Using Custom Layers

Custom Layers

Existing and Custom Layer: Users can now access Layers in one place in the EVAC system. These layers consist of both the existing EVAC layers and Customer Layers that allow users to integrate ESRI/WMS (web mapping service) layers, called “Custom Layers”, that overlay the EVAC map.

Getting to Layers:

  1. The Layers icon can be found in the top right corner of the Genasys EVAC web screen. Once the Layers icon is selected, the list of custom layers is show via a box with each section presented as a drop down. See Figure 1 with numbers corresponding to their function.
    1. TRAFFIC LAYERS – Traffic Layers are standard EVAC layers corresponding to the Road Closures, Traffic Control Points, and Live Traffic data housed directly in the EVAC system. This is the same Traffic Layers preexisting in the system, just a new location to control the filters
    2. EVACUATION – Evacuations are standard EVAC layers corresponding to the Arrival Points, Critical Evacuation Facilities, and Equipment data housed directly in the EVAC system. This is the same layers preexisting in the system, just a new location to control the filters
    3. FIRES - Fires are standard EVAC layers corresponding to the Red Flag Warnings, Heat Detection, Active Fire Perimeter, and Active Fire ingested by the EVAC system. This is the same layers preexisting in the system, just a new location to control the filters
    4. CUSTOM LAYERS - Layers will be sorted into two sub menus:
      1. Those layers added by the user themselves (i.e.
