This exercise creates a surface observsation station plot for the state
of Florida, using both METAR (datatype <em>obs</em>) and Synoptic (datatype
<em>sfcobs</em>). Because we are using the AWIPS Map Database for state and
county boundaries, there is no use of Cartopy <code class="docutils literal notranslate"><span class="pre">cfeature</span></code> in this
