I have a 1965 raised relief map of California I use to estimate fireball
explosion positions. It is a Nystrom "Lambert Conformal Conic Projection" 1:
1,000,000.
My question is how close are the Longitude lines in (alignment) to TRUE
NORTH ?
Latitude or elevation is not an issue. Thank you.
(I have had varying answers from Nystrom, who suggested aligning the map(?)
with a compass, then rotate the map CCW 16 degrees ). There are no magnetic
declination reference marks on this map. Just latitude and longitude.
