Fred,<br>The problem with large polygons like this is that loading a small<br>section like you're doing still requires the entire polygon to be processed.<br>One solution is to break the polygon into tiles closer to the size you
<br>intend to display. This way the indexes can be used more effectively,<br>and only the areas you're displaying needs to be processed.<br>Mark<br><br>Frederico Lucca wrote:<br>> Hello list,<br>><br>> I have a layer with a single polygon, but it has 131570 points. It's the
