Define a new dataset

To create the schema (field structure) for a new empty feature layer in a feature service, you can define a new dataset. To do so, you use data management tools to define the fields and schema. You typically use this process when you need to publish an empty feature layer that your applications will populate with features. For example, data entry applications or field applications. After it is created, you can manage the service settings with a hosted feature layer (item) in your portal.

Use this approach when you want to:

• Dynamically specify the field structure of an empty feature layer in a feature service for your applications
• Store points, polylines, and polygon in a feature layer
• Store non-spatial data as a standalone table
• Store string and numeric data in fields
• Store attachments with features
• Store and access features in different formats (JSON, GeoJSON, or PBF)

Types of datasets

When you define a new feature layer, you need to determine the data type that best fits your data, workflow, and application needs. ArcGIS supports four different dataset types:

How to define a new dataset

The general steps to define a new dataset are as follows:

1. Sign into a data management tool with your ArcGIS account:

   • Go to ArcGIS.com and sign in to your portal (ArcGIS Location Platform or ArcGIS Online)
   • ArcGIS Enterprise portal (ArcGIS Enterprise)

2. Use the tool to define the fields and schema for your feature layer. This creates the following:

   • Hosted feature layer: A new item in your portal to manage the item properties and service settings.
   • Feature layer and feature service: A new feature layer in a feature service for the data.

   The most common next step is to add data to the new feature layer. You can use tools such as the Map Viewer or ArcGIS Pro to add, update, and delete features.
