[mapserver-users] geometries disappear while zooming (leene)

[Mark Volz]

Leene,

It could be that you updated a shapefile without updating the spatial index.   Check your data folder and look for a qix file with the same name as your shapefile.  If the date is older than your shapefile you will either need to delete it, or update it using shptree http://mapserver.org/utilities/shptree.html.

> Hey,
> i'm using Mapserver 6.0.2. 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.
> 
> 
> I found some remarks to that problem:
> 
> 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.
> 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.
> 
> Are there any other suggestions?
