COVERAGE HA24_HUM - 1:24,000-scale Hydrographic Areas for Humboldt River Basin, Nevada

Listed in NASA Earthdata CMR

This data set was created to display the topographic and administrative hydrographic area boundaries for the Humboldt River Basin at 1:24,000-scale.

Description

This data set contains the topographic and administrative hydrographic area boundaries for the Humboldt River Basin at 1:24,000-scale. Introduction The hydrographic area (HA) boundaries for the State of Nevada were delineated on 1:250,000-scale maps, in cooperation with the U.S. Geological Survey (USGS), and then redrawn and published at 1:500,000-scale (Cardinalli and others, 1968).

This 1:500,000-scale map is the current reference for HAs in Nevada and is used as a guide in delineating the HAs at 1:24,000-scale. This data set contains the topographic and administrative HA boundaries for the Humboldt River Basin. The Humboldt River Basin HAs were delineated and digitized from 1993 to 1998 using 1:24,000-scale USGS topographic maps.

Reviews The digital data in this data base has gone through a rigorous, multi-level, quality-control process that ensures the data set is a fair representation of the source map. If errors are encountered in this data set, it will be appreciated if the user would pass this information to the Metadata_Contact. Two reviews were done.

The reviewers were asked to check metadata and other documentation files for completeness and accuracy. Reviewers were asked to check the topological consistency, tolerances, projections, and geographic extent.

Notes

It should be noted that, although the boundary lines between hydrographic areas generally coincide with true topographic basin divides, some of the lines are arbitrary divisions that have no basis in topography, but are administrative and specified by Nevada Division of Water Resources. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in non-proprietary form, as well as in ARC/INFO format, this metadata file may include some ARC/INFO-specific terminology.
