<br clear="all">Hi All, i'm a newbie with postgis and probably this is an easy question.<br><br>As I know "&&" operator which is used for checking 1 geometry is overlap on another or not.<br>Could I check 1 point is overlap on 1 polygon by the query bellow ?<br>
<pre style="color: rgb(51, 0, 153);"><font size="4"><code>SELECT f.point_id, s.zip_id<br>FROM points f, zips s <br>WHERE ST_SetSRID(ST_MakePoint(f.longitude, f.latitude),4326) && s.zip_polygon;<br></code></font><br>
<font style="color: rgb(0, 153, 0);" size="4">Does anything wrong here? Or could you give me other ways to check 1 point is within in 1 polygon or not?</font><br></pre>Cheers.<br>-- <br>Liem Nguyen<br>Developer<br>Axon Active Corp.<br>
