Hi, I don't know what is GWC. This mailing list is about PostGIS.
This looks like the overlay does not do proper reprojection and instead just takes proportion of latitude and longitude. You need to reproject all the coordinates into underlay's projection before working with linear proportions. сб, 13 окт. 2018 г. в 2:07, Aaron Edwards <[email protected]>: > We are showing US States using GWC. > > > > When the user selects a state, we show a “selected polygon” layer on top > of it: > > > > https://b3insight.com/Content/Images/US.png > > > > As you can see from the image, the yellow Highlighted WMS layer is > incorrectly rendering on top of the red GWC layer of states. > > > > Both are the same layer in Geoserver.
