Water Distribution System Network
Calhoun County Rural WaterBy Steve Klaas
MAY 17, 2013GEOG 424: VECTOR BASED GISDR SHUNFU HU, SIUE
Geometric Network Created To Model Water Distribution System Network for Calhoun County Rural Water (CCRW)
Personal Geodatabase, feature dataset, feature classes, domains, subtypes, Geometric Network, and Utility Network Analyst all used to create network
Smart Utility Network allows parts to be disabled in order to determine effects on the rest of the system, such as a boil order for a broken water line
Creation of a Water Utility Network for CCRW
Introduction
Study AreaCalhoun County, Illinois is the
peninsula shown to the right of the arrow, between the Illinois and Mississippi RiversData Sets
Data Sources
Digital Orthophoto Mosaicfrom USDA NCRS Geospatial Portal
Only the central portion of Calhoun County was included for this project
Data Sets
CCRW GeodatabaseContains all GIS Data Used in Project
including Feature Classes within WaterDS Feature Dataset
Methodology
Geodatabase DomainsCoded Values Used To Provide Legal
Values for Each Field Type to Maintain Data Integrity
Methodology
WaterDS Feature DatasetContains all Features Classes Used In Building
Geometric Network: Water Lines, Customers, Valves, And Water Source
Methodology
Feature ClassesEach Feature Class Was Given
Categorical Subtypes with Default Values for Certain Fields
Methodology
Geometric Network
Includes all features in WaterDS Feature Dataset. Geometric Network
creation allowed further analysis to be performed through use of Utility Network AnalystMethodology
DigitizingFeatures such as Customers,
Water Lines, and Valves Digitized Using Digital
Orthophotos as a ReferenceMethodology
