What is a geodatabase feature dataset?
In the geodatabase, feature classes can be standalone or they can be organized into larger units called feature datasets. A feature dataset stores feature classes that have the same coordinate system and the same spatial extent, meaning they occupy the same geographic area.
What is a feature class?
Feature classes are homogeneous collections of common features, each having the same spatial representation (such as points, lines, or polygons) and a common set of attributes (for example, a line feature class for representing road centerlines).
What is the difference between a feature and feature class?
Feature Layer: A layer that references a set of feature data. Feature data represents geographic entities as points, lines, and polygons. Feature Class:In ArcGIS, a collection of geographic features with the same geometry type (such as point, line, or polygon), the same attributes, and the same spatial reference.
What is a file geodatabase feature class?
The file geodatabase is stored as a system folder that contains binary files that store and manage geospatial data. It is available at all ArcGIS license levels and functions in the same fashion on Windows and UNIX (Solaris and Linux) operating systems.
How do I add a feature class to a feature dataset?
Creating a feature class in a feature dataset
- In the Catalog tree, right-click the feature dataset in which you want to create a new feature class.
- Point to New > Feature Class.
- Type a name for the feature class.
- Choose from the drop-down list the type of features that will be stored in this feature class.
What is a feature dataset?
3 days ago
A feature dataset is a collection of related feature classes that share a common coordinate system. Feature datasets are used to facilitate creation of controller datasets (sometimes also referred to as extension datasets), such as a parcel fabric, topology, or utility network.
What is a feature class vs shapefile?
Shapefiles are a type of feature class. A feature class is a collection of common features that share geometry, attribute fields and in GIS, a spatial reference.
Why use a feature dataset in your geodatabase?
Feature datasets are used to spatially or thematically integrate related feature classes. Their primary purpose is for organizing related feature classes into a common dataset for building a topology, a network dataset, a terrain dataset, or a geometric network.
What is GIS feature?
A “Feature” is a single entity in GIS that has both geometry and attribute data. The attribute data can be just a single ID number or it can encompass all kinds of other data about the feature.
What are geodatabases feature classes?
Each feature class is a collection of geographic features with the same geometry type (point, line, or polygon), the same attributes, and the same spatial reference. Feature classes stored in geodatabases can be extended as needed to achieve a number of objectives.
How do I create a geodatabase dataset?
To create a feature dataset, right-click the target geodatabase in the Catalog pane, point to New, and click Feature Dataset . The Create Feature Dataset geoprocessing tool opens. Type a name for the feature dataset in the Feature Dataset Name text box.

How are feature classes created and stored?
Feature classes are created and stored in a geodatabase either as stand-alone objects or organized into a feature dataset. Feature datasets are used to spatially or thematically integrate related feature classes.
