Basemaps

A Basemap draws below the other layers in a map. To change the basemap, click on the Basemap Gallery icon. Choose from a long list of options. Don't know what to choose? Try the Imagery Hybrid, Topographic, or the Dark or Light Gray Canvas.

TIP!  Although not technically listed under the basemap button, any of the Elevation or Imagery layers can be turned on in the Layer List and function as a basemap.

Overview Map

The Overview Map icon is a tiny arrow in the lower right corner of the viewer. Click  to open and show the map and click  to close it.

Layer List

In the map, the Layer List is open by default on the right side of the viewer when using a large screen device.

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

Expand as many groups as you like and turn on () 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.

Reorder Layers

The map allows changing the order of layers. Locate the 6-dot reposition () symbol next to a layer. The mouse turns to a cross-hair indicating that clicking and dragging the layer will move it to a different spot on the list. Layers can also be moved outside of their home group and/or into a different group.

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.

Options

Each group item and layer has three-dots on the far right which opens the Options menu. Some layers types have more options than others.

TIP! The Options menu is not accessible (it is grayed out) if the layer is not visible (be sure the layer AND the group are both checked).

• Transparency

Transparency makes a layer partially or fully see-through.

The Legend is automatically displayed to the right of the map next to the Layers List tab when using a large screen device. Click the tab to view the legend, which will include the symbology for the layers that are visible (checked on) in the map.

Find My Location

The Find my location button adds your current location to the map and zooms to it. The blue dot is your location. Note that the location could be influenced by the internet provider and/or the accuracy of the basemap. It also requires location to be enabled on your device.

Measure

Select the Measure icon and then choose to measure distance () or measure area (). Once a measure tool is selected, the mouse turns to an orange circle.

Click on the map to start the measure. Notice that the orange and white line or orange fill is measuring as the mouse moves. Click again to add vertices and continue until the line or shape is complete. Double-click to finish. The measurement is shown on the map and in the Measurement window. The units can be changed at any time.

TIP! While in the middle of measuring, you can makes changes to the measurement units, turning layers on and off, moving the measurement window, and more.

Scale Bar

The scale bar is in the lower left corner of the map. The feature compares a map distance to the actual distance in real life. The number shown is a ratio between the distance on a map and the corresponding distance in the real world. The more zoomed-out the map is, the larger the the number.
