[Talk-us-massachusetts] New Mass GIS Newletter link

[Alan Bragg]

I'd like to know where boundaries in osm are not near property edges in the

Maybe someone could figure out how to compare the new lidar with the edges
of lakes and rivers.
I imagine will find enough to keep us busy by comparing the new master
address file with our data.
