Can a feature dataset contain more than one topology?
A feature dataset can have more than one topology. However, a feature class can only belong to one topology. A feature class cannot belong to a topology and a geometric network. However, a feature class can belong to a topology and either a network dataset or a terrain dataset.
What are feature datasets in GIS?
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 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.
How are feature datasets used in a topology?
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.
Can a user have more than one feature dataset?
For example, users might need to use more than one feature dataset to segment a series of related feature classes to account for differing access privileges between users. Each group has editing access to one of the feature datasets and its feature classes, but no editing access for the others.
Can a feature class be created in a selected dataset?
Cannot create a feature class in the selected feature dataset because the feature dataset is in use by another application/user. Lock request conflicts with an established lock [layer].
How are feature datasets used in geodatabases?
There are additional situations in which users apply feature datasets in their geodatabases: Sometimes, users will organize a collection of feature classes for a common theme into a single feature dataset. For example, users might have a feature dataset for Water that contains Hydro Points, Hydro Lines, and Hydro Polygons.
