# Geostationary Projection

The geostationary projection displays the earth as a satellite (in geostationary orbit) would see it.

    from mpl_toolkits.basemap import Basemap
    import numpy as np
    import matplotlib.pyplot as plt
    # lon_0 is the central longitude of the projection.
    # resolution = 'l' means use low resolution coastlines.
    # optional parameter 'satellite_height' may be used to
    # specify height of orbit above earth (default 35,786 km).
    m = Basemap(projection='geos',lon_0=-105,resolution='l',rsphere=(6378137.00,6356752.3142))
    m.drawcoastlines()
    m.fillcontinents(color='coral',lake_color='aqua')
    # draw parallels and meridians.
    m.drawparallels(np.arange(-90.,120.,30.))
    m.drawmeridians(np.arange(0.,420.,60.))
    m.drawmapboundary(fill_color='aqua')
    plt.title("Full Disk Geostationary Projection")
    plt.show()
