Abstract

Using Mosaic Dataset to Manage the National Elevation Dataset
Track: National Mapping
Authors: Dr. Sam Arundel

The US Geological Survey (USGS) is investigating ESRI's Mosaic Dataset functionality for improving the data management and conversion processes required to maintain and update the National Elevation Dataset (NED). The NED update process integrates raster elevation terrain models from a variety of sources, including USGS contours, IFSAR, and LiDAR, into the 1/9-, 1/3-, and 1-arc second resolution NED data layers. The USGS assessment of Mosaic Dataset functionality to organize, manage, and ensure seamlessness of terabytes of data comprising the national elevation layers is described in this paper.
