Building a Great City – Together

IT Best Practises - Enabling City Services from the Ground UP

Bob Gaspirc, Manager GCC

Problems cannot be solved at the same level of awareness that created them.

What makes a great City?

• a great city is one that is known around the world for the quality of life it offers its citizens.

• It’s safe, strong, creative and clean.

• It has a great transit system.

• And leaves no one behind by creating opportunity for all.

Toronto is home to 2.7m people

Toronto is a place of work

Toronto:A place to play

A place to learn and grow

A place of inspiration to

many

Toronto is a major centre of economic growth and

opportunity for Ontario and Canada

Toronto is... Diverse and Multicultural

• Our population continues to grow

• 2.6 million more people will move to Toronto by 2021

12

Who will need 1.6 million more jobs . And

13… 1.25 million more homes

By 2021 we will need 19 additional lanes of expressway capacity to move suburban commuters to jobs in the City and City residents to jobs in the 905 region which cannot be effectively served by public transit.

15

From a simplistic point of view

Uncontrolled growth may ...

• Lead to more air pollution

• Limit our ability to attract new business

16

Globalization and new telecommunication technologies mean ...

17

…can flow into the City … or flow out of it.

We need to grow,we need to grow smarter

Toronto is a caring and friendly cityToronto is a safe, clean, green and sustainable city

Toronto is a dynamic city

Toronto invests in quality of life

What do we want ?

•2011

•6th largest government in Canada

• $11 Billion gross capital/operating budget

•53,000 employed

We Live in a Changing World

Scope of Municipal Services

many services provided round-the-clock Solid waste collection, processing and

recycling Water and wastewater services Emergency services

Policing Fire EMS

Goods and people movement: Transit Roads Sidewalks

Economic development Libraries, parks and recreation Court services Arts, culture and heritage

Tourism promotion Planning and development Building permits Licensing Bylaw enforcement and

inspections Social and health services

Social assistance Homes for aged Child care Hostels Social housing Public health Community support

I&T Opportunities and Challenges

• City growth and need for I&T services is greater than capacity to supply services

• Financial constraints on IT investment may hinder ability to be a catalyst for change and improved service delivery

Agenda

What is IT Service Management/ITIL?Continual Service Improvement ProcessITSM/ITIL Status at the City of TorontoQ & A

25

What is ITSM? IT Service Management

A best practise set of specialized organizational capabilities for providing value to customers in the form of services. IT Service Management takes the form of a set of functions and processes for managing services over their lifecycle.

26

27

ITIL is an approach to ITSM

• Service StrategyDesign, develop, implement service management

• Service DesignDesign and develop services and service mgt. processes

• Service TransitionTransition new and changed services into operations

• Service OperationManage IT Service delivery and support

• Continual Service ImprovementCreate and maintain business value through

better service design, transition and operations

Describes the organisation of IT resources to deliver business value, and documents processes, functions

and roles in IT Service Management

ITIL creates a continual feedback loop

What is CSI?

CSI focuses on maintaining value for customers through the continual evaluation and improvement of the quality of services and the overall maturity of the ITSM service lifecycle and underlying processes.

32

What is CSI?

The primary purpose of CSI is to continually align and realign IT services to the changing business needs by identifying and implementing improvements to IT services that support business processes.

33

Continual Service ImprovementPlan, design, develop, deploy CSI Process:

– Generate and manage process metrics– Formalize Process Maturity

Assessments– Conduct Process Compliance Audits– Implement Process defect tracking and

enhancement repository and procedures

Topographic Database Maintenance Program

Mapping for the Challenges of Today

What data needs to be collected to support the delivery of public services

Service Improvements

• Provide spatial data on a known and dependable schedule

• Provide meta-data, warranty, fit for use statements

• Obtain contractor certificates: QC/QA

• Enable distributed data maintenance

• Coordinate user training regarding use of tools

We need spatially enabled technologies to document events in our Natural and Built Environment

WHAT IS TOPOGRAPHIC MAPPING ?

• A map “view” that represents the horizontal and vertical positions of features

• Distinguished from planimetric by the addition of relief & contours

• 3D mapping introduces the concept of 3D planimetric

How do we model topo features?9 levels of abstraction

74

The OpenGIS® Abstract Specification

Final product

• Timely, relevant, and accurate data needed for your business purposes.

• Accuracy: Truth in advertising

• Content, coverage, completeness, spatial, temporal

• Metadata - (series, layer, feature)


75

What can we see


76

What do we need to map? What band, what time of year

What do you need to see RESOLUTION

• Feature/Object identification• shape, size, height, XYZ, elevation• Typical Use or Display scale• Ground pixel distance

• Variable display scale– Actual shape

– Cell, symbolization

– Generalization

– Skeletonization
