Setting and Managing Layers

Group Layer

Group layer refers to the group composed of the layers assigned by users themselves, with which it is more convenient to edit and manage the map. If you need to manage multiple layers as a layer, you can group the layers and create a group layer. For example, you have a river layer and an irrigation canal layer, and you can group the two layers and name it Hydrology. A group layer in "Data Content" acts like other layers. However, bedsides the name of the group name, it also displays the layers in the group. Users are allowed to set the properties of each layer in the group, such as visible scale, and so on. Also, you can set the visible scale of the group layer and adjust the order of the layers. If the visible scale of the group layer conflicts with the layers in the group, the system will regard as the setting of the group layer as the priority. In the following section, the ways to set and manipulate group layers will be introduced.
