We describe the spaces of the positive and tropical points of the moduli space $\mathcal{ P}_{ PGL_2,\Sigma}$ introduced by Goncharov--Shen [GS19] as certain Teichm\"uller and lamination spaces, respectively, with additional data of pinnings. In the case where the surface $\Sigma$ has no punctures, we obtain the formulae relating various functions on the Teichm\"uller space with pinnings: $\lambda$-lengths, cross ratio coordinates, and Wilson lines. A topological description of the tropicalized amalgamation map is given in terms of $\mathcal{ P}$-laminations. Based on our topological study of these "$\mathcal{ P}$-type" spaces, we investigate the compatibility of the Fock--Goncharov duality maps $\mathbb{ I}_\mathcal{ A}$, $\mathbb{ I}_\mathcal{ X}$ constructed by [FG06,FG07,MSW13,GS15] under the extended ensemble map. We also discuss the amalgamation of bracelet bases.
