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