Part 3: Mobile GIS– GIS on the iPad– Workflows
Introductions
Instructors: Michael Samuel Richel Cebu
Attendees: LWUA Water District Topics or questions you want addressed
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
Value Proposition
