1 Introduction

This part of the standard responds to the need for common
definitions of spatial features in the process of data transfer.
The conceptual model and defined terms are the foundation for
exchanging data between existing digital cartographic systems and
may also be used as a viable approach to creating a new spatial
feature file.

Traditional map symbols and their digital code equivalents often
refer to real world features which have been defined only in the
mind of the cartographer responsible for compiling the data. Even
when agencies make an effort to define systematically the features
portrayed in their data bases, these definitions are likely to
vary from one organization to another. Thus, agreement on a
common format for data exchange is not sufficient to ensure that
the information provided by the supplier organization will be
meaningful or useful to the receiving organization.

In order to facilitate transfer of data that is meaningful both to
exporters and to importers, a common bridge of well understood
feature definitions is required. The feature and attribute lists
and definitions contained in the annexes to part 2 are a first
step in this direction. These lists and definitions are the
product of several years of effort during which approximately
2,600 definitions of geographic features were compared and
distilled into the initial list of 200 entity types. The
definitions of these entity types encompass the meanings found in
the definitions of over 1,200 alternative terms.

1.1 Purpose

The purpose of part 2 is to provide a common classification and
meaningful definitions for the spatial features identified in a
transfer.

1.2 Objectives

Based on the sources consulted at the time of the preparation of
this part of the standard, existing hydrographic and topographic
features could, with few exceptions, be encoded to one of the 200
defined standard entity types, thereby facilitating transfer
between organizations that might otherwise differ on the nuances
of their particular term for, or definition of, essentially the
same real-world phenomenon.

This list and these definitions are not presented as a definitive
product, but as a living compendium subject to future amendments
and extensions to meet the diverse needs of the spatial data
community.

The primary focus of this initial effort is on topographic and
hydrographic features, using sources available at the time of
preparation. Among the extensions anticipated are (a) updating to
accommodate new topographic and hydrographic products and (b)
addition of features from other disciplines concerned with the
exchange of spatially referenced geographic information.

Because all spatial data are likely to be exchanged in future,
organizations considering the development of new data bases may
use these standard categories as the basis for classifying
phenomena to be entered into such data bases.

2 Conceptual Model

2.1 Definitions

Spatial features are defined entity types and the representation
of instances of those types by spatial objects, as specified in
section 2 of part 1.

Spatial features shall be described by the concepts: Entity Type,
Entity Instance, Attribute, and Attribute Value; and by the terms
Standard and Included. These are defined as follows:

 Entity Type - the definition and description of a set into
 which similar entity instances are classified
 (e.g., bridge).

 Entity Instance - a spatial phenomenon of a defined type
 that is embedded in one or more phenomena of a
 different type, or that has at least one key
 attribute value different from the corresponding
 attribute values of the surrounding phenomena
 (e.g., the 10th Street Bridge).

 Attribute - a defined characteristic of an Entity Type
 (e.g., composition).

 Attribute Value - a specific quality or quantity assigned
 to an attribute (e.g., steel) for a specific
 Entity Instance.

 Standard Term - primary label of an Entity Type or
 Attribute (listed in annex A and B).

 Included Term - nonstandard label of an Entity Type or
 Attribute that is cross-referenced to a Standard
 Term of an Entity Type or Attribute. Included
 Terms used in more than one context may be cross-
 referenced to more than one Standard Term. (See
 annex C.)

2.2 Conceptual Approach

Many feature classification schemes are based on a hierarchical
system. This standard specifically avoids adopting any particular
hierarchy, in part because the higher level classifications differ
from one organization to another. Hierarchical classification, if
desired, may be constructed using standard attributes (such as
air/land/water, or manmade/natural) or through user-defined non-
standard attributes.

Network, relational, and object-oriented structures of feature
data may also be constructed from this non-hierarchized list of
standard features and attributes.

The features presented are defined independently of map or
geographic scale. Scale independence implies that no specific
spatial object (such as a point, line, or area representation) is
necessarily used to represent a given Entity Type. Further, the
list includes features defined at any level of geographic
interest, from mountain ranges and oceans to sidewalks and trees.

3 Scope and Field of Application

3.1 Scope

This part of the standard applies to the terms and definitions
used for Entity Types, Attributes, and Attribute Values in a
transfer. The terms may appear in the Data Dictionary/Definition,
Data Dictionary/Domain, Data Dictionary/Schema, Attribute Primary,
and Attribute Secondary module types as specified in part 1.
Definitions included in part 2 need not be repeated in a Data
Dictionary/Definition module in a given transfer, provided that
the Standard Term is used with its standard meaning.

The definitions of standard Entity Types are mutually exclusive,
but not exhaustive. Future extensions are anticipated.

3.2 Field of Application

There are two intended applications of this part of the standard
for systems employing spatial data in digital form: (a) new users
will have a model and the definitions needed for creating a
features set, and (b) transfer of the meaning of feature
information between existing systems will be facilitated.

4 Relationship to Other Standards

Federal Information Processing Standard codes exist for the
instances of certain Entity Types, for example states of the
United States (FIPSPUB 5-2). By implication, the Entity Type for
which these codes are provided (i.e., states and outlying areas of
the United States) has already been recognized as a standard
Entity Type.

Many federal agencies have agency standards for the classification
and definition of features within their particular realms of
responsibility. This standard is not intended to replace existing
agency standards, but to provide a basis whereby existing data can
be shared with other organizations that do not necessarily accept
the same terms and definitions for similar real-world phenomena.
Depending on the conformance level selected and the functional
requirements of a particular transfer, each agency may find it
useful to develop a cross-reference between its internal feature
and attribute classification system and the Standard Terms and
definitions in annexes A and B.

5 References

Selected references used in the preparation of part 2 of the
standard are included in annex F of part 1. The following is a
short list of the authors included in these references:

  Canadian Council on Surveying and Mapping
  Defense Intelligence Agency
  Defense Mapping Agency
  Monkhouse, F.J.
  Moore, W.G.
  Stamp, D.
  U.S. Geological Survey, Geographic Names Information
 System
  U.S. National Ocean Service

This list will be updated and expanded as additional feature lists
and definitions are submitted to the maintenance authority.

6 Conformance

All entity type, attribute, and attribute value terms and (or)
codes used in a transfer shall be defined. Non-standard Entity
Type and Attribute terms shall be specified through the use of the
Data Dictionary/Definition module. Attribute Value terms shall be
defined in the Data Dictionary/Domain module. See also part 1,
4.1.3.6 (Attributes).

The mandatory Features Level subfield of the Identification Module
specifies the conformance level of a transfer with respect to
feature definitions (see part 1, 5.2.1.2.3). Use of conformance
levels 2, 3, or 4 for features limits the scope of transfer and
are discouraged. Recurring needs to resort to non-standard terms
and definitions should be referred to the maintenance authority,
for possible amendment and extension of the standard.

7 Status of Annexes

Annex A contains definitions for standard Entity Type terms.
Annex B contains definitions for standard Attribute terms. Annex
C contains cross-reference lists between Included Terms and
Standard Terms.

These annexes are normative in that they shall be used for
transfers of feature conformance levels 1 and 2, as described in
part 1, 5.2.1.2.3. However, use of the terms and definitions
contained in these annexes is optional for feature conformance
levels 3 and 4.
