These zones use the Lambert conformal conic projection, because it is good at maintaining accuracy along an east west axis, due to the projection cone intersecting the earth's surface along two lines of latitude.

Maps that use other projections, such as Module : Location map / data / USA, which uses an equidistant conic projection . require formulas which are used to calculate the x and y coordinates for the location mark.

The "'Albers equal-area conic projection "', or "'Albers projection "'( named after Heinrich C . Albers ), is a equal area map projection that uses two standard parallels.
14.
The "'American Polyconic projection "'is a map projection conceptualized as " rolling " a separate cone tangent to the Earth at each parallel of latitude, rather than a single cone as in a normal conic projection.

I can handle the creation of the location map module ( I haven't dealt with conic projection, which I think I can ignore on the Northeast map, I will have to figure it out or get some handholding on the other two.
