GIS Data and Geoprocess Modeling for Hydrologic Network Conservation Analysis in a Green Infrastructure Plan

As urban sprawl swallows the areas around cities, planners are looking for alternative methods of development that help to protect and preserve the environment, enhance the lives of residents, and help reduce the skyrocketing costs of maintaining sprawling infrastructure. Green Infrastructure (GI) planning principles have gained in popularity due to their holistic nature and ability to balance preservation and development. A GI plan seeks to identify the critical “green” infrastructure in an area (the environmental resources that we rely on for clean air and water) and proposes complementary development strategies. One plan component of particular interest is the analysis of the hydrologic network, since it is water quality that drives many ecological and environmental planning issues. Over the last 30 years, riparian buffering has emerged as an accepted best practice for the protection and restoration of sensitive hydrologic features. When creating a GI plan, the power of geographic information systems (GIS) is leveraged to help organize, analyze, and display the large datasets needed to synthesize the plan components. The plan components can be quite complex, and the need for solid, well-defined methodologies is great. In response, this thesis proposes a data model that defines the database structure and attributes needed for hydrologic network conservation analysis, based on research conducted during the creation of the Beaver Creek Watershed Green Infrastructure Plan in Knox County, Tennessee. The analysis methodology and some common hydrologic feature buffer practices are described. The specific methods chosen for this project are detailed and a geoprocessing model that generates the datasets necessary to visualize the hydrologic network buffers is presented

A Knowledge Graph Framework for Detecting Traffic Events Using Stationary Cameras

With the rapid increase in urban development, it is critical to utilize dynamic sensor streams for traffic understanding, especially in larger cities where route planning or infrastructure planning is more critical. This creates a strong need to understand traffic patterns using ubiquitous sensors to allow city officials to be better informed when planning urban construction and to provide an understanding of the traffic dynamics in the city. In this study, we propose our framework ITSKG (Imagery-based Traffic Sensing Knowledge Graph) which utilizes the stationary traffic camera information as sensors to understand the traffic patterns. The proposed system extracts image-based features from traffic camera images, adds a semantic layer to the sensor data for traffic information, and then labels traffic imagery with semantic labels such as congestion. We share a prototype example to highlight the novelty of our system and provide an online demo to enable users to gain a better understanding of our system. This framework adds a new dimension to existing traffic modeling systems by incorporating dynamic image-based features as well as creating a knowledge graph to add a layer of abstraction to understand and interpret concepts like congestion to the traffic event detection system

Designing Enterprise Architecture Using TOGAF Architecture Development Model (Case Study: BLC Course Institutions)

Business development must be in line with the development of information and communication technologies to accomplish organizational goals effectively and efficiently. For the educational sector, stakeholders must create and construct information systems that are quick, exact, and accurate regarding business operations in achieving organizational objectives. Information system development must be created in accordance with the organization's strategy to fulfill the organization's information system requirements. BLC Course Institutions recognizes the need of developing an information system that can fulfill the requirements of the organization. The institutions planned to develop enterprise architecture to harmonize the current business strategy in BLC. As the course institute does not have a thorough enterprise architectural design, information system management and business practices are not aligned and lack maturity. So, it has an impact on the service that will be provided to customers. The Open Group Architecture Framework (TOGAF) Architecture Development Method was utilized to create this Enterprise Architecture. Data architecture, application architecture, technology architecture, and creating an implementation plan roadmap are included in enterprise architectural planning in BLC. The process of information architecture determining that was constructed refers to the procedures that had taken place in the educational system administration. The definition process covered in this study includes infrastructure, marketing, academic funding, learning planning, and learning execution. This research produced a blueprint that was utilized to enable integrated business processes. The enterprise architecture created during this stage will be used to assist business operations and accomplish their strategic objectives. The research conclusions indicated that the TOGAF method can be utilized as a tool to design the enterprise architecture of this information system and resulted in a general design architecture model in line with the vision and mission of the BLC and can be used to apply to other tutoring institutions that employ comparable business practices

Coordination of infrastructure development : some international comparisons

This report presents the findings from a desktop review into how governments across a selection of countries coordinate infrastructure development by working with the industry. The selected countries included the UK (Northern Ireland was examined separately from mainland UK), Canada, Germany, Japan and South Korea. The goal is to identify alternative means of coordinating infrastructure development at the government level, with a view to assist the Institution of Civil Engineers to make the case for a more strategic approach to planning and delivery of infrastructure. The need for this report derives from growing complexity in the way infrastructure development programmes are procured, and the shifting role of government from provider of infrastructure development to enabler of the process of delivery. Thus, an opportunity arose to compare alternative arrangements of government coordination. There were similarities of political governance landscape between the investigated countries regarding strategies of infrastructure delivery. Differences exist however in the way resources are allocated and decisions made regarding infrastructure development. A potential for greater transparency and collaboration between public and private sector was identified. In Germany, for example, local governments enjoy a great deal of autonomy in defining infrastructural requirements, even though the definition of requirements has to align with high-level planning principles at the regional, national and European levels. Delivery of infrastructure development is devolved to the local governments working with a range of stakeholders from both the public and private sectors with funding provided by regional allocations. By contrast, infrastructure development is coordinated by a single high-level government department Canada, Japan and South Korea. The make-up of this department varies across the three countries, with subtle differences in the roles and responsibilities of each constituent part. Nonetheless, the benefits of such an approach include a whole-systems view in decision-making and a somewhat simpler, more transparent way of funding allocation. Furthermore, in the case of Japan and South Korea, resources can be more effectively channelled towards advancing research and development related to infrastructure development capacity and more clarity in terms of skills development. The UK, on the other hand, has a fragmented approach in addressing infrastructure development, with a continuously evolving system of government departments and agencies having some form of influence on determining infrastructural requirements. In order to redress some of the challenges with such fragmentation, the situation in Northern Ireland differs slightly with the formation of a Strategic Investment Board Limited charged with overseeing infrastructure programmes, making delivery more transparent

