A Case Study on Public Services Web App Helps Locate Valuable Services

A Study about Public Services Web App Helps Locate Valuable Services

Background: Despite economic trends, Lake County continues to receive new residents, as well as the return of many part-time residents, drawn to the warm winters and friendly neighborhoods. But even long term residents may not always be familiar with where to go to get valuable services if they have not used them in the past, or have forgotten where those services are if it has been a while since they were needed.

Case Study on  Public Services Web App

The Issue: Customer service is a priority with Lake County, but it’s not always easy for people to find services they may need when a neighborhood is new or unfamiliar. The information can be spread over a myriad of web sites, yellow pages, and government directories, and phone calls to inquire can get one lost in automated operators, phone trees and voice mail.

Case Study for Medical Web Service for the Automatic 3D Documentation for Neuroradiological Diagnosis

Study about Medical Web Service for the Automatic 3D Documentation for Neuroradiological Diagnosis

Abstract:~ This case study presents a medical web service for the automatic analysis of CTA (Computer Tomography Angiography) datasets. It aims at the detection and evaluation of intracranial aneurysms which are malformations of cerebral blood vessels. To obtain a standardized 3D visualization digital videos are automatically generated. The time-consuming video production caused by the manual delineation of structures, software based volume rendering, and the interactive definition of an optimized camera path is considerably improved with a fully automatic strategy.

Case Study on Medical Web Service

In this case study a web service is presented to generate digital video sequences for 3D documentation automatically. The complete process is split into several subtasks, like defining the camera path, segmentation, detecting the aneurysm and rendering, which are described in Section 2. After a brief overview of the used web architecture in Section 3, some results are discussed which show the usefulness of the presented application in Section 4. Finally Section 5 presents conclusions and ideas for future work. Keep reading…

Case Study on Cascading Web Map Service: Haiti

Study about Cascading Web Map Service: Haiti

Many countries responded to the appeals and launched fund-raising efforts, as well as sending search and rescue teams. By January 26, many organizations had collected sufficient geographic data about Haiti to support local emergency responses. In addition to the many on-line map services deployed for the relief effort, CubeWerx and The Carbon Project deployed a Cascading Web Map Service (WMS) as part of the growing open information network for Haiti.

Case Study on Web Map Service

The service, offered by CubeWerx as a free public resource, helped support relief efforts, rebuilding communications and supported data update operations. The practical benefit of the service is to provide a simple, single access point for any client applications like Gaia, Google Earth and others. CubeWerx WMS service is currently chaining WMS services from New York Public Library, University of Cincinnati, Calit2, Haiti.opensgi.net, CubeWerx and others, as well as imagery from GeoEye and DigitalGlobe from a variety of WMS services. keep reading…

Case Study on Assessing Spatial Distribution of Web Resources for Navigation Services

Study for Assessing Spatial Distribution of Web Resources for Navigation Services

Abstract:~ We present the results of a case study assessing the suitability of the World Wide Web in its current state of the art to provide supporting information for an automated pedestrian urban navigation service. Our experiment simulates an application providing a navigator with navigation aids—routemarks and landmarks—along a path generated by a web service. The instructions generated by this service are tested in human subject testing and evaluated.

Case Study on Web Resources

Introduction:~ Building specialised spatial databases for navigation is a tedious and lengthy process, leading to results requiring frequent updating, as the data soon become obsolete. However, the Internet provides almost whole world coverage with an accompanying unmatched wealth of data. We investigate the representation of the real world phenomena in the World Wide Web (Web), as opposed to the assessment of the Internet real estate geography. This case study illustrates how the spatial coverage and level of detail of the Web content can provide additional information to current pedestrian route planning web-services. Keep reading…

A Case Study on Geospatial Processing Services for Web-based Hydrological Applications

A Study about Geospatial Processing Services for Web-based Hydrological Applications

Abstract:~ River discharge is an important issue to be monitored because of its significant influence on environmental systems, on human lives for water resource exploitation, and hazards related to floods and landslides. In this context, we have designed and developed a web-based Geoportal for hydrological applications that integrates geospatial processing services and web mapping viewers to provide an interactive and user-friendly interface to hydrological modelling experts and scientists.

