What is Geographic Information System?

A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. GIS can show many different kinds of data on one map. This enables people to more easily see, analyze, and understand patterns and relationships.


Rapid Notify can help you deliver emergency notification alerts to precise locations quickly and effectively. Our Geographic Information System (GIS) provides targeted mass notification inside specific, user-defined geographic areas. This can include e-911 data and other commercially available residential and business phone numbers.


GIS users have multiple options for defining specific alert delivery areas, including:
Zoom In, Zoom Out, Pan – Zoom to a specific area such as a neighborhood in a city.
Create Lists by Drawing a Shape– Click line-by-line to define an area with a polygon shape or select a center point to define a circle radius, and much more.
Powerful Selection Tools– Select contacts street-by-street or use the “Buffer Tool” to select contacts just outside of a pre-defined area.
Save Map-Based Lists – Create and save a specific contact list based on a one-time map selection.
Select Contacts by Proximity to Map Features – For example, select all contacts along a train track or flood control channel.
