Cadastral spatial information closely related to ownership of people is potentially very valuable information. As 3D cadastre has been actively discussed to reflect realistic living territory and legal relationship in recent years, it is highly expected to be created added value before long using that information. However, in aspect of visualization that performs an important function for decision making by facilitating intuitive thinking about spatial information, systematic solution has not been suggested to visualize the cadastral spatial information on a map with existing 3D spatial information. For that reason, in this paper, visualization method was proposed to integrate the cadastral spatial information with the existing information effectively. Requirements for 3D cadastral spatial information system were drawn based on literature review, and then specific visualization method was established by constructing user scenarios. Research results of this paper are highly expected to be applied to the integration work with the existing 3D information on a spatial information open platform.

다양한 데이터에 대해 정확한 분석이 요구되는 분야가 증가하면서, 데이터를 효율적으로 가시화하는 방법에 대한 요구도 증가하고 있다. 분석에 효율적인 가시화란 데이터의 특성을 잘 표현함으로써 분석가가 데이터를 직관적으로 이해할 수 있도록 도와주는 것을 말한다. 이를 통해 데이터를 분석하는 시간을 줄이고 정확한 결과를 얻는데 도움을 준다. 본 논문에서는 가스 배관을 검사하기 위한 Geometry 피그（PIG:Pipeline Inspection Gauge)와 MFL 피그로부터 얻어지는 데이터를 다양한 방법으로 가시화하고 분석에 효과적인 가시화와 시스템의 구현에 대해 다룬다. 각 피그의 다중 센서를 통해 얻어온 데이터를 Line graph, Pseudo Color Image, 3D Surface, Polar View, 3D Pipeline View와 같은 다양한 방법으로 가시화하고 view들 간의 동기화 및 사용자 지정 view 배치를 통해 빠르고 정확한 분석을 가능하게 하는 여러 가지 방법에 대해 설명한다.

본 연구에서는 국내 3차원 공간정보 데이터 표준 포맷인 3DF-GML 데이터 모델의 데이터 구조 분석을 수행하였다. 또한 3DF-GML 데이터 포맷과 기존 공간정보 데이터 포맷과의 전환 가능성을 검토하여 기존에 구축된 공간정보간의 연계 및 전환 가능성을 분석하였다. 이러한 분석 결과를 바탕으로 Shape파일, 3DS 데이터와 3DF-GML 데이터 간의 포맷 변환 도구를 개발하였으며, 변환된 3DF-GML 데이터의 유효성 검증을 위한 3DF-GML 가시화 도구를 개발하였다. 본 연구에서 제시한 3차원 공간정보 데이터 변환 및 가시화 도구는 국내 3차원 표준 포맷인 3DF-GML의 변환 및 가시화 기능을 제공해줌으로써, 다양한 응용 분야에서 3차원 공간정보 데이터 사용의 활성화에 크게 기여할 수 있을 것으로 기대한다.

This study presents an application of GIS technologies to construct the graphic user interface for 3-dimensional exhibition of the results obtained by ocean hydrodynamic model. In coastal management studies, GIS provide a receptacle for scattered data from diverse sources and an improvement of the 3D visualization of such data. Within the frame of a GIS a variety of analytical, statistical and modeling tools can be applied to transform data and make them suitable for a given application. A 3D hydrodynamic model was driven by time-dependent external forcing such as tide, wind velocity, temperature, salinity, river discharge, and solar radiation under the open boundary condition. The Jinhae Bay was selected as a case study. Here, we have used GeoMania v2.5 GIS software and its 3D Analyst extension module to visualize hydrodynamic model result that were simulated around the Jinhae Bay.

The behaviors of combustion-induced internal flows of SRM equipped with fin-slot grain and submerged nozzle are very complex and diverse. Cold air-flow tests for 2D and 3D scale models of SRM have been done in order to specify the visualization method to analyze particular internal flow patterns such as roll-torque inducing flow. Swirl flow induced by asymmetric vortical tubes also has been visualized through employing various light source and recording directions.

Data size of moving current GIS great exponentially from 2D to 3D and the processing speed becomes slow thereby and user's real time rendering request is growing. Have problem that time and expense to process data of bulky quantity produce constraint condition of the processing speed. third dimension processing skill, virtual reality processing skill etc. and third dimension GIS about space data of bulk much overmuch to materialize. In this paper DEM data that acquire from satellite or aviation solve these problem embody virtual city in web save topography information that visualization to 3D visualization by VRML, and use modelling tool and acquire 3D campus information for building and road. 3D information acquired this to express texture and natural gifts that have truth stuff more to thing through near texture mapping work 3D imagination illustration of web based embody can.

Cable is very essential material for ship operation as connecting element for whole electrical facilities of ship. The material cost and installation man-hour increment caused by re-installation is unavoidable if cable route has some problem. The purpose of this study is to suggest methods to implement the cable visualization functionality for verifying whether cable route is accurate or not in design phase. This functionality is conducted by representing color of 3D model for strong visibility by refer to textual cable routing information. The electrical engineer can provide cable route information more accurate and on time for cable installation department. As a result, the material cost and installation man-hour reduce due to decreasing ratio of re-installation.

Recently, flood damages have increased with heavy rainfall and typhoon influences, and it requires that visualization information to the flood inundation area of downstream in dam discharge. This study developed 3D GIS system that can visualize flood inundation area for Namgang Dam downstream. First, DEMs extracted from NGIS digital maps and IKONOS satellite images were optimized to mount in iWorld engine using TextureMaker and HeightMaker modules. And flood inundation area of downstream could be efficiently extracted with real-time flooding water level using Coordinate Operation System for Flood control In Multi-reservoir (COSFIM) and Flood Wave routing model (FLDWAV) in river cross section. This visualization information of flood inundation area can be used to examine flood weakness district needed in real time Dam operation and be applied to establish the rapid flood disaster countermeasures efficiently.
