    Spatial Data Infrastructure (SDI) is the base for the development and implementation of geospatial direction in many countries. SDI is made of framework of geographic data, Standards, Policies, Tools, Geographical information systems (GIS), Technical Infrastructure, Metadata and legal procedures. GIS being one of the components in the Spatial Data Infrastructure is important for dissemination of geospatial information and services. In Malaysia the Spatial Data Infrastructure or Geospatial Data Infrastructure is known as the Malaysia Geospatial Data Infrastructure (MyGDI). MyGDI enables the evolution of geographical information Systems in Malaysia Public Sector. Over the years many GIS applications have emerged through the development of MyGDI at the federal, state and the local authority levels. GIS application can be categorized into different disciplines such as public safety, disaster management, transportation, traffic control, tracking, health, environment, natural resources, mining, agriculture, utilities and many more. The aim of the paper is to discuss on how MyGDI has facilitated the evolution GIS in Malaysian Public Secto

    In the article publications have been analyzed and summarized on this topic: studied the experience of implementing building information models and geographic information models for administrative and economic management of transport infrastructure facilities on the example of the regional airport activity. After the stage of collecting geospatial data from various sources and sensors, the data is imported into CAD-systems or GIS-systems. Different software products are used to work with both of these models. The processes of data organization in the process of creating building information models and geographic information models differ to some extent. The issues of integration of such models are not yet fully addressed and need to be addressed. In the process of integration of spatial data, solutions to the integration of semantics, topology, formats and standards of geospatial data are needed. An important task is to develop and study the experience of creating software modules that allow you to integrate BIM-models into geographic information systems. Based on the research, it is established that the current area of research is the development of technologies that allow the generation of information from BIM and GIS to create a more interconnected infrastructure. The integration of BIM and GIS information to create a spatial data infrastructure (SDI) is a perspective direction

    Geographic Information Systems (GIS) have become an indispensable tool in many fields of study and research. GIS is useful for choosing sites, targeting market segments, planning infrastructure facilities and responding to emergencies. GIS is internationally used for the educational sector in different aspects such as planning schools allocation and managing educational resources. This thesis investigated the spatial distribution of schools in Abu Dhabi with respect to population density and service areas, generated prospective locations for constructing new schools based on the current and future demand using multi-criteria decision rules, developed a road network system that helps in finding shortest and best routes between schools and houses of students and Teachers and developed a user friendly-Interactive GIS based School Finder Tool. In the course of this research a comprehensive GIS database was also developed for all the 71 schools of the Abu Dhabi Island. Entire GIS analysis and tools development were executed using ESRI\u27s ArcGIS 9.2 software. In addition this research has given good insight into the role of geographic information systems (GIS) in the school\u27s education program, planning and Management as teachers may also have opportunities to learn about GIS and apply it to their instruction. The thesis observed that the GIS activities at Abu Dhabi schools are small scale, however GIS industry initiatives, UAE government and higher education institutions outreach, and emerging national standards are signaling an increasing adoption of GIS activities by the schools and there is also a need for specific GIS software designed for teaching and educational purposes

    The Marine Safety Umbrella Operation (MSUO) facilitates the cooperation between Interreg funded Marine Safety Projects and maritime stakeholders. The main aim of MSUO is to permit efficient operation of new projects through Project Cooperation Initiatives, these include the review of the common protocols and procedures for Information Technology (IT) and Geographical Information Systems (GIS). This study carried out by CSA Group and the National Centre for Geocomputation (NCG) reviews current spatial information standards in Europe and the data management methodologies associated with different marine safety projects. International best practice was reviewed based on the combined experience of spatial data research at NCG and initiatives in the US, Canada and the UK relating to marine security service information and acquisition and integration of large marine datasets for ocean management purposes. This report identifies the most appropriate international data management practices that could be adopted for future MSUO projects

    Bridging the Gap Between Traditional Metadata and the Requirements of an Academic SDI for Interdisciplinary Research

    Get PDF
    Metadata has long been understood as a fundamental component of any Spatial Data Infrastructure, providing information relating to discovery, evaluation and use of datasets and describing their quality. Having good metadata about a dataset is fundamental to using it correctly and to understanding the implications of issues such as missing data or incorrect attribution on the results obtained for any analysis carried out. Traditionally, spatial data was created by expert users (e.g. national mapping agencies), who created metadata for the data. Increasingly, however, data used in spatial analysis comes from multiple sources and could be captured or used by nonexpert users – for example academic researchers ‐ many of whom are from non‐GIS disciplinary backgrounds, not familiar with metadata and perhaps working in geographically dispersed teams. This paper examines the applicability of metadata in this academic context, using a multi‐national coastal/environmental project as a case study. The work to date highlights a number of suggestions for good practice, issues and research questions relevant to Academic SDI, particularly given the increased levels of research data sharing and reuse required by UK and EU funders

    The Next Edition of IHO-S-57 (4.0): A Primer

    Get PDF
    The International Hydrographic Organization (IHO) is an intergovernmental consultative and technical organization that was established in 1921 to support the safety of navigation and the protection of the marine environment. IHO Special Publication 57 (IHO S-57) is the IHO Transfer Standard for Digital Hydrographic Data. It is the standard to be used for the exchange of digital hydrographic data between hydrographic offices (HOs), and for the distribution of hydrographic data to manufacturers, mariners and other data users (e.g., GIS). It was developed so that the transfer all forms of hydrographic data would take place in a consistent and uniform manner. To date, S-57 3.0/3.1 has been used almost exclusively for encoding Electronic Navigational Charts (ENCs) required for ECDIS. However, S-57 is intended to support all types of hydrographic data. In order to do so, S-57 Edition 3.1 needs to expand in order to accommodate new requirements. This “Primer” explains what is planned in regard to the next edition of IHO S-57 (Edition 4). In particular, it provides a brief description about process required to align with ISO geospatial standards and the benefits to be gained. Included is an explanation about the scope of activity of the TSMAD S-57 Edition 4 Sub-WG, and how others may contribute to the process
