What is feature dataset?

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 are feature domains in GIS?

Domains and subtypes are components of feature layers and feature classes that can be used to constrain or define fields in your datasets. ArcGIS Insights supports using datasets and fields that have a domain or subtype defined.

What are domains in geodatabase?

A domain is a set of rules that define permitted values for an attribute. They are used to constrain data values in order to ensure data integrity. A domain is defined in a geodatabase as a unique entity and can be applied to any attribute in any feature class within the geodatabase that contains the domain definition.

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.

When would you use a feature dataset?

Feature datasets are used to spatially or thematically integrate related feature classes….Use feature datasets to organize spatially related feature classes into a common dataset:

  1. To Add a Topology.
  2. To Add a Network Dataset.
  3. To Add a Geometric Network.
  4. To Add a Terrain Dataset.

What is feature class and feature dataset?

• Feature dataset – collection of feature classes (e.g., transportation contains roads, railroads, airports) organized into a group, all of which share a common coordinate system. • Feature class – a collection of features with the same type of geometry: point, line, or. polygon (e.g., roads)

Why we need to define domain in a geodatabase?

Using domains helps ensure data integrity by limiting the choice of values for a particular field. Attribute domains can be shared across feature classes, tables, and subtypes in a geodatabase.

What is the difference between a feature dataset and feature class?

A feature dataset stores feature classes that have the same coordinate system and the same spatial extent, meaning they occupy the same geographic area. While all features in a feature class must have the same geometry type, the same is not true for feature datasets.

What is the difference between feature dataset and feature class?

How do I create a feature dataset?

Note:

  1. In the Catalog tree, right-click the geodatabase in which you want to create a new feature dataset.
  2. Click New > Feature Dataset.
  3. Type a name for the feature dataset.
  4. Navigate to the spatial reference you want to use.
  5. Use Modify if you want to change any parameters in the coordinate system you’ve chosen.
