FDO provider An implementation of the FDO (page 2062) API that provides
access to data in a particular data store, such as an Oracle or ArcSDE database,
or to a file-based data store, such as SDF or SHP.
feature An abstraction of a natural or man-made real world object. A spatial
feature has one or more geometric properties. For example, a road feature
might be represented by a line, and a hydrant might be represented by a point.
A non-spatial feature does not have geometry, but can be related to a spatial
feature that does. For example, a road feature may contain a sidewalk feature
that is defined as not containing any geometry. In AutoCAD Map 3D, features
are accessed and added to maps using Data Connect (
FDO (page 2062)). See also
attributes or attribute data (page 2055). Compare to drawing objects (page 2061).
feature class For feature data, a schema element that describes a type of
real-world object. It includes a class name and property definitions. Commonly
used to refer to a set of features of a particular class, for example, the feature
class "roads" or the feature class "hydrants." See also
FDO (page 2062), property
(page 2071), schema (page 2073).
Feature Data Objects See
FDO (page 2062).
feature layer A layer in
Display Manager (page 2060) containing feature (page
2063) from a feature source such as SDF, ESRI SHP, or ArcSDE. Feature layers are
brought in using Data Connect. See also AutoCAD layer (page 2056), layer (page
2066),
drawing layer (page 2060), or surface layer (page 2076).
feature source In AutoCAD Map 3D, any source of feature data that has been
connected by means of FDO (page 2062). In MapGuide Studio, one of the two
types of resources created either by loading file-based data or by connecting
to a spatial database. Feature sources are stored in the repository either in SDF
3 format or as database connections and contain raw geometry only. Compare
with
drawing source (page 2061).
FGDC CSDGM Standard Content Standard for Digital Geospatial Metadata.
A standard XML schema for publishing and sharing GIS metadata (page 2069),
released by the United States Federal Geographic Data Committee (FGDC) in
1998. The schema is comprised of seven major sections, each of which contains
several individual data elements and compound elements. Depending upon
the nature of the GIS data, each section, element, and compound element is
mandatory, optional, or conditional (mandatory if applicable).
field A specific category of information in a data file, such as Address or
Diameter. Also called a
column (page 2057). See also table (page 2076).
filtered record A record that matches the conditions of an SQL filter or spatial
filter and is therefore available for selection.
