<div class="textblock"><p>Creates an areal geometry formed by the constituent linework of given geometry. </p>
<p>The return type can be a Polygon or MultiPolygon, depending on input. If the input lineworks do not form polygons NULL is returned. The inputs can be LINESTRINGS, MULTILINESTRINGS, POLYGONS, MULTIPOLYGONS, and GeometryCollections.</p>
<p>This algorithm will assume all inner geometries represent holes</p>
<p>This is the equivalent of the PostGIS ST_BuildArea() function. </p>
