1. Publish tile cache service
First publish the tile cache service that will serve as the base map.
2. Create a group
The default group in Portal is Featured Maps and Apps. Here you can create a new group for sharing basemaps.
3. Add basemap
Add a base map and save it as a Webmap
. You can also add it here by searching.
If you need to set it as the default basemap, you need to share it with the previously created group.
4. Share and set default
Share to the group, and then in the organization's settings, map can set the group's webmap as the default basemap.
Select and set the corresponding group:
After that, you can have your own default basemap in MapViewer, or you can switch between your own multiple basemaps, but all basemap service coordinate systems and slicing schemes are required to be consistent.
5. The problem that the basemap image cannot be displayed
Solution:
-View the item id corresponding to the webmap-
search in portal, search in C:\arcgisportal\content\items
You will find that the thumbnail folder is missing:
refer to the normal items with thumbnails:
create pictures by yourself, or copy pictures from other services. Such problems generally occur when copying and deploying existing slices.
