What is Enterprise Architecture?
“Enterprise Architecture (EA) is the business of
architecting the enterprise.”
The goal of the process is to take the business
strategy and translate it into effective change of
the enterprise
The scope of enterprise architecture includes the
enterprise’s people, processes, information, and
technology and their relationships to each other
and the external environment

Why is Enterprise Architecture Needed?
Enterprise Information
systems and business
processes are complex and
will become increasingly
complex in the future.
As system complexity
increases, the costs to build
and maintain those systems
increase and take more of an
organizations resources in
time, money, and personnel.

Why Segment Architecture?
Enterprise Architecture provides “big picture” view
across the organization
Segment Architecture focus on specific areas of the
business and is more detailed and results-oriented
Improve program performance and better customer
(citizen) service
Perform operations more efficiently and effectively

EA Segment Identification
A scalable and repeatable process for architects to engage business
stakeholders and deliver value to business areas
Helps to establish clear relationships between Strategic Goals,
Detailed Business and Information Management
Requirements, and Measurable Performance improvements.

Why Geospatial in EA ?
Geospatial information is used in a majority of
business settings in and outside of Municipality
Geospatial information and services are not
addressed consistently within and between
organizations
Interoperability among providers and consumers
of Geospatial data and services requires a common
understanding of semantics and functional
capabilities

Tehran Municipal Geospatial EA
• Tehran has 22 districts,
each of which is
administered by their
own district mayors who
report to the mayor of
metropolitan Tehran.
• Each district divided to
some regions. The
number of regions is
dependent to the size of
the district and some
other social parameters.

Business Architecture
Goal 1: Improve Municipality decision making by
incorporating location based approaches, data, tools and
knowledge into business processes.
Current Efforts include:
Inserting Location-Based analysis into Municipality business
workflow
Solutions Architecture Guidance to Map Geospatial
Components

Data Architecture
Goal 2 : Provide Municipality, its organizations, and the
public with the geospatial data they need to carry out their
business processes and make environmental decisions.
Efforts should include:
Establish a Urban Geospatial Data Policy in Tehran Municipality
Geospatial Metadata “template”/Business Rules/Architecture
Builds on Metadata Standards
Collaboration on Base Map Production

Application Architecture
Goal 3: Provide Municipality staff, organisations, and the
public with applications and web-services to access,
manage, use, analyze, present, and interpret geospatial data
to conduct business and make environmental decisions.
Efforts should include :
Reusable open and interoperable tools
Portal Development Efforts
Developing Geospatial Web Services for Data Access

Technology Architecture
Goal 4: Design and implement an enterprise wide
technical infrastructure that supports access, use,
management, and delivery of distributed geospatial data,
applications, and Web services in a seamless manner.
Current Efforts include :
Geospatial needs incorporated into the EA
IT/ICT Road Map
Geospatial Tools used in Portal Development

Governance
Goal 5: Establish an effective governance structure for
setting priorities for geospatial investments, coordinating
geospatial efforts, and communicating how geospatial data
and technologies are used within the Tehran Municipality.
Efforts should include :
Geospatial needs incorporated into the EA
GIT Work Group/Steering Committee
Budget/Strategic Planning linkage

Municipal Geospatial Enterprise Architecture provided
understanding of how geospatial approaches, data, and associated
technologies should be incorporated into the Tehran Municipality
enterprise architecture.
It includes three constructs:
• Develop an infrastructure of staff and services that work together
to provide geospatial resources in support of the Municipality’s
business.
• Identify the Municipality’s business activities that depend on location
and support them with appropriate geospatial data and services to
improve performance.
• Incorporate geospatial functionality into traditional business
Municipality’s activities not previously optimized to support geospatial
information and services.
