 ## Geographic data packages {#sec-geographic-data-packages}
 
-To complete...
+Many Python packages have been developed for accessing geographic data, some of which are presented in @tbl-data-packages. 
+These provide interfaces to one or more spatial libraries or geoportals and aim to make data access even quicker from the command line.
+
+| Package | Description |
+|---|-----------|
+| `cartopy` | Download layers from [Natural Earth Data](https://www.naturalearthdata.com/downloads/) | 
+| `...` | ... | 
+| `...` | ... | 
+| `...` | ... | 
+: Selected Python packages for geographic data retrieval {#tbl-data-packages}
+
+Each data package has its own syntax for accessing data. 
+This diversity is demonstrated in the subsequent code chunks, which show how to get data using three packages from @tbl-data-packages. 
+Country borders are often useful and these can be accessed with the ne_countries() function from the rnaturalearth package as follows:
+
+```{python}
+import cartopy
+filename = cartopy.io.shapereader.natural_earth(
+ resolution='10m',
+ category='cultural',
+ name='admin_2_counties'
+)
+counties = gpd.read_file(filename)
+counties
+```
+
+```{python}
+counties.plot();
+```
