Layers and the Table of Contents

Layer List

The Layer List is in the Layers panel on left side of the viewer. To open the Layers panel either click on the Layers tab in the lower left corner of the viewer OR click on the Layer List button on the Map tab at the top.

Layers are listed in Groups. Click on the plus to expand a group. The group needs to be checked in order for layers inside it to be visible .

In this example, the New Marsh group is checked on. Layers in the group (New Marsh Boundary 2055 and New Marsh Priobability 2055) can now be checked on and viewed.

Expand as many groups as you like and turn on (check) any combination of layers. Remember that layers draw in order. Layers higher up on the list will draw above and on top of layers below. Layers often overlap so may cover each other up. If this is the case, use transparency or turn the layer off.

Layer Actions

Many layers have a chevron to the right of the layer name in the Table of Contents which opens the Layer Actions menu/panel. The panel contains options like Zoom to full extent (of layer), Zoom to visible scale (of layer), links to Metadata or other related information. At this time, raster layers like imagery do not have the layer actions option. To close the panel, click on the in the upper right corner.

Transparency

Transparency makes a layer partially or fully see-through. Transparency can be adjusted on some layers by moving the transparency slider next to the layer's name.


Layer Information

It is important to be familiar with the layers before you use them for a particular application. Layer information is available for some layers through the Layer Actions panel in the form of guides and metadata. The best place to get information about the layers in the viewer is the Sea Level Rise Effects on Roads & Marshes Layer Information page.
