Hi Lime,<div><br></div><div>I cannot release the shapes (I am sure that you understand) but I can tell you how I've created them. Using gdal_polygonize.py on a raster big as UK with only 2 colors: 0,1. Each pixel is a 5x5 meters squares. The Image displays the UK water surface. The bigger polygons belong to the coast.</div>

<p class="MsoNormal">Hi All,</p>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I have a shape with 2M polygons. The biggest one has 13k
points. It works very well, and fast enough.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I have another shape with 300k polygons and the biggest one
has 800k points... This shape hangs MapServer !... and I have to kill the process
by hand using kill -9. (see the other thread: process survive after killing
apache). The shape files can be opened with ogrinfo though</p>

<div>
<p class="MsoNormal">Is there a maximum number of points for single polygon
supported by MapServer ?</p>
