(center_ll=None, extent=None, ny=600, nx=None, origin='lower-left', transverse=True)[source]¶ Local (transverse) mercator map centered on a specified point.
Parameters: - center_ll : (float, float)
tuple of lon, lat coordinates where the map will be centered.
- extent : (float, float)
tuple of eastings, northings giving the extent (in m) of the map
- ny : int
number of y grid points wanted to cover the map (default: 600)
- nx : int
number of x grid points wanted to cover the map (mutually exclusive with y)
- origin : str
‘lower-left’ or ‘upper-left’
- transverse : bool
wether to use a transverse or regular mercator. Default should have been false, but for backwards compatibility reasons we keep it to True
