We present three dimensional ( 3D ) dust mapping of 12 supernova remnants ( SNRs ) in the Galactic anti-center ( Galactic longitude l between 150 \degr and 210 \degr ) based on a recent 3D interstellar extinction map .
The dust distribution of the regions which cover the full extents in the radio continuum for the individual SNRs are discussed .
Four SNRs show significant spatial coincidences between molecular clouds ( MCs ) revealed from the 3D extinction mapping and the corresponding radio features .
The results confirm the interactions between these SNRs and their surrounding MCs .
Based on these correlations , we provide new distance estimates of the four SNRs , G189.1+3.0 ( IC443 , d = 1729 ^ { +116 } _ { -94 } pc ) , G190.9-2.2 ( d = 1036 ^ { +17 } _ { -81 } pc ) , G205.5+0.5 ( d = 941 ^ { +96 } _ { -94 } or 1257 ^ { +92 } _ { -101 } pc ) and G213.0-0.6 ( d = 1146 ^ { +79 } _ { -80 } pc ) .
In addition , we find indirect evidences of potential interactions between SNRs and MCs for three other SNRs .
New distance constraints are also given for these three SNRs .
