We have had good results of printing from the DLGs, but even that requires significant work placing names and labeling contours. NY and NJ are not high on their list. Much of the commercially available data has copyright restrictions which make it unusable for anything other than private viewing. It typically is also at too low resolution. Otherwise, roads, streams and other objects are moved within that 40 foot range to make a more visually pleasing product.
Benchmarks are points of known elevation.
The horizontal positions of benchmarks in the National Geodetic Data Base are known to within 6 arc seconds in Latitude and Longitude. That's going to be plotted to an accuracy of 0.01 inches on the paper map. Benchmarks ain't Triangulation Stations, and vice-versa. Presented to TC Board for approval to go ahead with grant process.
