Workshop Objectives

Understand the basics of GIS Understand GIS Data conversionUnderstand GIS deployment in the

officeUnderstand Mobile GIS out in the field

What is GIS?

Geographic Information System - A System for Managing Spatial (Mappable) Information

More Than Just Software - GIS has Five Major

Components

Applications50%-75%total cost

Hardware

SoftwarePeople

Hardware, Software & People – 2 Options

Option 1 – On-premise install

• Computer Servers – 2 -3• User Computers• User Tablets• High speed Network• GIS Software• Database software• OS Software• Network Software

• IT Administrator• Network Specialist• GIS Administrator• GIS Analysts• Software Programmers

Hardware, Software & People – 2 Options

Option 2 – SaaS (Software as a Service) Model

• Use a SaaS provider for a monthly fee• Computers• Tablets• Internet• No software• No IT Administrator• No Application Experts• Users

GIS Software

GIS Data

• Types of Data- Vector - Attribute Data- Image Data- Other: video, multimedia

• Where Does GIS Data Come From?- In-House: build it yourself (or vendor)- Commercial (license)- Government

Workshop Objectives

Understand the basics of GIS & conversion Types of GIS conversion Build/buy and Technical options Demonstration of conversion methods How to set up a conversion project Contract vs. do-it-yourself conversion Contractor evaluation & selection criteria Conversion costs After conversion, what about updates?

Types of Conversion

1. Land Base

2. Administrative and Reference

3. Utilities

4. Point mapping: people, businesses,

crime, students, health

Land Base Conversion

ParcelsRight of waysStreet centerlinesOrthophotosBuilding footprints

Parcels and Rights-of-Way

Facilities Data Conversion

WaterElectric (distribution, substations,

transmission, street lights)Reclaimed waterSewerStorm drainCATV, telephone, gas, ...

Low Resolution Imagery

High Resolution Imagery

Technical Options for Conversion

Traditional digitizing of paper sources “Heads-Up”: digital landbase + paper maps

- Atlas maps

- Asbuilt maps

Coordinate geometry (“cogo”) Photogrammetry (photo identifiable features, only)

Scanning and auto-vectorizing GPS/Field Survey

AutoCADData Capture

AutoCAD’s limited function OK for data conversion

Low per-seat cost (HW + SW)High productivity for repetitive tasksConvert data to ArcGIS format

Attributedatacapture

Windows input screenUse default and last

record carry-over valueFast, limits operator

error

Scanning and Vectorizing

Capture parcel lines as vectors Capture text as attributes

Scanning andSemi-automatic Vectorizing

Scan and Auto-vectorize

Fast/cheap vectorizing

Problems when spurious lines and text touch lines to be vectorized

Usually requires editing

Using GPS in GIS

1. Types of GPS, their accuracy and applications– GIS system: C-Band, sub-meter accuracy– Single Frequency post processed geodetic grade system– Real-time kinnnematic (RTK): dual frequency system, sub-centimeter

2. Post collection data processing– Download into specified format– Import into some software– Processing: data review checks and corrections; add attributes, reformatting

3. Costs: service vs. do-it-yourself– Equipment– Training– Data management

Typical GIS Project Components

Needs assessment (report) Database design Data capture specifications Budget and cost estimates RFP preparation Pilot project Cost estimates Organization-wide conversion Database maintenance software Enterprise GIS Portal Mobile GIS

Project Management:Needs Assessment

Needs assessment

Project Management: Database Design

Get copies of database design from similar organizations

Review source maps and documents

Edit documents to fit requirements

Vendor prepare database design

Project Management: Data Capture Specifications

Data capture specifications are the rules and standards for converting the maps and source materials into GIS databases.

Graphics Attributes Annotation or text

Project Management: Cost Estimates and Budgets

Get costs of projects for similar types of projects from peers or vendors

Determine unit costs– Number of map sheets– Number of features (parcels, customers, etc.)– Area

Project Management: RFP Preparation

Get copies of RFP’s from similar organizations

Edit document to fit requirements Vendor prepare RFP

Project Management: Pilot Project

In a pilot project, a small area is converted in order to:

Work through technical issues and production work flow Identify any problems with source maps

Finalize database design Finalize data capture specifications Check out the contractor

Quality Assurance / Control

Acceptance criteria 100% audit, sampling Manual checks (paper plots)Programmatic checks (simple/advanced)Client QA and acceptance

Getting Started: Do it Yourself or Contract?

One-time conversion: what do you do with excess staff/equipment?

Determine cost of staff, hardware and software if you do it yourself

Size of project: small project may be OK to do yourself

Accountability: vendors vs. staff

Contractor Selection Criteria

Technical expertise (and focus) Management expertise (and “chemistry”)

– Education: engineering (civil, electrical) Relevant experience

– Company– Project team

References– Call or visit

Cost– balance with understanding of project– Is level of effort sufficient?– basis for cost difference (cost or profit?)

Vendor location

Common Pitfalls in GIS Projects

GENERAL PROJECT MISTAKES Don’t understand the project Rush, Rush, Rush Let quality take a back seat Don’t bother to re-engineer Re-engineer with reckless abandon Let yourself be taken hostage by information

technology Don’t plan for second order effects Don’t bother to train people Forget the fundamentals Let accountability lapse

Smart Water Network Analysis – Enterprise GIS

AGENDA

An Integrated Solution How does the solution benefit the

Customer? What is the Value Proposition Programmed Database Template GIS on the Cloud

How does the solution benefit the customerPre-GIS

Post GIS– Valve Isolation

Value PropositionHow does the customer increase their revenue

using GIS?– Monitors usage, justify rate increases, and better

monitor delinquent accounts

How can the City decrease their expenses?– Reduce water losses,

proactively plan capital improvement upgrades for equipment replacement, don’t wait for failures

Value Proposition

How can the City better serve the needs of their customers?– Using mobile technology,

the City attends to customer calls, faster and more efficiently
