The National Spatial Data Infrastructure (NSDI)
Framework is a collaborative initiative to
develop geographic datasets that are compatible
based upon spatial location and content. The
Framework approach allows data collected for
variety of reasons and agencies to work together
seamlessly which can ultimately reduce project
costs and increase interagency cooperation. The
Framework Data Content Base Standards Suite
dictates the requirements for Framework
data. This course covers the fundamentals of the
Framework Data Theme Hydrography as developed by
the Framework Data Content Standard. It is
designed for users who are both interested in an
overview of the Framework Data Content Standard
Hydrography theme as well as designers and
developers implementing Framework data, and
associated tools.

What is HydroGraphy
Related scientific field
Hydrology The scientific study of the waters of
the earth, especially with relation to the
effects of precipitation and evaporation upon the
occurrence and character of water in streams,
lakes, and on or below the land surface. In terms
of the hydrologic cycle, the scope of hydrology
may be defined as that portion of the cycle from
precipitation to re-evaporation or return to the
water of the seas. Applied hydrology utilizes
scientific findings to predict rates and amounts
of runoff (river-forecasting), estimate required
spillway and reservoir capacities, study
soil-water-plant relationships in agriculture,
estimate available water supply, and for other
applications necessary to the management of water
resources.
The study of waters (including oceans, lakes, and
rivers) embracing either (a) their physical
characteristics, from the standpoint of the
oceanographer or limnologist or (b) the elements
affecting safe navigation, from the point of view
of the mariner. Hydrographic data is a comprised
of data that contains information about surface
water features such as lakes, ponds, streams,
rivers, springs and wells. This data is often
collected in various forms, including remote
sensing, field work, and interpolation. This
data, can be developed or converted to digital
spatial datasets which can be used with
Geographic Information Systems (GIS) for a
variety of purposes. The National Hydrography
Dataset (NHD) is one such dataset examples from
the NHD will be used throughout this course to
help illustrate Hydrography and the Hydrography
Framework Standard.

Types of Hydrography
What is the NHD?
The National Hydrography Dataset (NHD) is a
comprehensive set of digital spatial data that
encodes information about naturally occurring and
constructed bodies of water, paths through which
water flows, and related entities.
In general terms hydrography is defined as the
study of water thus it stands to reason that
hydrography data is usually a water source.
Clearly rivers and lakes fall within this
category but so do pipelines, canals, swamps,
and reservoirs. In fact there are 53 different
types of hydrographic data referenced by the NHD.
Thus it is key to express hydrographic data in
various formats points, lines, and polygon
vector data. Additionally the data needs to
include the appropriate attribute information to
give a user a true indication of what is data is
being represented.
Are the NHD and Framework the Same?
Although this question seems simple enough, the
answer is somewhat more difficult to answer. In
reality the NHD is a nationwide dataset that
represents hydrographic data based on a specific
set of rules or data model. However this data
model is not the same data model that is outlined
in the Framework hydrology standard. Thus tools
and crosswalks will need to be developed to
convert data between the two different models.

What is the Hydrography standard

• The Hydrography Framework Data Content Standard
• One of the seven themes defined as Framework
  data
• Establishes a baseline for hydrographic data
  collection and creation
• Builds on the Framework Data Content Base
  Standard.
• Only when a dataset meets both the requirements
  set forth in a thematic standard part(s) and
  the Framework Base Standard can it be considered
  Framework data.

12
Purpose for the Standard
Quick Facts
Each standard part was developed and edited by
thematic experts Certain themes have additional
pieces to address sub components. For example
Transportation has separate parts to address
different elements (i.e. roads, airports, etc.)
However the Hydrography standard incorporates all
hydrographic features within one standard.
The purpose of Geographic Information Framework
Data Content Standard, Part 6 Hydrography is to
establish the content requirements for the
collection and interchange of hydrography
features and to facilitate the maintenance and
use of that information by all users of
geographic information. The Hydrography part
identifies and defines terminology, encoding
schema, and the data components required for
describing hydrographic features, along with the
metadata needed for the hydrography data
exchange. This part specifies the content and its
organization necessary for the successful
interchange of hydrography data. The scope of the
Hydrography part is limited to the information
regarding surface water features and hydrographic
networks for the purpose of cartography and
network analysis and is intended to be applicable
at a variety of scales.
13
Goals for the Hydrography Standard

• The goal of the Hydrography part of the
  Framework Data Content Standard is to provide
  common definitions and syntax to enable
  collaborative development, use, and exchange of
  hydrography data.
• It is the intent of the part to set a common
  baseline of information content for exchange
  within the hydrographic community that will
  enhance data sharing and applications
  development when used with standards-based Web
  services or file transfer.
• It is anticipated that multiple representations
  of hydrographic features will exist within the
  broader community. Policies have been or will be
  established for describing, maintaining, and
  exchanging the various representations of
  features within specific application
  communities, such as the NHD. This part will
  accommodate the exchange of these multiple
  representations.
• This part supports the mapping and conversion of
  native data in any format into a common
  representation for exchange over the Web or as
  files. Encoding of hydrography data for
  transfer, based on the models in this part, is
  described in the Framework Data Content Base
  Standard.
• The audience of this part of the standard
  includes hydrography data users, maintainers,
  and distributors. Specific guidance on the
  implementation of this part for specific user
  communities will be made through external
  guidance or policy documents.

