<h1>Geospatial Data</h1>

<h2>Geocoding</h2>
<p class="flow-text">
Geocoding refers to the process of converting a description of a location into position coordinates on the surface of the earth (latitude and
longitude). This process is very in demand if you need to get the coordinates of the location to use it later for further aggregation by geo-referenced
data in the database. Or if you simply need to show place on the map.
</p>
<p class="flow-text">
To get coordinates for specific place you can use the <span class="hlt2">geocode</span> command:
