Given electric field, find surface or charge density

[fishingspree2]

We know that ∇.D = ρ_V

My question is, if D is due to a linear or a surface charge distribution, can we apply this equation and get a surface or linear charge density?

Thank you very much

Yes, but I think, you have to sort of integrate within the boundary conditions. There is lot of information regarding this on google, if you do a search.