Case Study on Geospatial Processing Services

Introduction:~ Geospatial web services –web services that serve and process geospatial information for a wide range of territory-based applications– have evolved to become interoperable pieces used to build modular and distributed GIS applications over Internet [18]. They have become key components of Spatial Data Infrastructures (SDI) [15], helping support some the most common requirements of scientific users of information systems such as discovery, access, process and visualization of geospatial datasets. keep reading…

Case Study on Environmental Information

Study about Environmental Information

Abstract:~ Environmental Information and Environmental Information Systems play a major role in environmental decision making. The development of these systems is tightly connected to the environmental awareness of the last three decades. This working paper is a review of the historical development and state-of-the-art of environmental information systems. It focuses on the creation, management and use of Environmental Information Systems (EISs). It is based on the World Wide Web and computerised databases research of the term “environmental information”.

Case Study on Environmental Information

Introduction:~ Environmental Information and Environmental Information Systems play a major role in environmental decision making. This working paper is a review of the historical development and state-of-the-art of environmental information systems. It focuses on the creation, management and use of Environmental Information Systems (EISs). Instead of focusing on the technical attributes of EIS (although they are taken into consideration and analysed), the paper explores those cases where the term EIS was used. The aim of this is to try to understand the reasons for declaring a certain setup of computerised technology and data sets as an “Environmental Information System”. keep reading…

A Case Study for Supporting Strategic Decision ­Making on Climate Change Through Environmental Information Systems

A Study about Supporting Strategic Decision­ Making on Climate Change Through Environmental Information Systems

Overview: Climate change is an imposing challenge faced across all continents. Emerging economies like India are no exception, with climate change impacting not just agriculture but rural ecosystems more broadly and urban environments too (Govt of India 2008). India has some advantages, though, in being able to learn from the mistakes and experiences of the industrialised world, and to take advantage of new technologies; including information and communication technologies (ICTs).

Case Study on Environmental Information Systems

ENVIS is a largely decentralised system consisting of the focal point located in the Ministry of Environment and Forests, and the chain of 76 network partners: a set of institutions throughout the country which host an ENVIS Centre. The physical infrastructure hosting the Centres’ ENVIS ­specific data is a storage area network of India’s National Informatics Centre (NIC), using Internet Information Server as the platform together with MS­Access and MS­SQL 2008 databases. keep reading…

A Case Studies in Geographic Information Systems for Environmental Streamlining

Studies about Geographic Information Systems for Environmental Streamlining

Executive Summary:~ The conclusion of the report details findings that may be helpful to other State DOTs seeking to implement or improve their own GIS4EST applications. Interviewees noted that collaborations, partnerships, and open communication are essential for success, as is the support of upper management. Interviewees also described the importance of training users, as well as the need for quality control protocols and standards. Some agencies recommended a generic, simple design for GIS4EST applications, as this may provide greater flexibility and ease of use, ultimately improving long-term utility.

Case Study on Geographic Information Systems

Introduction:~ Federal Highway Administration (FHWA) published the report “Geographic Information Systems for Environmental Stewardship and Streamlining: An Overview of State DOT Practices.” That report described how eight State Departments of Transportation (DOTs) were beginning to use GIS to promote environmental stewardship while streamlining the environmental review process that the National Environmental Policy Act (NEPA) and other environmental regulations require. Since then, FHWA has continued its support of the adoption and development of GIS applications for environmental streamlining (from here on referred to as “GIS4EST”). As such, FHWA sponsored the case study research presented here to complement its original effort by providing information on current GIS4EST applications from four additional State DOTs along with an update on one of the 2005 case study applications.

A Study on Evolution of Decision Support Systems

A Study for Evolution of Decision Support Systems

Since the first electronic general-purpose computer was put into full operation in the early 1940s, data-processing techniques have been continuously advancing. It was in the late 1950s that many organizations began to utilize transaction processing systems (TPS) or electronic data processing (EDP) systems to automate routine clerical tasks such as payroll, inventory and billing. In the 1960s, we witnessed the emergence of management information systems (MIS) with the development of database management systems for collecting, organizing, storing and retrieving data.

Case Study on Evolution of Decision Support Systems

MIS were developed to extract valuable management information by aggregating and summarizing massive amounts of transaction data and allowing user-interactive managerial queries. The inclusion of simple modelling and statistical methods as a component of MIS permits computer systems to make routine (structured) decisions. keep reading…
