Using the polygon mode

Polygon drawing mode allows you to draw polygons on the map which can be used for a number of reasons, for example to identify your drive area, create a target location, and to determine which data lies inside or outside the polygon, this can be helpful for example when you are analyzing where a target phone was based on timing advance or geo-location data.

To use polygon drawing mode, hover over on the top-right of the map, click then select Polygon from the menu. Left-click on the map to start drawing your polygon; left -click to create another point; double left-click to complete your polygon. Right-click inside the polygon to display a menu that provides you with options of how you can use the polygon and the data inside and outside the polygon.