14
Capacities for the Hydrography Standard
More Information
The goals, tasks, and accomplishments of this
standard were determined by the Hydrography
Modeling Advisory Team (MAT) a group of domain
experts convened to define a common set of
hydrography information content.

• The development of this part of the Framework
  Data Content Standard will greatly assist in
  mitigating the following issues
• Duplication of data and application development
• Complications exchanging hydrography data and
  information
• Difficulties integrating data
• Poor framework/support for analytic activities
• Difficulties managing multiple representations
  of features

In this module you will learn about the three
different requirements for Framework Hydrography
data, as specified in the standard. Each
requirement is addressed as a separate topic,
however more attention may be given to certain
requirements as they are the most crucial
requirements for creating Framework quality
hydrography data. Many of the requirements are
specific UML features. For these requirements
the a brief description of the component will be
included. Please see the UML chart and
associated tables, included as an appendix for
more specifics. Additionally encoding and

for the Framework Hydrography Standard. This
diagram shows the components and relationships
that comprise the Framework Hydrography Standard.

• The following list is a comprehensive list of
  each UML object specified in the hydrography
  standard. Each one coresponds to a box on the
  UML diagram on the previous slide. For more
  detailed information please see the Appendices
  which have a copy of the compete standard
  including tables outlining the specifics of each
  UML object.
• HydroCollection is the container for the
  features packaged in an exchange of hydrographic
  information.
• HydroFeature is an abstract class that captures
  the characteristics of the hydrographic feature.
  As the core component of the model, HydroFeature
  has several significant associations to other
  classes. HydroFeature has HydroElement and
  HydroComplex subclasses.
• HydroElement Basic hydrographic features with
  explicit geometry. HydroElement inherits all
  properties (generalizes) from the abstract parent
  class, HydroFeature.

next Topic
Hydrography Requirements Continued
26
Framework Data Standard Hydrography Requirements

• HydroComplex is an aggregate of HydroElement.
  The HydroComplex may impose property requirements
  onto the associated HydroElements. For example, a
  HydroComplex of Reach requires measure values
  based on the extent of the Reach, not of the
  HydroElements that make up the Reach. As an
  aggregate representation, a HydroComplex is
  retired if the HydroElements that make up the
  HydroComplex are retired. The reverse situation
  does not apply. HydroComplex inherits all
  properties from the parent abstract class,
  HydroFeature. These properties are not shown in
  the table below.
• FeatureRelationship describes binary
  relationships between feature instances. The
  order of the elements in the relationship is
  explicit and is represented using a
  self-association in the UML model. The
  RelationshipAttribute qualifier will have
  relevance to a specific RelationshipType.
• Event is an object supports the linking of
  external attribute information to a portion of a
  HydroFeature, either HydroElement or
  HydroComplex. Events can be of two types
  MeasuredEvent or UnmeasuredEvent. MeasuredEvents
  are those that reference portions of features
  that participate in the linear reference model.
  UnmeasuredEvents are those that reference
  portions of features that do not participate in
  the linear reference model.

next Topic
Hydrography Requirements Continued
27
Framework Data Standard Hydrography Requirements

• MeasuredEvent represents a point or span along a
  linear feature. In order to have MeasuredEvents,
  a linear feature must participate in the linear
  reference model. A MeasuredEvent always has a
  StartMeasure and, if it represents a span along a
  feature, it also has an EndMeasure. The measures
  specifies the exact location of the event
  relative to the addresses/measures along the
  referenced feature. A MeasuredEvent may also have
  a geometric representation (inherits location)
  which provides an independent location for the
  event. MeasureEvent inherits all properties from
  the parent class, Event.
• UnmeasuredEvent may be linked to any feature
  that does not participate in the linear reference
  model. The referenced feature may be a
  zero-dimensional, one-dimensional, or
  two-dimensional feature and may be either an
  HydroElement or HydroComplex feature.
  UnmeasuredEvents must have a location (geometry)
  that specifies the location of the event
  independent of the geometry of the referenced
  feature. The geometry may be of point, line, or
  polygon as declared in the ElementGeometry Union
  class. UnmeasuredEvent inherits all properties
  from the parent class, Event. These properties
  are not shown in the table below.

