Hi All,<br><br>I'm having some problems with features that are being returned from an ST_Buffer operation in PostGIS. When I try to buffer the extents of Papua New Guinea, a large region in the middle of its extents is omitted. You can see a visual representation of this at <a href="http://lagerratrobe.blogspot.com/2009/03/problem-with-postgis-stbuffer.html">http://lagerratrobe.blogspot.com/2009/03/problem-with-postgis-stbuffer.html</a><br>
<br>If I just select the country itself, I get back all of the features that I'm expecting. In the image I've posted above, the black area indicates the results of that query.<br><br>I am using postgresql-8.3.5, and postgis-1.3.3. My select statements is as follows:<br>
select name, Buffer(the_geom, .12) from coastlines where iso_3_code = 'PNG';<br><br>I've tried this using both a free countries shapefile, as well as an ESRI one, and get the same results. I'm a bit baffled, and unsure if I have a problem with both data sets, or in my query, or...? If someone else has had a similar problem in the past, and can shed some light on it, I'd greatly appreciate it.<br>
<br>Thanks in advance,<br><br>Roger<br>--<br>
