Heard of GIS Have a GIS system Planning on getting a GIS system Dreaming of a GIS system

What is GIS GIS at CAW Quick Demon (if there is time, maybe)

Geographic Information System An organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information An organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information.

At CAW GIS is … a computer based tool for analyzing and mapping water distribution & related features… NOT JUST FOR PRETTY MAPS The technology provides a flexible set of TOOLS to perform diverse functions in our organization…

GIS is used to query data, share data, reduce redundant record keeping and provide a analytical tool to help staff MAKE BETTER, MORE INFORMED DECISIONS …it is a efficient way to communicate complex information by providing a VISUAL CONCEPT OF YOUR DATA

Support for Water Hydraulic Model Create Thiessen polygons to sectionalize the service area. Create an elevation grid, using Spatial Analyst Assignment Proximity feature. Create a Geocode Address for extracting and summing average day consumption. GIS programs codes to batch process the data and automatically populate required data fields. GIS allows for automated data extraction and avoids tedious and laborious manual task. Reduces time and human resources it would take to calculate and assign the demand and elevation values in the water hydraulic model. GIS reduces like task from months to days and even hours

Supporting the Hydraulic model Demands and Elevation calculations

Work is reduce from months... …to days or even hours

Establishing serviceable areas.... Sample of Model Displaying Streets, Lots, Pipes, Max Fire Flow Available, Max Service Elevation,Contours, and Boundary

Color code by fire flow, pressure, residual pressure, demand, maximum service elevation, velocity, headloss, or any number of other factors.

An analysis of matching the service records with the GIS address file. Results: Service records have a number of old or incorrect address. The GIS address file have missing addresses.

The initial cost to implement GIS is high… Return on investment is worth it... Fairfax County, VA The county reduced the number of crews from 16 to 10 and had an estimated annual savings of $200,000. Martin County, FL The parcels were reassessed and generated an additional 3.5 million in tax revenue for the county. Lucas County, OH Saved $10,000 per year on map maintenance and recaptured 570 man-hours that are devoted to serving the public. City of Tucson, AZ Over a five year period, the water district expects to realize a net return from the investment in GIS of $5,356,942 due to increase staff efficiency.
