I have a layer of Points with some attributes in GeoServer. Is it possible to create a style that would combine all the points in this layer in a line according to "date" attribute order? I want to receive a list of points through WFS service and single line through WMS service from the same layer.

EDIT: I use PostgreSQL with PostGIS.

No. SLD cannot do this.

But you can create SQL Views from GeoServer:

Go to Layer -> New Layer -> Choose your PostGIS Store from the Dropdown -> Configure new SQL view ...

Then you can write something like this using ST_MakeLine as SQL statement:

SELECT ST_MakeLine(the_geom ORDER BY date) as line FROM your_points_table;

For the WFS Service you will receive the same line of course. But you could split the line to points from the WFS in your client afterwards.

  • Idea should work but that SQL for sure not. See better examples in postgis.net/docs/ST_MakeLine.html.
