Well, that convinces me... *pdf is definitely "better."
I can easily read the name of the town on the map,
Paramaribo in the pdf file, but I would never have been
able to make that out for certain on the same section of
the bmp map. (not to mention, the colors are different)
A pdf file is like vector graphics. You can enlarge
and enlarge, but you don't get that blocky look when you
do.

PDF means Portable Document Format, and was designed
as a way to transfer *documents* meant for printing.
Naturally, in order for such a document to retain a
lot of fine detail, it's going to be a larger file.
File formats all have their trade-offs. PDF gives
great detail at the cost of a littl more size. How
could it be otherwise?
