' Mass Notification System GIS has proven to be a valuable technology for community alerting and public outreach , such as Reverse 911 . Reverse 911 is inherently a GIS application as spatial selection and analysis are fundamental for the effective utilization of Reverse 911 . Please refer to the Sherriff Department ' s Needs Assessment for a complete description of this application . Department Support for Water, Wastewater and Storm Water Modeling The Utilities Services Department already utilizes Haestad Methods ' WaterCAD as a stand- alone application for water and distribution network modeling . However, modeling is not currently being performed with GIS data . Haestad Methods ' WaterCAD can be integrated .. with ArcGIS 9 through an ODBC connection . Complete and accurate information is needed before these applications can be utilized . The Utilities Services Department should consider migrating from WaterCAD to Haestad Method ' s WaterGEMS , which will take advantage of the digital water network built within ArcGIS . In addition , the Department could utilize Haestad Method ' s SewerGEMS and FlowMaster applications for wastewater modeling and Haested Method ' s StormCAD , FlowMaster, CulvertMaster, and Pond Pack for Storm Water modeling . All of these applications work with the ArcGIS platform . WaterGEMS WaterGEMS allows users to display, edit , run , map, and design water models from within the GIS environment : users can view the results of the simulations as native GIS maps or with traditional Haestad Methods modeling tools . WaterGEMS also provides cross-product functionality provided by the core Unified Data and Object Model architecture . With WaterGEMS, users can : ,. .. _ .- - - View and edit multiple - a. .
