“A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y). Digital Elevation Models are a “bare earth” representation because they only contain information about the elevation of geological (ground) features, such as valleys, mountains, and landslides, to name a few. They do not include any elevation data concerning non-ground features, such as vegetation or buildings...”

Does anyone know of any concrete ways the old USGS scribed map products or their derivatives are used today?
For a while, the line work was turned into raster products, I believe, and then into digital elevation models?
Do any part of of the old topo map products still have use or relevance, or have they seen their last hurrahs?
