资源简介:
This dataset was created as a layer of a geographic information system (GIS)
to calculate river miles on the Humboldt River. The currentness and accuracy of
the digital orthophoto quadrangle (DOQ) source exceeded that of other available
data.
This data set contains the main stem of the Humboldt River as defined by
Humboldt Project personnel of the U.S. Geological Survey Nevada District, 2001.
The data set was digitized on screen using digital orthophoto quadrangles from
1994.
Reviews
The digital data in this data set 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 found in this data set, it will be appreciated if
the user would pass this information to the Metadata_Contact.
Two formal 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.

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 nonproprietary form, as well as in ArcInfo
format, this metadata file may include some ArcInfo-specific terminology.
