Use ArcGIS ProArcGIS Pro is a professional desktop GIS application that can explore, visualize, analyze, and manage 2D and 3D data.Learn more to import the shapefile and create a feature layer.

Unzip the Santa Monica parcels zip file.
- The zip file contains the Parcels_Public.shp 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 > Data and select Parcels_Public.shp file.

The Parcels_Public.shp file is added as a feature layer to the map.

The feature layer will look something like this:

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.
1. In the Contents pane, right-click the Map > Properties
2. In the General section, enable Allow assignment of unique numeric IDs for sharing web layers.
With that option enabled, you can now publish the Santa Monica Parcels polygon feature layer as a hosted feature layer.
1. Right-click on feature layer and click Sharing > Share as Web Layer.
  - The Share As Web Layer pane will be displayed.
2. Set the following required information in the General tab:
  - Name: Santa Monica Parcels
  - Summary: Parcels in the Santa Monica Mountains
  - Tags: Santa Monica Parcels
  - Layer Type: Feature
  - Set a location in your organization in Location
3. Click Analyze
  - Any errors or warnings during the analyze process will be displayed in the Messages tab.
4. 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.

The styled layer will look something like this:
