An analysis of existing production frameworks for statistical and geographic information: Synergies, gaps and integration
The production of official statistical and geospatial data is often in the hands of highly specialized public agencies that have traditionally followed their own paths and established their own production frameworks. In this article, we present the main frameworks of these two areas and focus on the possibility and need to achieve a better integration between them through the interoperability of systems, processes, and data. The statistical area is well led and has well-defined frameworks. The geospatial area does not have clear leadership and the large number of standards establish a framework that is not always obvious. On the other hand, the lack of a general and common legal framework is also highlighted. Additionally, three examples are offered: the first is the application of the spatial data quality model to the case of statistical data, the second of the application of the statistical process model to the geospatial case, and the third is the use of linked geospatial and statistical data. These examples demonstrate the possibility of transferring experiences/advances from one area to another. In this way, we emphasize the conceptual proximity of these two areas, highlighting synergies, gaps, and potential integration. © 2021 by the authors. Licensee MDPI, Basel, Switzerland
Development of regional spatial data infrastructure (SDI) case study in hearth of Borneo
Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Geospatial Technologies.The Heart of Borneo (HoB) initiative was declared on 12 February 2007 in Bali, with purpose to collaborate conservation activities in Borneo Island among Brunei Darussalam, Indonesia and Malaysia. The initiative will join 23 National Parks from three different countries. Concerning the fragmented geographic information from heterogeneous sources, there is a necessity to establish a better management of geographic information among three countries in Borneo Island. The establishment of a Spatial Data Infrastructure (SDI) is one possible solution. In fact, Brunei Darussalam, Indonesia and Malaysia have already developed National Spatial Data Infrastructures (NSDI). The current status of NSDIs is critical for the development of a regional conservation SDI for HoB, but the information for current status of NSDI developments is not available. In this research, the current status of NSDI developments is examined by adopting Reference Model for Open Distributed Processing (RM-ODP). The analysis continues with the identification of required components for developing a regional conservation SDI in HoB. The state of play analysis for the European SDI (INSPIRE) is adopted to investigate available and missing components. On this basis, recommendations for the regional SDI are provided. A prototypical geoportal for regional SDI in HoB is implemented by utilizing GeoNetwork software
Comprehensive measurement framework for enterprise architectures
Enterprise Architecture defines the overall form and function of systems
across an enterprise involving the stakeholders and providing a framework,
standards and guidelines for project-specific architectures. Project-specific
Architecture defines the form and function of the systems in a project or
program, within the context of the enterprise as a whole with broad scope and
business alignments. Application-specific Architecture defines the form and
function of the applications that will be developed to realize functionality of
the system with narrow scope and technical alignments. Because of the magnitude
and complexity of any enterprise integration project, a major engineering and
operations planning effort must be accomplished prior to any actual integration
work. As the needs and the requirements vary depending on their volume, the
entire enterprise problem can be broken into chunks of manageable pieces. These
pieces can be implemented and tested individually with high integration effort.
Therefore it becomes essential to analyze the economic and technical
feasibility of realizable enterprise solution. It is difficult to migrate from
one technological and business aspect to other as the enterprise evolves. The
existing process models in system engineering emphasize on life-cycle
management and low-level activity coordination with milestone verification.
Many organizations are developing enterprise architecture to provide a clear
vision of how systems will support and enable their business. The paper
proposes an approach for selection of suitable enterprise architecture
depending on the measurement framework. The framework consists of unique
combination of higher order goals, non-functional requirement support and
inputs-outcomes pair evaluation. The earlier efforts in this regard were
concerned about only custom scales indicating the availability of a parameter
in a range.Comment: 22 Page
Service-oriented design of environmental information systems
Service-orientation has an increasing impact upon the design process and the architecture of environmental information systems. This thesis specifies the SERVUS design methodology for geospatial applications based upon standards of the Open Geospatial Consortium. SERVUS guides the system architect to rephrase use case requirements as a network of semantically-annotated requested resources and to iteratively match them with offered resources that mirror the capabilities of existing services
Requirements traceability in model-driven development: Applying model and transformation conformance
The variety of design artifacts (models) produced in a model-driven design process results in an intricate relationship between requirements and the various models. This paper proposes a methodological framework that simplifies management of this relationship, which helps in assessing the quality of models, realizations and transformation specifications. Our framework is a basis for understanding requirements traceability in model-driven development, as well as for the design of tools that support requirements traceability in model-driven development processes. We propose a notion of conformance between application models which reduces the effort needed for assessment activities. We discuss how this notion of conformance can be integrated with model transformations
An integrated component-oriented framework for effective and flexible enterprise distributed systems development
Although component-based platforms and technologies such as CORBA, COM+/.NET
and Enterprise Java Beans (EJB) are now widely used for implementation and
deployment of complex systems, the component way of thinking is still
immature. Current CBD best practices, concepts, approaches and methods do not
provide a full and consistent support for various component concepts, and
therefore are not able to provide a full benefit of the CBD paradigm. This
paper defines a new approach to components through an Integrated Component-
Oriented Framework that provides a comprehensive component-oriented support
for enterprise systems development. The framework enables that the same
component way of thinking and the same consistent set of technology-
independent component concepts can be applied in different aspects of
enterprise systems development, from business services to distributed
components
A manufacturing model to support data-driven applications for design and manufacture
This thesis is primarily concerned with conceptual work on the Manufacturing
Model. The Manufacturing Model is an information model which describes the
manufacturing capability of an enterprise. To achieve general applicability, the
model consists of the entities that are relevant and important for any type of
manufacturing firm, namely: manufacturing resources (e.g. machines, tools,
fixtures, machining cells, operators, etc.), manufacturing processes (e.g. injection
moulding, machining processes, etc.) and manufacturing strategies (e.g. how these
resources and processes are used and organized). The Manufacturing Model is a four
level model based on a de—facto standard (i.e. Factory, Shop, Cell, Station) which
represents the functionality of the manufacturing facility of any firm.
In the course of the research, the concept of data—driven applications has emerged in
response to the need of integrated and flexible computer environments for the
support of design and manufacturing activities. These data—driven applications
require the use of different information models to capture and represent the
company's information and knowledge. One of these information models is the
Manufacturing Model.
The value of this research work is highlighted by the use of two case studies, one
related with the representation of a single machining station, and the other, the
representation of a multi-cellular manufacturing facility of a high performance
company
