mapset

cfplot.mapset(lonmin=None, lonmax=None, latmin=None, latmax=None, proj='cyl', boundinglat=0, lon_0=0, lat_0=40, resolution='110m', user_mapset=1, aspect=None)

Sets the mapping parameters.

lonmin=lonmin - minimum longitude

lonmax=lonmax - maximum longitude

latmin=latmin - minimum latitude

latmax=latmax - maximum latitude

proj=proj - 'cyl' for cylindrical projection. 'npstere' or 'spstere'

for northern hemisphere or southern hemisphere polar stereographic.

ortho, merc, moll, robin and lcc are abreviations for orthographic,

mercator, mollweide, robinson and lambert conformal projections

'rotated' for contour plots on the native rotated grid.

boundinglat=boundinglat - edge of the viewable latitudes in a

stereographic plot

lon_0=0 - longitude centre of desired map domain in polar

stereographic and orthogrphic plots

lat_0=40 - latitude centre of desired map domain in orthogrphic plots

resolution='110m' - the map resolution - can be one of '110m',

'50m' or '10m'. '50m' means 1:50,000,000 and not 50 metre.

user_mapset=user_mapset - variable to indicate whether a user call

to mapset has been made.

The default map plotting projection is the cyclindrical equidistant

projection from -180 to 180 in longitude and -90 to 90 in latitude.

To change the map view in this projection to over the United Kingdom,

for example, you would use

mapset(lonmin=-6, lonmax=3, latmin=50, latmax=60)

or

mapset(-6, 3, 50, 60)

The limits are -360 to 720 in longitude so to look at the equatorial

Pacific you could use

mapset(lonmin=90, lonmax=300, latmin=-30, latmax=30)

or

mapset(lonmin=-270, lonmax=-60, latmin=-30, latmax=30)

The default setting for the cylindrical projection is for 1 degree of

longitude to have the same size as one degree of latitude. When plotting

a smaller map setting aspect='auto' turns this off and the map fills the

plot area. Setting aspect to a number a circle will be stretched such

that the height is num times the width. aspect=1 is the same as

aspect='equal'.

The proj parameter accepts 'npstere' and 'spstere' for northern

hemisphere or southern hemisphere polar stereographic projections.

In addition to these the boundinglat parameter sets the edge of the

viewable latitudes and lon_0 sets the centre of desired map domain.

Map settings are persistent until a new call to mapset is made. To

reset to the default map settings use mapset().

Returns:

None
