What is layer group?

A layer group consists of multiple layers that you would group together based on common attributes. You can group layers with data that fall within the same spatial extent or the same time period, or that are of the same data types, etc.

You can create a new layer group and assign it with layers by using the vMAP Admin Center, please check Manage layer group for vMAP for details. Alternatively, once you have created a layer group from the vMAP Admin Center, when you create a new layer in vMAP Portal there is an option to assign this layer to a layer group.

How do I add a layer to a layer group?

Select the item from the drop-down list on the top navigation bar of vMAP main page to open the Add new layer window. Then you can assign that new layer to a layer group by choosing an option from the Layer group drop-down menu.
