I'm trying what I thought was a simple test and getting "bad" results. I am
taking some lat long coords, and feeding it into a map. The conversion is
not giving "real" values that can be plotted on a map (and actually produces
an error when I use annotate).
I'm including the simple code and the output:
>>>>>>>>>CODE<<<<<<<<<<<<<<<
import pylab as p
import numpy
from matplotlib.toolkits.basemap import Basemap as Basemap
from matplotlib.colors import rgb2hex
from matplotlib.patches import Polygon
# Lambert Conformal map of lower 48 states.
# create new figure
fig=p.figure()
m1 = Basemap(llcrnrlon=-119,llcrnrlat=22,urcrnrlon=-64,urcrnrlat=49,\
projection='ortho',lat_1=33,lat_2=45,lon_0=-95,lat_0=40,resolution='c')
#COS
#D + M/60 + S/3600
COSLat=38+56.0/60.0+0.013
COSLon=-1*(104+48.0/60.0)
WASHLat=38+53.0/60.0+23.0/3600.0
WASHLon=-1*(77+32.0/3600.0)
print COSLat
x, y = m1(COSLat,COSLon)
print 'x =%f, y=%f' % (x,y)
m1.plot([x],[y],'ko')
ax=p.gca()
ax.annotate('COS1',(COSLat,COSLon))
#ax.annotate('COS2',(x,y))
ax.annotate('Wash1',(WASHLat,WASHLon))
x, y = m1(WASHLat,WASHLon)
#ax.annotate('Wash2',(x,y))
m1.drawcoastlines()
m1.fillcontinents()
m1.drawcountries()
m1.drawstates()
m1.drawparallels(numpy.arange(25,65,4),labels=[1,0,0,0])
m1.drawmeridians(numpy.arange(-120,-40,4),labels=[0,0,0,1])
p.title('full resolution')
p.show()
