SLD GeoServer COPY of styled labels from QGIS -with a created centroid - every label moved manually with X and Y on different places
Geographic Information Systems Asked by Viktor on January 29, 2021
In QGIS both in line, point and polygon type layers (for rivers, settlements, lakes..) I created labels for the objects – I created a field X and Y (Decimal Number), so that I define their location (look at picture) – manually. Basically I move every label separately from one another, and that label has it’s specific coordinates. This is 2 years work now, so the new QGIS easy-fast option for manually moving labels was not yet created.
Now the question is this:
I invested a lot time now and I can not find a solution, inside or outside GeoServer documentation – I use SLD style export for all of the layers in GeoServer, that I have no problems styling. However, I can not find a way to style the labels as such different positions, that they are visualized for every specific location with X and Y in GeoServer. So I can not get the same result that I have in QGIS – in GeoServer.
I manage to use all of the other SLD styles – so that they are offset from the point in many different ways, but every single label is offest the same way as the others.
Here are 2 SLD examples for point type that is exported from QGIS where I use this manual placement of labels. .
1 Is the basic one, pure export from QGIS. But it won’t load, because of map units. So >>2>> fixed one>>
2 Is modiffied with a line or two,so that it works – because of map units and projection.
And in the end, I show you a picture: How all 3 labels in GeoServer are on the right.

I link a sample point lable file, styles and pictures.
[Sample point shapefile – styled. Same style is in SLD above](https://dox.abv.bg/download?id=35498f44f2# – Линк за сваляне)
One Answer
You need to construct the point you would like the label to appear from your X and Y columns and then tell the TextSymbolizer to use that geometry to place the label.
I would use something like:
<se:TextSymbolizer>
<se:Geometry>
<ogc:Function name="geomFromWKT">
<ogc:Function name="Concatenate">"Point(",ogc:PropertyName(X)," ", ogc:PropertyName(Y),")"</ogc:Function>
</ogc:Function>
</se:Geometry>
<se:Label>
<ogc:Function name="strToUpperCase">
<ogc:PropertyName>name_old</ogc:PropertyName>
</ogc:Function>
</se:Label>
A full list and description of the available functions is here.
