 If you want the latitudes and longitudes of the corners of grid cells, x and y coordinates can be incremented by half the grid cells width and height, and the resoluting projected coordinates passed to `transform.transformer`.
 
-It is worth considering if you really need to have latitude and longitude arrays for your dataset.  One reason that CF-conventions were changed, was that 2D arrays of geographic coordinates can increase the file size, especially for high resolution datasets.  Projected coordinates as vectors take up much less space.  Plotting tools such as `cartopy` can make maps without latitude and longitude.  If you need to extract cell values for specific geographic coordinates, for example for a weather station or buoy, it is quicker and easier to transform these coordinates into the projected coordinate system of the dataset.  The `xarray.Dataset.sel` or `xarray.DataArray.sel` methods can then be used to select the data for that location.
