil).  Mt Diablo is the datum reference point for the map and the symbol over devil mountain is a surveyors symbol. The whole Phillips petroleum map would have been referenced around this cairn on Mt Diablo as someone with a theodolite could see this reference point from many places. This means Zodiac knows about how the map was made and has knowledge of surveying and how the early map was developed. The symbol on the map is directly referenced over the datum point with request to set the symbol at magnetic north. The symbol is that of a road surveyor or similar.  Are his murders referenced to Devil Mountain datum reference point? These buttons he references are datum points.  Devil mountain is the origin point of how the map was created.  His buttons as he calls them can also be datum studs which are used to place the theodolite staff on.  He may have been a civil engineer or ro...
