<p><strong>Abstract.</strong> In the 1990’s, the International Maritime Organization (IMO) adopted the International Hydrographic Office’s (IHO) S-57 performance standards for Electronic Navigation Charts (ENC), which enforce standardized content, structure, and format. The IMO also revised its Safety of Life at Sea (SOLAS) chapter V regulations to require Electronic Chart Display and Information Systems (ECDIS) onboard certain SOLAS class vessels, starting from 2018. These systems allow for navigating with ENC data, which has several advantages over paper charts; however, many mariners still prefer traditional paper or raster charts. Through the feedback of key stakeholders such as local pilot associations, it has become apparent that the preference for raster or paper charts is due to the inclusion of non-critical S-57 land features. These S-57 land features, which are typically not added to ENC products, such as roads and elevation contours, can supplement navigational positioning systems by providing visual references, particularly when other landmarks (e.g., spot elevations on major topographic features) are not present on the ENC. Moreover, charting roads on ENC products can be useful for locating water access points. This paper discusses the addition of roads and land elevation contours to NOAA’s re-schemed ENC suite in an effort to supplement currently charted marine features and land features crossing over water. General cartographic guidelines have also been developed for the representation of these features through ENC scales (i.e., usage bands 3 to 5). Additionally, this paper includes a discussion on the benefits and challenges of incorporating publicly available land transportation data versus traditional sources on ENC products.</p>

In 1989 the International Maritime Organization (IMO) published its Provisional Performance Standards (PPS) for ECDIS (Electronic Chart Display and Information Systems) and asked member governments to assess these standards and submit their findings to the Sub-Committee on Safety of Navigation. IMO intends to finalize the standards in 1993.

Electronic navigational charts (ENCs) are geospatial databases, compiled for the operational use of Electronic Chart Display and Information systems (ECDIS) according to strict technical specifications of the International Hydrographic Organization (IHO). ECDIS is a GIS system designed for marine navigation according to the relevant standards of the International Maritime Organization (IMO). The international standards for ENCs and ECDIS, issued by the IHO and IMO, cover many aspects of the portrayal of ENCs in ECDIS but do not specify or recommend map projections. Consequently, in some cases, the unjustified employment of map projections by the manufacturers has caused certain functional drawbacks and inadequacies. This article reviews, evaluates and supplements the results of earlier studies on the selection of map projections for the depiction of ENCs in ECDIS and proposes a reasonable set of suitable projections with pertinent selection/implementation rules. These proposals took into consideration that ECDIS users (navigators) are not GIS experts or professional cartographers and consequently, the proposed election/implementation rules have to be simple and straightforward.

Information Systems Implementation

While there has been some considerable investment in information systems implementation and usage in the public sector, success has often been limited. Attempts by researchers to address this situation has been diverse and often inconclusive. A publication by the MIS Quarterly journal offers some direction. The study, which focused on information systems development (ISD), highlighted the need to explore how mutual understanding among key stakeholders is created, or the extent to which they have a shared conception of the ISD project, and further how such mutual understanding is changing, develops, or deteriorates over time. On the tenets of the study, this chapter attempts to chart a path for future research in interoperable financial management systems implementation and usage in the public sector. It presents a viewpoint that establishes the need to explore the creation and sustenance of mutual understanding between stakeholders in the implementation and usage of interoperable or integrated financial management systems in the public sector.

In this article certain pillars as basics are presented being necessary to develop Web services (W3C, 2007) supporting human resource (HR) processes like assessing, hiring, modeling information systems, staffing, and so forth; by the help of these Web services. Current HR information systems in general do not adequately support tasks related to cross-organizational or global skills and competence management. In the following, the topic is presented which relates to knowledge management especially to “communities of practice,” as well as related topics such as e-skills and ICT (information and communication technologies) professionalism; the latter currently being broadly discussed by experts in Europe. HR managers of a company or an organization are challenged through the need to formalize skills requirements and to continuously monitor the skills demand inside the company. Obtaining ICT skills are not a one-time event. Technological change advances at a high speed and requires that skills need continually to be kept up-to-date and relevant (The European e-Skills Forum [ESF], 2005). During the last years, new concepts have emerged which intend to empower learners and individuals to steer learning processes to a large extent on their own. Learning objectives tend to be increasingly individual in character (ESF, 2005). In this context, providing an appropriate infrastructure which supports the continuing professional development (CPD) of employees is today a key issue.CPD processes require a respective infrastructure encompasses besides qualifications, skills/competence frameworks and body of knowledge, as well required standards for competence, skills, and appropriate career and development services. Standards encompass educational and industry-oriented performance standards which in turn are expressed preferably through a common language as competence and skills standards. The governance and administration of the CPD process require the availability of flexible and personalized certification services which offer the formal validation of individuals’ learning achievements independent of where and how they were acquired.
