[GRASSLIST:2380] scan-resolution for maps

[E. Koster]

Dear grass-list,
I remember from several years ago (grass4.x) there was a document from Cerl 
talking about resolution and accuracy of maps. This article took the minimal 
line-width on a map, and calculated, based on the map-scale which resolution 
was best to scan the map.
In my files I cannot find the document I mentioned, and since I do not know 
the title a search on the web is nearly impossible.
Probably some of you will know what text I am refering to. Could you please 
send me a reference, or introduce me to any other literature on this 
subject?

the map I want to scan was created in 1639 using a copper-plate. The 
instrument used to engrave can make lines up to a 0.1 mm in width. The 
resolution of the map is 1:2.400. At what resolution I should scan not to 
have an overkill of information?

thank you in advance for your help,
Elwin Koster
