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
