The built-in Map Editor is a powerful feature of Synoptic Panel visual that allow you to manage, preview and edit maps interactively, without leaving the visual. Each section is described in detail below.
To start using Map Editor, it is essential to have at least one map loaded into visual. When Importing Maps directly from visual by click on the Add Map button, the Map Editor will be automatically opened and the first map loaded previewed.
If you already have a map loaded in the visual, you can open the Map Editor by clicking on the Edit icon 
in the visual Toolbar.
Map Editor is available only in the Editing View. If you are in Reading View, you need to switch to Editing Mode to access the Map Editor. Moreover, it is not available if you are using the Map URLs field well.
