<h4>Requirements</h4>
</a>
To view a delimited text file as layer, the text file must contain:
<ol>
<li>A delimited header row of field names. This must be the first line in the text file.</li>
<li>The header row must contain an X and Y field <em>or</em> a Well Known Text (WKT) field. These fields can have any name.</li>
<li>The <B>x</B> and <B>y</B> coordinates must be specified as a number. The coordinate system is not important.</li>
<li>A WKT field must be in the standard format.
</ol>

<h4>Notes</h4>
</a>
<ol>
  <li>The example text file:</li>
<ul>
<li> Uses <b>;</b> as delimiter. Any character can be used to delimit the fields.</li>
<li>The first row is the header row. It contains the fields X, Y and ELEV.</li>
<li>No quotes (") are used to delimit text fields.</li>
<li>The x coordinates are contained in the X field.</li>
<li>The y coordinates are contained in the Y field.</li>
</ul>
<li>The example text file with WKT:</li>
<ul>
  <li>Has two fields defined in the header row: id and wkt.
  <li>Uses <b>|</b> as a delimiter.</li>
  <li>Specifies each point using the WKT notation
</ul>
</ol>
