Description:
|
At this moment there is a drawing optimization that happens only for shapefiles that avoids painting superimposed points.
We have a use case when we want to render superimposed points with different azimuths. Because of optimization geoserver will render only the first feature resulting a feature showing only one azimuth instead of rendering a “flower”.
