Drawing map scales with Basemap

Dear Jeff & ALL,

Are there any examples of the use of the drawmapscale() Basemap
method? I can use this myself and will also add any examples to the
forthcoming "Basemap Cookbook" website (for this, I am compiling all
available examples).

Thanks in advance!

Best wishes,

Dear Jeff,

Thanks.... Unfortunately, the map scale cannot be drawn for
cylindrical projections like the Equirectangular default... :frowning:

Mauro: That's because the default is not really a map projection at all - it just displays the data in lat/lon coordinates. The map scale really has no meaning in that case.

has no meaning in that case.

Sure, however some biological journals insist that authors provide
these scales (and in at least one case I known of, also a wind
rose!!!!) on all maps, even if when they have no meaning (as is the
case with the Equirectangular projection). Regrettably, as I mentioned
earlier, there have been no discussion of map projections -- their
meaning and significance -- among biogeographers.

With best regards,
