Tutorial: Import data to create a feature layer | Documentation

Learn how to import data to create a feature layer in a feature service.

ArcGIS hosted feature layer item page showing import and create options.

Importing data is the process of using data management toolsData management tools are ArcGIS software applications and functionality in portal and ArcGIS Pro that can be used by developers to create, manage, and edit content and data such as web maps, hosted layers, and data services for their applications.Learn more in your portalArcGIS portal, also known as a portal, is a website with applications and tools that can be used to create, manage, access, and share geospatial content and data. It supports security and authentication, developer credentials, content and data service management, user and group management, and site administration. A portal can be hosted in Esri's infrastructure or your own infrastructure.Learn more to upload a file to create a feature layerA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more in a feature service. Each file you import becomes a feature layer in the service. If your data contains geometries with attributes, such as a CSV or GeoJSON file, it is imported as a hosted feature layerA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more. A hosted feature layer is also referred to as a feature layerA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more. A feature layer is used to store point, line, or polygon geometries with attributes. After a feature layer is created, applications can access it by IDAn item ID is a unique identifier representing a single item stored, managed, and accessed in a portal, such as a web map, hosted layer, or file.Learn more or URL and then query, edit, and display featuresA feature is a single record, also known as a row, that represents a real-world entity. It typically contains a geometry (point, multipoint, polyline, or polygon) and attributes but it can also contain just attributes.Learn more.

In this tutorial, you use data management tools and scripting APIs to import Trailheads (CSV), Trails (GeoJSON), and Parks and Open Space (Shapefile) files and publish them as feature layersA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more. These layers are used in other tutorials.

Prerequisites

You need an accountAn ArcGIS account is an identity with a user type and set of privileges that can access specific ArcGIS products, tools, APIs, services, and resources.

Steps

Download the data

Download the LA_Hub_Datsets zip file from ArcGIS Online. The zip file contains the following:
- Trailheads.csv
- Trails.geojson
- Parks_and_Open_Space.zip (Shapefile)
Navigate to and unzip the file.

Note
Do not unzip the Parks and Open Space.zip shapefile. You will import this file as is.

Import the Trailheads CSV file

The Trailheads CSV file contains pointA geometry is a geometric shape, such as a point, polyline, or polygon, that contains one or more coordinates and a spatial reference.Learn more data with attributesAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more. Importing the file will create a new point feature layerA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more in a feature serviceA feature service is a data service that provides access to spatial and non-spatial data in feature layers, feature layer views, and tables.Learn more. The import tool attempts to match field names and data types in the CSV file. The four supported field types are: String, Integer, Double, and Date.

Unzip the LA_Hub_Datasets zip file.
- The zip file contains the Trailheads.csv file.
Launch ArcGIS Pro.
- Create a new map project.
- A map with World Topographic Map and World Hillshade basemap layers will be created.
In the Map ribbon, click on Add Data > XY Point Data. The XY Table to Point geoprocessing tool will be displayed.
Set the following information in the XY Table to Point geoprocessing tool:
- In the Input Table input parameter, click Browse and select the Trailheads.csv file.
- Output Feature Class: Trailheads_layer.
- X Field: LON.
- Y Field: LAT.
- Coordinate System: GCS_WGS_1984.

A new point feature class is created and added to the map.

Publish as web layer

Before you can share the feature layer as a hosted feature layer, you will need to enable Allow assignment of unique numeric IDs for sharing web layers option. By default, this option is not enabled. Enabling this option will allow you to assign static IDs to feature layers in your project.

In the Contents pane, right-click the Map > Properties
In the General section, enable Allow assignment of unique numeric IDs for sharing web layers.

With that option enabled, you can now publish the Trailheads, Trails, or the Parks_and_Open_Space layers as a hosted feature layers.

Right-click on feature layer and click Sharing > Share as Web Layer.
- The Share As Web Layer pane will be displayed.
Set the following required information in the General tab:
- Name: The name of the hosted layer
- Provide text for Summary
- Provide text for Tags
- Layer Type: Feature
- Set a location in your organization in Location
Click Analyze
- Any errors or warnings during the analyze process will be displayed in the Messages tab.
Click Publish

A success message will be displayed with Manage the web layer link allowing you to visit the item page details of the hosted feature layer.

Import the required libraries.

You now have three hosted feature layersA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more hosted in your portal. You can access each layer with their service URL or layer IDAn item ID is a unique identifier representing a single item stored, managed, and accessed in a portal, such as a web map, hosted layer, or file.Learn more in your applications. To manage your hosted layer A hosted layer is an item in a portal that contains the properties and settings for a hosted data service or a layer in a hosted data service.Learn more(item) properties and capabilities, visit the Manage a feature layer tutorial.
