TAGGED VECTOR CONTOURS (TVC) |
|
Source: Nebraska Department of Natural Resources Processed by: Data Bank (KM,GF) Tagged Vector Contour (TVC) A by-product of the DEM/DOQ development process is a set of files (one for each quad) that has the contour lines tagged with the elevation it represents. These are vector files. This set of coverages have some edge-matching completed and additional error detection and corrections have been applied. The contour intervals are the same as the 7½-quads they are derived from. Those are usually in feet and vary from 5-foot (generally along the Platte or other river valleys) to 20-foot (generally in the Sandhills) intervals with 10-foot contours being the most common throughout the State. There are a few quads in the northwest part of Nebraska that are mapped in meters and those have a contour interval of 5 meters. Following options are available to retrieve TVCs:
