Abstract
Indicator sets arising from symplectic line-spreads of a 3-dimensional projective space are characterized. Moreover, locally Hermitian ovoids of a Hermitian surface 
(3, q2) are studied in terms of “non-equivalent” associated indicator sets. Translation locally Hermitian ovoids of (3, q2) arising from regular spreads of PG(3, q), Kantor semifield spreads of PG(3, q) and semifield spreads of PG(3, q) with center 
are also investigated.
