Let Fq(n)be the n-dimensional vector space over a finite field Fq, and let Gnbe the symplectic group Spn(Fq) where n=2ν; or the unitary group Un(Fq) where q=q02. For any two orbits M1and M2of subspaces under Gn, let L1(resp. L2) be the set of all subspaces which are sums (resp. intersections) of subspaces in M1(resp. M2) such that M2⊆L1(resp. M1⊆L2). Suppose L is the intersection of L1and L2containing {0} and Fq(n). By ordering L by ordinary or reverse inclusion, two families of atomic lattices are obtained. This article characterizes the subspaces in these lattices and classifies their geometricity.
