What sources of elevation data were used to create contours?

The 100-foot contours were derived from 3DEP (formerly National Elevation Dataset) one arc-second resolution data, which was sub-sampled to a cell size of three arc-second. The 50-foot contours were also derived from one arc-second data. Large scale contours were derived from 1/3 arc-second resolution data for US Topo products.
