How to open and edit a Web Map in ArcGIS Pro
Web maps and web layers can be added from your active ArcGIS Online portal to ArcGIS Pro. In this article, you'll add a web map to a project and make further changes to the web map in ArcGIS Pro. You'll then save your changes to your ArcGIS Online portal.
We will use a Web Map that we created in a past article: "How to create and share a Web Map in ArcGIS Pro". This Web Map is stored into our ArcGIS Online portal content (My Content)
Software requirements:
- ArcGIS Pro 3.2.2
- ArcGIS Online or ArcGIS Enterprise account with sharing privileges
1 - Open or create a new ArcGIS Pro project. We opened a project named Web_Map_IC_Article.
2 - Open the Catalog pane (View tab), click the Portal tab. Under Portal, make sure the My Content tab is selected.
The web map and web feature layer appear at the top of the content list (after any folders you have created). If you don't see your content (you actually need to have some content), click the Menu button and click Refresh.
By default, the items are sorted by their last modified date. You can sort them if needed.
3 - In the Catalog pane, right-click the web map that you would like to open and click Add and Open.
We chose to open our web map named Indigenous_Communities_SLR. The web map is added to the project.
4 - Hover over the map view tab of your default map and click Close. Your web map is now the only open map.
5 - You will confirm that the map and its layers are hosted in your portal. In the Catalog pane, click the Project tab. Expand Maps.
Your project may contain one or more maps. The link icon indicates a web map.
6 - In the Contents pane, click List By Data Source. The source of the map layers (except the basemap) is the web feature layer form your portal.
7 - On the Quick Access Toolbar, click Save Project.
8 - You will now modify your web map in ArcGIS Pro.
Anyone in your organization can add the web map to ArcGIS Pro. As the map owner, you can change the web map in ArcGIS Pro and save your changes to the web. When you do so, other users of the web map receive a notification that a newer version of the map is available.
We'll make two changes in our project:
- change the symbology in the Indigenous Communities layer.
- add another NOAA Sea Level Rise Inundation level using ArcGIS Online portal.
If you open a web map owned and shared by someone else, you can make changes to the map and save those changes in your project. If the web map owner subsequently saves new changes to the web map, and you accept the update, any changes you have made to the web map version in your project will be overwritten. If you need to preserve those changes, do not accept the update. Alternatively, before accepting the update, make a copy of the web map in your project or save it as a map file.
9 - In the Contents pane, under your layer (Indigenous Communities for us), right-click the symbol to open the color palette. Click a different color. We chose Dark Amethyst.
10 - Now, we are going to add the NOAA 2-foot Sea Level Rise Inundation tile layer. You can add another layer from your ArcGIS Online portal as well by following the steps below.
11 - Open the Catalog pane (View tab), click the Portal tab. Under Portal, make sure the ArcGIS Online tab is selected.
12 - We are going to search for Sea Level Rise EPA. Press the Enter key.
13 - We right-click one the NOAA 2-foot Sea Level Rise Inundation tile layer and select Add To Current Map.
The NOAA 2-foot Sea Level Rise Inundation tile layer has been added to the project.
In the map above, it is evident that numerous indigenous communities in Louisiana would face submersion with a 2-foot Sea Level Rise.
14 - Now we are going to share our map. On the ribbon, click the Share tab. In the Manage group, click Save Web Map.
- Click Save web map to update the existing web map.
- Click Share as new web map to open the Share As Web Map pane. You can share a new web map to examine the features that may be altered or lost before committing the save to the original web map.
15 - On the Save web map window, choose one of the options. We clicked on Save web map.
The Save Web Map pane appears. In the pane, parameters that can't be changed are disabled. By default, the Archive the last updated web map check box is checked. An archive copy of the web map in its current state in the portal (using the purple symbol color for the Indigenous Communities locations) will be preserved in case we need to revert to it.
16 - At the bottom of the pane, under Share with, confirm that the map is still shared with your organization.
17 - Under Finish Saving, click Analyze.
Analyzer errors and warnings, if any, appear on the Messages tab. Errors prevent sharing and must be fixed. Warnings may affect web map performance or display but don't prevent sharing. Right-click a warning or error to take corrective action.
18 - Click Save. When the map is shared, a success message appears at the bottom of the pane.
The process may take some time depending on network traffic or connection stability. If it fails, you may need to share it again.
To monitor the sharing process more closely, click Jobs under Finish Sharing to open the Job Status pane.
19 - On the success message, click Manage the web map to open a web browser window or tab. Sign in to your ArcGIS organization if necessary. The map's item details page appears with the Overview tab selected at the top of the page.
Now you can open, explore, and modify the web map in Map Viewer if needed.
