<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m looking for a way to get all individual polygon extents from a shapefile. I’m currently using FWTools 2.4.7 ogrinfo.exe<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But I really need just the extents. I could take some time to build something to calculate that but I’m hoping I won’t have to. If ogrinfo does not do this, is there a tool that can generate extents for each polygon?<o:p></o:p></p>
