[OpenLayers-Users] Vector disappears when zooming in (sometimes)

[Tommy74]

Hi!

Thanks for you answer Andreas!

What does "renderer runs out of coordinate space" really mean? Is there a limitation in OpenLayers/VML or is this a common GIS-"feature"? Can it be fixed or is it possible to do a simple workaround?

The vector data is not a static file, but is created as GeoJSON on the server in my real application, but that's a custom geojson generator, not a WFS or FeatureServer. Unfortunately there is no time to change the type of datasource at the moment. The goal is to serve the data from WMS instead (in a later version), since its a lot of data. The example that I linked to is a reduced geometry.

Regards,

Tommy

Hey-

things like this can happen when the renderer (VML in your case) runs
out of coordinate space. If you can serve your vector data through
something that supports a BBOX filter (i.e. e.g. a WFS or FeatureServer,
but not a static file), you can use a BBOX strategy on your vector layer
to avoid the issue.

Regards,
Andreas.
