Managing Assets
and the
Important Role of GIS
and GPS
Arthur Astarita, Water Resource Specialist

Agenda
Quick review of GPS and GIS
Asset Management (What? & Why?)
– Concepts
– Inventory Attributes (condition, life, replacement
cost)
– Reporting Opportunities
Applying of GIS (Pitfalls)
Tools (Pros / Cons)
Global Positioning System (GPS)
Improving GPS AccuracyDifferential Correction
Geographic Information Systems
GIS vs. CAD
“Large” geographic distribution of assets
versus
One general location with many assets.
Types of GIS software
Freeware GIS– Spreadsheet scatter plots using UTM data
– Google Earth / GRASS
Low Cost GIS– Manifold / Globalmapper
High Cost GIS– ESRI ArcMap
– MapInfo
Tools for Asset Management
What Assets?
Roads / Sidewalks / Manholes / Culverts
Vehicles / Machinery / Equipment
Facilities (water, wastewater)
Forest / Recreational areas / Trails
Aquifers / Watersheds
Computers / Radios / Power Grids
Why Do Asset Management?
Asset replacement decisions based on
best available information.
Information to justify and explain
cash needs
Balance
Sheet
Assets =
Liabilities +
Equity
1. Need a “clean opinion” from an auditor
2. Report value of infrastructure assets
3. Determine cost of deferred maintenance
4. Establishes a good credit rating

Fiduciary duties
“a person to whom property or power is entrusted for the benefit of another”
The primary responsibility falls on operators, the
board of directors and local regulatory officials.
Assets are not Consumed,
They are to be sustained
to provide the
highest service level.

Core Asset Mgmt Questions
1. What is the current state of my Assets?
2. What is my required sustained Level of Service?
3. Which assets are critical for performance?
4. What are the best CIP and O&M strategies?
5. Given the above, what is my best funding
strategy?

GIS Issues for Small Towns
1. Requires specialized equipment, training
2. GIS is compartmentalized
3. No immediate return on investment
4. Too Costly for small government
5. No need for data integration
6. Confidentiality
Specialized
• Designed for desktop use
• Computer power less costly & more available
• User Friendly
Drop down menus
Point and click
File sharing
• Web-based GIS available
Compartmentalized
Collaboration between departments can form:
Planning
Public works
Tax assessor
Code enforcement
Finance
Data and mapping are related
Visualization for officials and citizens
Immediate Return on Investment
• Data already exists on State and Federal sites
• Prior engineering contracts
• Parcel maps already exists*
• Analysis of current and future land use
• Dependent upon data collected, qualified
and, entered
Too Costly
• Pool resources over all town departments
• Form Coalitions with other area towns
• Create programs for local college interns
• Emergency mgmt & homeland security $
Need for Data Integration
• Practicalities for most local governments
• Overcome “silo” departments
• Promote efficiencies between departments
• Land valuations
• Ordinance enforcement
• Budget forecasting
