I am trying to export styled points from QGIS to KML/KMZ format. The points are styled according to an attribute value ("Subsidence"). I want to export the KML/KMZ with the symbology, but when I open the result in Google Earth, it isn't preserved. Can someone help me understand why and if there is a way to accomplish this?
QGIS styling is not directly exported in KML. You can, however, construct a style string in a special attribute called OGR_STYLE for each feature, and that will be interpreted if you export with the libkml driver. More details at Styling KML through LIBKML layer creation options
Styling is QGIS-specific and thus you can't just export it and see it in the same shape, color, size etc. in any other application (or only if it has a rendering that matches the one that is implemented in QGIS). Style is not standardized, but program-specific. The yellow markers of Goolge Earth will not be shown the same way in QGIS either (if you do the export the other way round).
I managed to solve this by splitting the vector layer into multiple vector layers based on the value I used to style the points. Then, I gave each file a single point style based on the value. After doing this I ended up with many vector files (one for each value) which I then merged in Google Earth Pro.
