   MySQL provides functions to perform various operations on spatial
    data. These functions can be grouped into several major categories
    according to the type of operation they perform:
  </p>
  <div class="itemizedlist">
   <ul class="itemizedlist" style="list-style-type: disc; ">
    <li class="listitem">
     <p>
      Functions that create geometries in various formats (WKT, WKB,
        internal)
     </p>
    </li>
    <li class="listitem">
     <p>
      Functions that convert geometries between formats
     </p>
    </li>
    <li class="listitem">
     <p>
      Functions that access qualitative or quantitative properties of
        a geometry
     </p>
    </li>
    <li class="listitem">
     <p>
      Functions that describe relations between two geometries
     </p>
    </li>
    <li class="listitem">
     <p>
      Functions that create new geometries from existing ones
     </p>
    </li>
   </ul>
  </div>
