We find locally free resolutions of length 1 for all Gieseker semi-stable sheaves on the complex projective plane having Hilbert polynomial P(m)=rm+c, where r=4, 5, 6. The corresponding moduli spaces are thus naturally stratified according to the type of resolution. The strata are quotients modulo certain algebraic groups and have concrete geometric descriptions.
