Scene Graph Based Approach for Interoperable Virtual Globes

In this paper, a concept for developing and setting up virtual globes is discussed, which is based on principles of interoperable 3D spatial data infrastructures. Open geospatial industry standards for data and web services are merged with computer graphics technology to create a global coherent framework for accessing and displaying 3D assets. The author discusses how the scene graph concept can be used in a Geoweb environment. The Web 3D Service (W3DS) interface is used for streaming data in a distributed web architecture. Using scene graph data structures for encoding, transmitting, and displaying city- and landscape models imposes new requirements to geospatial analysis. The support of transformations between coordinate reference systems is essential in this context. Scene graph transformations are described in detail including matrix calculations. X3D is discussed as potential exchange format. Experiments were conducted using freely available data of OpenStreetMap and SRTM.

한국표준산업분류에 기초한 공간정보산업의 분류에 관한 연구

공간정보산업의 범위가 모호하여 산업규모와 국민경제에서 차지하는 가치를 조사하기가 힘들었다. 본 연구에서는 한국표준산업분류에 기초하여 공간정보산업 범위와 종류를 명확히 할 수 있는 분류안을 제안하였다. 분류안은 공간정보의 가치사슬에 대응하는 각산업 영역의 역한과 특정을 고려하고 기존 표준산업분류체계를 기초로 하였기 때문에 타 산업분야와 연계성이 높은 공간정보산업의 특정을 반영하고 있다. 향후 본 연구에서 제안한 분류안을 활용하여 공간정보산업 정책을 수립하기 위한 산업 통계정보를 체계적으로 구축할 수 있을 것이다. It is challenging to survey the size and economical value of geospatial industry, because of the vagueness of the industry range. This study suggested a proposed method for the classification of geospatial industry based on Korea Standard Industry Classification, Th proposed method for the classification considered the value added chain of geospatial industry and Korean Standard Industry Classification, Theses considerations reflected characteristics of geospatial industry, Industrial statistics of geospatial industry are expected to be surveyed based on the classification proposed by this study,

공간정보 분야의 원격대학 교육과정 개발

정부는 '국가GIS기본계획'과 관련 법률을 통하여 공간정보 분야의 전문 인력 양성을 위해 다양한 방안을 마련하고 있으며, 특히 온라인 교육에 많은 지원을 하고 있다. 그러나 성인에 대한 재교육 기관으로서, 실용도 높은 온라인 교육을 수행하고 있는 원격대학을 통해서는 공간정보의 교육이 거의 이루어지지 못하고 있다. 이러한 배경에서 원격대학에 적용할 수 있는 공간정보의 교육과정안을 제시하였다. 교육과정은 전문성에 따라 기초, 응용, 심화 단계로 구분하였으며, 개념적 기초 이론을 토대로 시스템 개발 및 구축, 주제도 제작 및 공간자료 구축, 분석 도구의 실습 및 활용 등 세 가지 트랙으로 분류하여 제시되었다. 기초 개념에서부터 최신의 유용한 신기술을 반영하였으며, 모듈화된 구조로 되어 있어 교육 수요의 변화에 용이하게 대응할 수 있도록 하였다. By 'National GIS Plan', various strategies and programs have been carried out for the professional training in the fields of geospatial information. The e-learning can make it possible to develop and manage the adaptable curriculums, to maximize the effect of the practical exercises, and to establish the cooperative systems with the industries. In this study, curriculums of the geospatial fields were developed and suggested for the cyber universities. These curriculums were divided into three stages, fundamentals, applications, and advances, and into three tracks, system development and construction, mapping and geospatial data construction, and practice and application, based on the current demands in geospatial industries. Owing to be the modularized structure, proposed curriculums would be easily adapted and updated to the change of the new demands.

The strategic positioning and configuration of national mapping organisations as enablers of economic and social growth in South Africa

This paper explores the transferability and application of business-driven strategic thinking to that of a public sector context, namely national mapping organisations. These organisations exist throughout the world because the economies of the world require geospatial information to support economic and social growth. As such their strategic positioning within government is of prime importance. In South Africa, however, there is a paucity of knowledge in this regard and consequently triggered the research which forms the basis of this paper.A macro-environmental analysis suggests significant growth opportunities for the South African geospatial industry, fuelled by a micro-industry borne out of the 2010 Soccer World Cup event. A profile description of the characteristics of consequence, boundaries between the private and public the industry and expected changes reflect a large industry which is expanding at a rapid rate but is fragmented and displays a complex network-system of inter and intra-industry relationships. As such it is attracting increasing numbers of competitors but, as an industry, appears to be slow to adjust to technological advancement. An internal analysis of the value chain of the National Mapping Organisation (NMO), the single most important player in the local public sector geospatial industry, reveals significant value creation in its inhouse activities. However, the external deconstructed operations, outbound logistics and procurement processes are not allowing the organisation to realise any benefits from efficiencies it may introduce. Key to achieving efficiencies lies in the human capital, which by all accounts, it is failing to retain.Future strategic thrusts for the NMO have been identified by constructing a SWOT model and by analysing its relative competitive strength. These thrusts were found to concentrate on actions and themes related to staff, communication, marketing, general management, production (cost and capacity) and product (quality and innovation). Interpreting and applying those themes on an interorganisational basis will enable the NMO to best position itself in the industry. In this regard sufficient related strategic fit is evident between the value chains of the NMO, The Satellite Application Centre (SAC) and Statistics South Africa (Stats SA), enabling the NMO to leverage on the sales, marketing and distribution activities of SAC and the financial leveraging capabilities of Stats SA.This paper has presented an example of how delivering an efficient and effective service delivery may be hampered through the inappropriate strategic configuration of South African public sector activities. It is therefore suggested that the government revisits the strategic positioning of public sector organisations engaged in the provision of geospatial information.

An Investigation Into the Methodologies of Producing a Web-based Multimedia Atlas of Victoria

Atlases have traditionally been print-based products predominantly found in schools and libraries, or on the home coffee table. The geospatial industry has always attempted to apply the latest tech...
