| a. Predefined areaDesc - Similar to (b) but combining with (c), a feature introduced for the ease-of-use. Based on a risk assessment exercise, the users will develop predefined alert area polygons. These polygons will be categorized by the eventType, Incident, Administrative jurisdictions and associated with an area description. During the time of creating a message, when a user defines the eventType, that would trigger for filtering the relevant list of predefine polygons. Additionally, the user may continue to filter by selecting the District and a provide a District name to further filter the predefined polygons. Thereafter, they would select the relevant areaDesc from the present list. Upon selection the polygon or circle shape lat/lon pairs would be automatically populated.
