- Abstract:
-
This data set contains points representing NHD hydrographic landmark features. The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The data was originally published by the USGS then it is modified by the NHD data steward for Florida (FDEP). When received from FDEP, this data was originally in geodatabase format. When in shapefile format the data loses the network functionality of the geodatabase. Please contact the FDEP if you need the original geodatabase.
- Purpose:
-
The NHD is a national framework for assigning reach addresses to water-related
entities, such as industrial discharges, drinking water supplies, fish habitat areas,
wild and scenic rivers. Reach addresses establish the locations of these entities
relative to one another within the NHD surface water drainage network, much like
addresses on streets. Once linked to the NHD by their reach addresses, the
upstream/downstream relationships of these water-related entities--and any
associated information about them--can be analyzed using software tools ranging
from spreadsheets to geographic information systems (GIS). GIS can also be used
to combine NHD-based network analysis with other data layers, such as soils, land
use and population, to help understand and display their respective effects upon
one another. Furthermore, because the NHD provides a nationally consistent
framework for addressing and analysis, water-related information linked to reach
addresses by one organization (national, state, local) can be shared with other
organizations and easily integrated into many different types of applications to the
benefit of all.

In May, 2011, the existing Florida NHD100K, NHD 24K as downloaded May 2,
2011 from the USGS NHD, Hydrologic Units, GNIS alternate names and
relationships were combined into one file geodatabase for public distribution and
use. Notable changes to the database since the previous download in December
2010 are as follows: Full photo revision to Lower Suwannee (03110205) and
Apalachee Bay-St. Marks (03120001) sub basins; Partial photo revision to
Withlacoochee (03100208) and Lower Suwannee (03110205) sub basins; Removal
of duplicate features within Myakka (03100102) sub basin; Database maintenance
was performed on Oklawaha (03080102), Choctawhatchee Bay (03140102), Cape
Canaveral (03080202), Lower Choctawhatchee (03140203), Pea (03140202),

- Data_Quality_Information:
-
- Attribute_Accuracy:
-
- Attribute_Accuracy_Report:
-
GeoPlan relied on the integrity of the attribute information within
the original data.
- Logical_Consistency_Report:
-
Points, nodes, lines, and areas conform to topological rules. Lines intersect only at
nodes, and all nodes anchor the ends of lines. Lines do not overshoot or
undershoot other lines where they are supposed to meet. There are no duplicate
lines. Lines bound areas and lines identify the areas to the left and right of the lines.
Gaps and overlaps among areas do not exist. All areas close.
- Completeness_Report:
-
The completeness of the data reflects the content of the sources, which most often
are the published USGS topographic quadrangle and/or the USDA Forest Service
Primary Base Series (PBS) map. The USGS topographic quadrangle is usually
supplemented by Digital Orthophoto Quadrangles (DOQs). Features found on the
ground may have been eliminated or generalized on the source map because of
scale and legibility constraints. In general, streams longer than one mile
(approximately 1.6 kilometers) were collected. Most streams that flow from a lake
were collected regardless of their length. Only definite channels were collected so
not all swamp/marsh features have stream/rivers delineated through them.
Lake/ponds having an area greater than 6 acres were collected. Note, however,
that these general rules were applied unevenly among maps during compilation.
Reaches codes are defined on all features of type stream/river, canal/ditch,
artificial path, coastline, and connector. Waterbody reach codes are defined on all
lake/pond and most reservoir features. Names were applied from the GNIS
database. Detailed capture conditions are provided for every feature type in the
Standards for National Hydrography Dataset available online through
<http://mapping.usgs.gov/standards/>.
This statement is generally true for the most common sources of NHD data. Other
sources and methods may have been used to create or update NHD data. In some
cases, additional information may be found in the NHDMetadata table.
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
Statements of horizontal positional accuracy are based on accuracy statements
made for U.S. Geological Survey topographic quadrangle maps. These maps were
compiled to meet National Map Accuracy Standards. For horizontal accuracy, this
standard is met if at least 90 percent of points tested are within 0.02 inch (at map
scale) of the true position. Additional offsets to positions may have been introduced
where feature density is high to improve the legibility of map symbols. In addition,
the digitizing of maps is estimated to contain a horizontal positional error of less than
or equal to 0.003 inch standard error (at map scale) in the two component directions
relative to the source maps. Visual comparison between the map graphic (including
digital scans of the graphic) and plots or digital displays of points, lines, and areas, is
used as control to assess the positional accuracy of digital data. Digital map
elements along the adjoining edges of data sets are aligned if they are within a 0.02
inch tolerance (at map scale). Features with like dimensionality (for example,
features that all are delineated with lines), with or without like characteristics, that
are within the tolerance are aligned by moving the features equally to a common
point. Features outside the tolerance are not moved; instead, a feature of type
connector is added to join the features.
This statement is generally true for the most common sources of NHD data. Other
sources and methods may have been used to create or update NHD data. In some
cases, additional information may be found in the NHDMetadata table.
- Vertical_Positional_Accuracy:
-
- Vertical_Positional_Accuracy_Report:
-
Statements of vertical positional accuracy for elevation of water surfaces are based
on accuracy statements made for U.S. Geological Survey topographic quadrangle
maps. These maps were compiled to meet National Map Accuracy Standards. For
vertical accuracy, this standard is met if at least 90 percent of well-defined points
tested are within one-half contour interval of the correct value. Elevations of water
surface printed on the published map meet this standard; the contour intervals of
the maps vary. These elevations were transcribed into the digital data; the
accuracy of this transcription was checked by visual comparison between the data
and the map.
This statement is generally true for the most common sources of NHD data. Other
sources and methods may have been used to create or update NHD data. In some
cases, additional information may be found in the NHDMetadata table.

-
The processes used to create and maintain high-resolution NHD data can be found
in the table called "NHDMetadata". Because NHD data can be downloaded using
several user-defined areas, the process descriptions can vary for each download.
The NHDMetadata table contains a list of all the process descriptions that apply to
a particular download. These process descriptions are linked using the DuuID to
the NHDFeatureToMetadata table which contains the com_ids of all the features
within the download. In addition, another table, the NHDSourceCitation, can also
be linked through the DuuID to determine the sources used to create or update
NHD data.

- Process_Description:
-
GeoPlan Center downloaded the NHD GeoDatabase from the Florida Department
of Environmental Protection in November 2011. The data was exported to shapefile
and defined with the FGDL Albers projection file.
This data was originally produced by U.S. Geological Survey in cooperation with
U.S. Environmental Protection Agency, USDA Forest Service, and other Federal,
State and local partners. The Florida Data Stewards (FDEP) then update the data.
The original metadata from USGS is used with the original publication date,
however, the time period of content has been changed to the last update made by
FDEP.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.
Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,
modifying, contributing or distributing the materials.
A note about data scale:
Scale is an important factor in data usage. Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.
Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:
