Data Model: Feature Class Types

    Table of contents
    1. 1. Topics in this section

    Each feature class consists of one feature table. This table has a fixed basic structure, but you can create additional columns (attributes).

    Basic Structure: Every feature has an identifier FID (feature identifier) that is unique for each database schema ( industry model ).

    The feature geometry is saved in Oracle Spatial (standard attribute GEOM).

    For more information, refer to the Oracle Spatial Users Guide and Reference.

    Feature Class Types

    Description

    Attribute

    For attribute tables (features without geometry).

    Centroid

    For centroids. A special point associated with a polygon that is defined by line strings. A centroid is surrounded by the features of a line string feature class that builds the polygon.

    Examples: parcels, land use.

    Collection

    For features with any geometry (lines, point, or polygon). Normally, a feature class contains features of only one geometry type. In a collection feature class, you can store features with different geometry, which means that you can store point features, line features, and so on in one single feature class.

    Compound LineString

    For polylines. A group of two line string feature classes.

    Compound Polygon

    For areas. Built as a group of a line string and a polygon feature class.

    Dimension

    For dimensioning. Consists of related tables: Dimension feature class <name>, line string feature class <name>_L, label feature class <name>_TBL with line string <name>_HL and point feature class <name>_P.

    Label

    For text. Is related to a parent feature class and therefor can only be created from feature class level.

    LineString

    For polylines.

    Polygon

    For (closed) polygons. Consists of arcs as well as lines or polylines.

    Point

    For points.