Challenges in Creating a Disaster Resilient Built Environment

With the increase in occurrences of high impact disasters, the concept of risk reduction and resilience is widely recognised. Recent disasters have highlighted the exposure of urban cities to natural disasters and emphasised the need of making cities resilient to disasters. Built environment plays an important role in every city and need to be functional and operational at a time of a disaster and is expected to provide protection to people and other facilities. However, recent disasters have highlighted the vulnerability of the built assets to natural disasters and therefore it is very much important to focus on creating a disaster resilient built environment within cities. However the process of making a disaster resilient built environment is a complex process where many challenges are involved. Accordingly the paper aims at exploring the challenges involved in building a disaster resilient built environment. Paper discusses the findings of some expert interviews and three case studies which have been conducted in Sri Lanka by selecting three cities which are potentially vulnerable to threats posed by natural hazards. The empirical evidence revealed, lack of regulatory frameworks; unplanned cities and urbanisation; old building stocks and at risk infrastructure; unauthorised structures; institutional arrangements; inadequate capacities of municipal councils; lack of funding; inadequacy of qualified human resources; and corruption and unlawful activities as major challenges for creating a disaster resilient built environment within Sri Lankan cities. The paper proposes a set of recommendations to address these prevailing concerns and to build a more resilient built environment within cities

Seeing the invisible: from imagined to virtual urban landscapes

Urban ecosystems consist of infrastructure features working together to provide services for inhabitants. Infrastructure functions akin to an ecosystem, having dynamic relationships and interdependencies. However, with age, urban infrastructure can deteriorate and stop functioning. Additional pressures on infrastructure include urbanizing populations and a changing climate that exposes vulnerabilities. To manage the urban infrastructure ecosystem in a modernizing world, urban planners need to integrate a coordinated management plan for these co-located and dependent infrastructure features. To implement such a management practice, an improved method for communicating how these infrastructure features interact is needed. This study aims to define urban infrastructure as a system, identify the systematic barriers preventing implementation of a more coordinated management model, and develop a virtual reality tool to provide visualization of the spatial system dynamics of urban infrastructure. Data was collected from a stakeholder workshop that highlighted a lack of appreciation for the system dynamics of urban infrastructure. An urban ecology VR model was created to highlight the interconnectedness of infrastructure features. VR proved to be useful for communicating spatial information to urban stakeholders about the complexities of infrastructure ecology and the interactions between infrastructure features.https://doi.org/10.1016/j.cities.2019.102559Published versio

Creating Change through Arts, Culture, and Equitable Development: A Policy and Practice Primer

Across the nation, artistic and cultural practices are helping to define the sustainability of urban, rural, and suburban neighborhoods. In the design of parks and open spaces; the building of public transit, housing, and supermarkets; in plans for addressing needs for community health and healing trauma; communities are embracing arts and culture strategies to help create equitable communities of opportunity where everyone can participate, prosper, and achieve their full potential. And artists are seeing themselves -- and being seen by others -- as integral community members whose talents, crafts, and insights pave the way to support community engagement and cohesion."Creating Change through Arts, Culture, and Equitable Development: A Policy and Practice Primer" highlights both promising and proven practices that demonstrate equity-focused arts and culture policies, strategies, and tools. The report describes the role of arts and culture across the nine sectors below. Within each policy chart there are goals, policies, and implementation strategies that can help achieve communities of opportunity. These policies have yielded such outcomes as: support for Native artists in reservation-based cultural economies, the creation of a citywide cultural plan, engaging low-income youth of color in using digital media, and efforts to address redevelopment, employment, food access, and environmental justice

Aligning enterprise risk management with business strategy and information systems

Business leaders recognise effective risk management as one of the main success drivers for enterprises. Even though the Enterprise Risk Management (ERM) concept has evolved significantly in the past years, in the aftermath of recent economic crises it became evident some of its critical challenges still need to be addressed. The review of subject literature led to a conclusion that current ERM approaches failed to protect enterprise value in turbulent and risky market conditions. Therefore, this paper aims to provide a conceptual analysis of the most common ERM practices and frameworks, in order to identify their shortcomings and areas requiring development. It is further aimed to provide guidance to business practitioners in implementing more integrated and effective Enterprise Risk Management (ERM) solutions. This research recognises the importance of aligning ERM programmes with business strategies, and with consolidated Information Systems. A “New Approach ERM Model” is developed as guidance for a successful alignment of ERM with enterprise business strategy, and for an effective adaption of Information Systems to requirements of ERM programmes. The “New Approach ERM Model” steers risk management initiatives and strategies in the same direction, and consequently allows enterprises to improve organisational effectiveness, increase shareholders value, and gain competitive advantage in the market
