I have a layer containing a lot of polygons. In the first zoom stage all features are fine. But if I zoom in: more and more features disappear randomly. While panning some features appear again but others disappear. <br></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica, sans-serif;background-color:transparent;font-style:normal;"><br></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica, sans-serif;background-color:transparent;font-style:normal;">I found some
remarks to that problem:<br></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica, sans-serif;background-color:transparent;font-style:normal;">I read something about 'features with too much vertices disappear' (but not in context of
mapserver) - this is not the reason, because also small polygons disappear while bigger ones are displayed.</div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica, sans-serif;background-color:transparent;font-style:normal;">Another problem is if some points of the polygon are outside of the current map extent. That's also not the case - in my map features in the center disappear, too.</div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica, sans-serif;background-color:transparent;font-style:normal;"><br></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica, sans-serif;background-color:transparent;font-style:normal;">Are there any other suggestions?</div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica, sans-serif;background-color:transparent;font-style:normal;"><br></div><div style="color:rgb(0, 0, 0);font-size:16px;font-family:arial, helvetica,
