Howdy,
This is my first post to geoserver-users. I have been using geoserver for about a year now, and have had a lot of success. I have run into a problem with tiling artifacts in a WMS layer displayed OpenLayers.
I am enclosing an image that shows the problem to see if anyone has run into a similar problem and has any useful suggestions. I realize I am not going to give enough data to reproduce the problem since the application stack is so large.
I am using a Django website to run a python script that uploads a shapefile and using the gdal bindings to create data in a postgis data store which Geoserver serves up. If I use Geoserver to directly render the shapefile, it appears normal. The artifacts are not there. It is only after using the Django ORM that the tiling artifacts appear. The data in the database looks correct, and I go through a WKT step in the middle where I can look at the data and I swear it looks correct. The artifacts are on tiling boundaries. If I change the map zoon the location and number of artifacts changes and still are on tile boundaries. It feels like something about my data is causing the geoserver tiling algorithm to in introduce the artifacts, but for the life of me, I can’t think of what it would be.
If anyone thinks of anything else I can post to help, please make suggestions.
