"DecoTurf" is not a common name, but a brand name. It  is also not a genericized trademark. We may need a broader term to classify surfaces. "Hardcourt" seems to be used exclusively for tennis courts, literally does not refer to a certain material. However, most of hardcourt surface are acrylic based, which is one of the ITF's classification of tennis court surface types. So I think "acrylic"  is a suitable value to classify the surface of the courts.


Acrylic I tend to associate with paint and plastics.


From satellite imagery I simply used 'paved' where I can determine it is not a 'natural' surface.


Only some ~600 uses of DecoTurf.

Only some ~20 uses of Hardcourt.

Surface is used some 31,000,000 times so the above 2 may not be rendered anyway being such a small proportion.. possibly lumped into 'paved' if anyone bothers.
