Thanks for the patch. And apparantly you were right until now;-) In any case I would guess that at some point basemap would need to be changed. In shelf sea modelling we are now making setups with horizontal resolutions of down to the order of hundreds of meters and global ocean models are not far from this resolution either: https://www.navo.navy.mil/nipr_2006/modeling.html I am not entirely up to date with meteorological models but at least I know of one limited area model that I use which has a resolution of 5 km. > This will make drawing of meridians and parallels slower, however. What about making the resolution dependent on the size of the map if this is a problem? I have a small method that I am using for creating nice contour levels - although smarter methods definitely must exist. I have tried to adapt it for producing what you need. If you decide to include something like this please be aware that the Decimal(str(delta)) should probably be changed (I don't think it will handle all cases well). Maybe it is faster simply to increase the resolution as you have already done when it becomes necessary: def _getInterval(minval, maxval, ninter): """Returns list which resolves minval to maxval with at least ninter intervals.""" import decimal import numpy as npy # Calculate interval between increments delta = (maxval-minval)/ninter n = decimal.Decimal(str(delta)).adjusted() delta = 10**n # Round off minimum and maximum values xmin = minval/10**n xmax = maxval/10**n xmin = (xmin - xmin % 10)*10**n xmax = (xmax + xmax % 10)*10**n values = npy.arange(xmin, xmax+delta, delta) return values ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
