Elevation-derived hydrography acquisition specifications
Hydrographic features derived from U.S. Geological Survey (USGS) 3D Elevation Program data, and collected for use by the USGS, must meet the specifications described in this document. The specifications described herein pertain to the final product delivered to the USGS, not to methods used to derive the hydrographic features. The specifications describe the collection area, spatial reference systAuthorsSilvia Terziotti, Christy-Ann ArchuletaElevation-derived hydrography—Representation, extraction, attribution, and delineation rules
With the increasing availability of 3D Elevation Program (3DEP) quality high resolution elevation data across the United States and the pressing need for better integrated elevation and hydrography data, the U.S. Geological Survey is developing guidance to improve the horizontal and vertical alignment of these datasets. The U.S. Geological Survey is providing the Elevation-Derived Hydrography—AcquAuthorsChristy-Ann Archuleta, Silvia TerziottiThe National Map seamless digital elevation model specifications
This specification documents the requirements and standards used to produce the seamless elevation layers for The National Map of the United States. Seamless elevation data are available for the conterminous United States, Hawaii, Alaska, and the U.S. territories, in three different resolutions—1/3-arc-second, 1-arc-second, and 2-arc-second. These specifications include requirements and standardsAuthorsChristy-Ann M. Archuleta, Eric W. Constance, Samantha T. Arundel, Amanda J. Lowe, Kimberly S. Mantey, Lori A. Phillips1-Meter Digital Elevation Model specification
In January 2015, the U.S. Geological Survey National Geospatial Technical Operations Center began producing the 1-Meter Digital Elevation Model data product. This new product was developed to provide high resolution bare-earth digital elevation models from light detection and ranging (lidar) elevation data and other elevation data collected over the conterminous United States (lower 48 States), HaAuthorsSamantha T. Arundel, Christy-Ann M. Archuleta, Lori A. Phillips, Brittany L. Roche, Eric W. ConstanceAutomated delineation and characterization of watersheds for more than 3,000 surface-water-quality monitoring stations active in 2010 in Texas
The U.S. Geological Survey (USGS), in cooperation with the Texas Commission on Environmental Quality, developed computer scripts and applications to automate the delineation of watershed boundaries and compute watershed characteristics for more than 3,000 surface-water-quality monitoring stations in Texas that were active during 2010.
