<p class=MsoNormal>Hi.<o:p></o:p></p>

<div>
<p class=MsoNormal>I have been searching for a way to join raster values to
polygons.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>In my case there is only one raster value within each
polygon, and I would like this value to be joined into a column in the polygon
table.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The process would in other GIS programs probably look like
this:<o:p></o:p></p>

<div>
<p class=MsoNormal>Raster Data -> Point Features -> Spatial Join to
Polygons (with raster value as new column for each polygon).<o:p></o:p></p>
</div>

<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>Any ideas how one would formulate this?<o:p></o:p></p>
