Basemap Problems

Hello,

I am currently working with Basemap to plot a shapefile on the map. However, I am confused on how to initialize llcrnrx and llcrnry and same for the upper corner. I currently have both latitudes and longitudes for lower and upper corners in degrees. Does this
mean I have to convert from degrees to x,y coordinates? I tried using llcrnrlon and llcrnrlat but it doesn’t seem to like this. Please help me clarify this, any help would be great.

Thank You

Edgar,

You feed lat/lon (float) values. See this example here:

http://matplotlib.org/basemap/users/cea.html

And a whole collection of setting up maps in other projection here:

You also need to make sure that all of inputs make sense together (e.g., you’re not specifying any corners beyond the range of your specific projection)

By the way, if you want quick-n-easy plotting of shapefiles, I suggest using GeoPandas, which makes it dead simple.
