Columbia Street Stamps
This is the diagram we use to catalog the stamps at each intersection.
The actual stamps are indicated by the handwriting, while the typing is for your information.
With this diagram we can see, on one page, the orientation of all the stamps and their relationship to each other as well as to the street corners.
The sidewalks in the diagram are wide to allow room for writing in the text of the stamps. The streets are narrow because they contain no stamps.
each corner, we also use a picture like this to show the actual look
of the street corner. The black stamp indications are electronically
applied in the approximate locations of the real stamps, which you
will see on the same page.
The compass rose, also, is applied in the computer to show the proper orientation. It is not a stamp.
