What is a feature dataset in a geodatabase?
What is a feature dataset in a geodatabase?
A feature dataset is a collection of related feature classes that share a common coordinate system. Create a controller dataset, such as a topology, terrain dataset, network dataset, utility network, or parcel fabric.
What is a replica geodatabase?
Geodatabase replication allows you to create copies of data across two or more geodatabases such that changes to the data may be synchronized. Replica creation involves the user defining the data to replicate from a source geodatabase, then running a process to create replicas.
What is the difference between a feature class and a feature dataset in a geodatabase?
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 feature dataset and feature class?
• 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)
What are the benefits of a feature dataset?
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?
What is replication in ArcGIS?
Geodatabase replication is one of the data distribution workflows available in ArcGIS Pro. Geodatabase replication is built on top of the traditional versioning environment and distributes all or parts of your data in a manner that allows any data changes to be synchronized across two or more geodatabases.
How do I create a replica in ArcGIS?
Create a one-way replica
- Start ArcGIS Pro and open an existing ArcGIS Pro project, or begin without a template.
- In the Catalog pane, right-click an existing geodatabase connection and click the Distributed Geodatabase context menu.
- Select Create Replica .
What’s 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 a raster dataset?
A raster dataset is any valid raster format organized into one or more bands. Each band consists of an array of pixels (cells), and each pixel has a value. A raster dataset has at least one band. ArcGIS supports more than 70 different file formats for raster dataset, including TIFF, JPEG 2000, Esri Grid, and MrSid.
What are features of a dataset?
Each feature, or column, represents a measurable piece of data that can be used for analysis: Name, Age, Sex, Fare, and so on. Features are also sometimes referred to as “variables” or “attributes.” Depending on what you’re trying to analyze, the features you include in your dataset can vary widely.
What is geodatabase replication and how does it work?
Define the data to replicate—Geodatabase replication allows you to replicate some or all of the datasets in your enterprise geodatabase. It also allows you to define what features or rows to replicate using filters and relationship classes.
Can I change the metadata of replicated datasets?
However, changes to the metadata are not applied during replica synchronization. When replicating data through the Create Replica wizard, you can choose to change the name of replicated datasets. This is done in the Advanced Create Replica Options dialog box of the wizard.
Can I distribute my data to different geodatabases?
Available with Standard or Advanced license. Various workflows require you to distribute your data to different geodatabases and synchronize changes made to the data in each geodatabase. The following provides a guide to help you determine how best to use distributed data, geodatabase replicas, and synchronization for your system.
How do I prepare my data for replication?
The following steps should be considered when preparing data for replication: Geodatabase replication allows you to replicate all datasets or a subset of datasets in your geodatabase. To be replicated, these datasets must meet the following requirements:
