The GIS Mapping component will allow the administrator to define specific areas to alert for both one-time, spontaneous alerts as well as prepared (canned) messages. Upon entering the One-Time message section, administrators will have the option to do one of the following:
- Initiate an alert by selecting one or more groups and/or subgroups
- Click on "GIS Mapping Tool" to open a Java-Script based application to define area to alert
Administrators will have the following two options for defining specific areas:
- Shape-defined Polygon - click line by line to define an area
- Radius-based - Pin is dropped and user defines radius
WENS will classify each user within the system that has an address with a longitude and latitude. This long/lat will determine whether the user is within the defined area and therefore should be alerted.
