Hello all,



I need some help understanding some projection information on an older map of Belgium that my assistant and I are cataloging:



Belgien 1:300000

Verwaltungskarte

Umwandlund der Bonneschen Koordinaten in Lambertsche Koordinaten für die Y-Werte



I understand the concept, but the map itself shows some lines that I don't know how to describe.  A portion of the map is shown in the attached image along with explanatory text.  How would I describe this in the bibliographic record?



Thanks!


Louise
