I'm interested in finding the relationship between scale factors of LCC maps
(aviation) that are designed so they can be put next to each other and
have a different scale factor each.
The maps cover parts of Europe with standard parallels at 40°N and 52°N. The
scale factor differs slightly and I am interested in a formula to calculate
I have found this in a forum message from 2007:
"Find a chart that gives the true scale at 54ºN and divide that into
This is the scale factor. For 51N the scale factor is 500/515=0.9709, =
Running Hooijberg's algorith for LCC, 2 parallels, the scale factor at
Unfortunately a search for Hooijberg's algorithm was not successful. Any
