unable to give latitude and longitude to the basemap
haritha1022 opened this issue · comments
I was trying to plot argoflots data they are situated at same latitude and longitude with little variation i want know exact location of each argofloat
here is the code:
df = pd.read_csv("Book122.csv")
plt.figure(figsize=((19,10)))
x=df['longitude']
y=df['latitude']
m = Basemap(projection='cyl',llcrnrlat=27.1022,urcrnrlat=27.1025,
llcrnrlon=64.7793,urcrnrlon=64.7799,resolution='h')
m.scatter(x,y,zorder=10)
m.drawparallels(np.arange(int(27.101),int(27.103),0.001),labels=[1,0,0,0])
m.drawmeridians(np.arange(int(64.7791),int(64.7798),0.0001),labels=[0,0,0,1])
#m.drawcoastlines()
m.fillcontinents(color='white')
m.drawmapboundary()
plt.show()
The problem is that
int(64.7791) == int(64.7798) == 64
same thing for longitudes. So your np.arange
returns an empty array.
In [2]: np.arange(int(64.7791),int(64.7798),0.0001)
Out[2]: array([], dtype=float64)
This looks more like a support problem and not a bug in basemap
. Since @guziy identified and described the problem in the code snippet, I think we can close this issue.
