The Geographical Maps style Map allows the user to create live geographical maps based on the Google Maps API. A menu listing of all available Maps can be accessed by selecting Views -> Maps from the opCharts menu bar.
Creating a New Geographical Map
1. A Geographical Map must be created before it can be used or added to a Dashboard. To create a new Map, Click the "+" icon from the Maps screen (Views -> Maps).
2. Next, select Geographical Map from the Map Type drop-down located in the top-left corner.

Link to Map
If set, the Link to Map option will open a new URL when the link is clicked. You can select either a Map on the current server, or by selecting Custom use any URL (even to other software/sites). This is especially powerful - allowing you to drill down from a top-level abstract diagram to more in-depth levels of detail.By default the Link to Map / Custom option opens the target in the current browser window. However, you can force opCharts to open the link in a new tab/window by enclosing the link URL in double quotes and following it with target=_blank i.e "http://someserver.com//en/omk/opCharts/dashboards/myawesomedashboard" target=_blank
Once the node is added it may be moved around the Map by left-clicking and dragging it to position.

As of opCharts version 3.2.2 you can Zoom Lock the maps preventing them from zooming in and out when you scroll your mouse wheel. This option can be toggled on or off by the check box as shown in the screenshot below:
Geographical Maps clustering
As of opCharts version 3.2.6 Geographical maps will cluster items on the map that are too close together. You can get more information on the devices in the Cluster by clicking on the 12/12 icon as displayed in the image below. In this example, the Cluster Icon is indicating that there are 12 out of 12 reachable devices.
To disable this feature you can set opcharts_maps_geographical_clustering to 0 in /usr/local/omk/conf/opCommon.nmis
