I am trying to display a GeoPackage of points with OpenLayers from GeoServer; however when I try and render the map the points appear to be duplicated.

When I generate a CSV with Layer Preview in GeoServer, the points appear to be correct, but when I view the PNG or OpenLayers they appear to be duplicated in a repeating pattern, as shown in this image:

Duplicated points

Why may this be the case? I have tried everything from disabling tile caching to changing the projection (I'm using ESPG:4326) but nothing seems to work.

EDIT:

Below is a sample of the CSV file exported from Layer Preview in GeoServer.

  • If you zoom in do the repeated ones disappear?

  • The image provided is just the static PNG image from Geoserver, but in the OpenLayers view they do disappear as I zoom in.

  • I'd put a base map behind the points, but it looks like you are looking at number of world's at that zoom level

  • That's what I tried with the OpenLayers preview; a base map behind. The base map works fine when you zoom out then the points appear to duplicate to other locations on the map.

The coordinates are clearly not in EPSG:4326, map wrapping is likely porting over the points that are beyond -180°/180° into the sane range. I see two options:

  • Give them a true projected CRS, e.g., EPSG:32632, and reconfigure the layer from scratch
  • Disable map wrapping in the WMS settings

  • Thank you, disabling map wrapping fixed it. I wasn't sure what CRS to use since it was a fictional map, but I may consider choosing a projected CRS.
