A Space is a map view of projects and spatial data in your portfolio. You can have access to more than one at a time.
Open a Space from Home
Home lists your Spaces, even though it isn't one itself. Find yours there, and Giraffe opens it into its own map view.
Open Giraffe. You land on Home.
Select Spaces from the dropdown, then find the Space you want. Type into the search box to find it by name, or switch between gallery and table view.
Click Open to the row of the Space to open it.
Other ways to open a Space
The project switcher in the top bar: click it, then search or scroll to find your Space under the Spaces header.
If you're inside a project and have a favorite Space set, click the Space icon in the breadcrumb trail to jump straight back to it.
Set your favorite Space from the account menu. See Select Default Space.
