title: Cannot display latitude and longitude nor coastlines using cartopy
body: <p>I am working with GOES-16 satellite imagery which come in netcdf files. I want to crop the file so that it only shows Puerto Rico and the outline. I can get it to crop, but latitude and longitude won't show up, neither will the coastline of Puerto Rico. Below is my sample code.</p>
  <pre><code>import netCDF4 as nc
  from netCDF4 import Dataset
  import cartopy as ccrs
  import cartopy.mpl.ticker as cticker
  import matplotlib
  import matplotlib.pyplot as plt
  import matplotlib.ticker as mticker
  #from mpl_toolkits.basemap import Basemap 
  import metpy
  import numpy as np
  import cv2
  from cv2 import remap
  import xarray
  
  fn = 'OR_ABI-L2-ACMC-M6_G16_s20211730001172_e20211730003545_c20211730004314.nc'
  
  ds = xarray.open_dataset(fn)
  nc = nc.Dataset(fn)
  
  variable = 'BCM'
  bcm = ds['BCM'][:].data
  
  bcm = np.clip(bcm, 0, 1)
  
  geo_extent = nc.variables['geospatial_lat_lon_extent']
  print(geo_extent)
  #set latitude and longitude values from metadata
  
  min_lon = float(geo_extent.geospatial_westbound_longitude)
  max_lon = float(geo_extent.geospatial_eastbound_longitude)
  min_lat = float(geo_extent.geospatial_southbound_latitude)
  max_lat = float(geo_extent.geospatial_northbound_latitude)
  
  dat = ds.metpy.parse_cf('BCM')
  
  geos = dat.metpy.cartopy_crs
  x = dat.x
  y = dat.y
  print(x.min())
  
  fig = plt.figure(figsize=(12, 15))
  
  
  ax = fig.add_subplot(1, 1, 1, projection=geos)
  ax.set_extent([-68.07, -64.65, 16.7, 19.79], crs=geos)
  
  ax.imshow(bcm, origin='upper', extent=(min_lon, max_lon, min_lat, max_lat), transform=geos)
  
  ax.coastlines(resolution='10m', color='black', linewidth=1)
  ax.add_feature(ccrs.cartopy.feature.COASTLINE)
  
  plt.title('Puerto Rico', loc='left', fontweight='bold', fontsize=15)
  
  plt.show()