1. Nameobject holds feature names that are managed
   by a naming authority. The authority may be a
   recognized authority such as the Board of
   Geographic Names or an un-recognized authority
   such as a local hydrography maintainer. An
   ExchangeCollection may contain names from
   different authorities. Feature names are linked
   to HydroFeatures, both HydroElement and
   HydroComplex, in a many-to-many relationship.
   This permits a given feature to have names from
   different authorities. It also permits a single
   name to be linked to HydroFeature instances that
   represent parts of a named feature.
2. HydroFeatures, both HydroElement and
   HydroComplex, will have more than one
   representation in the hydrography community. A
   representation is one instance combination of
   feature attributes and geometry variation in
   one characteristic constitutes a new
   representation. Each HydroFeature instance within
   a given ExchangeCollection will have a single
   representation and the Representation object
   describes which representation is being
   exchanged. If the ExchangeCollection contains
   more than one representation for a given
   HydroFeature, there will be a feature instance
   (with unique identifier) for each representation
   in the ExchangeCollection.

11) Measurement is used to store empirical
measurements of features such as real- world
reported elevation, length, area, and depth
typically of values portrayed on topographical
maps. HydroElement, HydroComplex, and Event
features may have one or more ReportedMeasurements
. 12) ComputedNetworkValues The National Hydro
Dataset (NHD) includes a number of computed
values for hydrographic features (HydroElements)
with basic geometries. These properties are only

13) Common framework classes Three classes are
shown in Figure 1 that are included from the Base
Document (Part 0) for completeness. These classes
are ExtendedAttribute, Identifier, and
ExternalResource. The ExtendedAttribute object,
described in Part 0, provides the ability to link
additional attributes to HydroFeature instances,
both HydroElement and HydroComplex. The
ExtendedAttribute must have an authority which is
documented with an authority (ISO19115Responsibl
eParty). The ExtendedAttribute may be documented
through a URL to an ExternalResource object
instance. The fuller description of this behavior
is provided in the Part 0 but the classes are
only shown here for convenience. The
ExternalResource object provides the ability to
link Internet URLs to HydroFeatures, both
HydroElement and HydroComplex, to Events, to
ISO19115ResponsibleParty, and to
ExtendedAttributes. There are a number of
different types of ExternalResources as
enumerated in the ResourceType code list.
Identifier stores a set of related properties
required for the management of information within
a namespace. The identifier, a description, and a
reference to an assigning authority are provided.
The ResponsibleParty class comes from the ISO
19115 metadata concept of the same name but is
implemented here to simplify the possible
associations and recursion in the data model.
ISO19115ResponsibleParty provides descriptive
details of an organization to which one can go
and get additional contextual information.

14) External packages several UML packages of
structured information are used or referenced
from ISO sources in this part of the standard.
These include geometry and linear referencing
constructs from other ISO standards (GM_Object
from ISO19107, CharacterString and Date from
ISO/TS 19103). The inclusion of these packages of
information complements the model. 15) Code
lists and enumerations the code lists presented
in Figure 2 represent known values that are
encouraged to promote interoperability. Code
lists, by their nature are not closed
enumerations and are not intended to be
exhaustive. In fact, they might be placed online
and would support controlled update by the
community. In implementation, strict validation
may include tests for the presence of these
codes, whereas lax validation may permit these
and additional code values.
next Topic
Encoding and Implementation
32
Encoding and implementation
The Bigger Picture
The Framework Standards do not have a specific
application schema that can be implemented.
Implementation of the Framework Standards in
relation to data and tool creation occurs at the
thematic level. Each thematic part complies with
the Framework Base Standard. As such a road
layer (for example) created in accordance with
the Framework Transportation Roads part meets all
Framework requirements.

• The process of encoding is simply formatting or
  structuring data in a regulated manner. The
  Framework standards are encoded by applying the
  application schemas through the use of several
  different modeling and markup languages
• Unified Modeling Language (UML)
• Extensible Markup Language (XML)
• Geographic Markup Language (GML)
• Specific knowledge of each language is important
  for data and tool designers for more information
  see the Framework Base Standard Training
  Materials.

Hydrographic Applications
It is important to remember that different
hydrographic based applications have specific
data and information requirements. Thus the
Hydrography Framework part needs a complex data
model to support these needs.

• Design Concepts
• The Hydrography Component has 8 key design
  concepts defined by the standard
• Core component of the standard and model are the
  hydrologic features
• All features have geometry
• Features are classified by type, and qualified by
  attributes
• Features may have relationships with other
  features
• Common definition of features is needed for
  data sharing
• Permanent identifiers for features are managed by
  an authority
• Linear referencing is supported through permanent
  features, identifiers, and measurement references
• Multiple representations of a feature can exist
  and are managed in a community

Hydrography Code lists
A code list is designed to limit the available
choices of values that a feature can have.
Although code lists are not necessarily
comprehensive indices, they are designed to
define the most commonly used values in a
standardized format which promotes data
interoperability. In fact often strict
implementation rules and validation assessments
will test for the presence of a code list value,
while more lax rules will allow for the presence
of additional code values. The diagram to the

interoperability of hydrographic data.
