Create a web map

What is a web map?

A web map is an item in a portal that contains the properties and settings for a map. The item includes properties such as the initial map extent, basemap, data layers, and all styling configurations. To create and save a web map you use Map Viewer or ArcGIS Pro. These tools allow you to interactively design and configure a map. After creating a web map, you can use it to build custom mapping applications or low-code/no-code applications.

You use a web map when you want to:

• Create a map that you can share with other users and applications.
• Interactively design and style layers in a map.
• Configure popups for data layers in a map.
• Display a map in an application built with ArcGIS Maps SDKs.
• Securely store and access a map in a portal.
• Remotely configure a map at any time to change your application.

Web map configuration

You can create and configure how a web map will be visualized. Some of the key types of configurations you can make to a web map include following:

How to create a web map

The general steps for publish an item:

1. Set the basemap layer

A basemap, also known as a basemap layer, is a layer that provides the overall visual context for a map or scene. It typically contains geographic features and labels for continents, lakes, administrative boundaries, streets, cities, and places.

To create a new web map, you can use Map Viewer or ArcGIS Pro. These tools allow you to design and configure a map interactively and then save it in a portal.

2. Add data layers

To display data in a web map, you can add hosted feature layers in the Map Viewer or feature layers in ArcGIS Pro.

3. Save the web map

After you create a web map, you can save it. Saving the map will create a new item and you can access the map in an application. You can also set the security of the item to the appropriate sharing level.
