<div>
<p class=MsoNormal>Hi All,<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Intersection problem:<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I have an application performs a query on a polygon layer
with a point - using intersection with the spatialfilter.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The problem is this:<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The polygon originated from a shapefile - loaded as SDF via
studio.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The single polygon feature originally was 2 distinct
polygons dissolved together via ArcMap.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The intersection works only on one of the polygons, and
fails to return a feature reader at all when within the other polygon.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>This fails in both code execution and as a GeFeatureInfo WMS
request in the same manner.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Has anyone encountered this?<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Has anyone worked around?<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Is it better to explode the feature? I require the
geometery from each part to do a highlight.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Is there an issue with how a shapefile multipolygon is
converted to SDF?<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Or is this an isse with the SelectFeatures functionality?<o:p></o:p></p>
