본 논문에서는 첨단 ICT기반의 다양한 기술들을 이용하여 미래형 지도에 대해 제안한다. 미래형 지도는 현실세계에 존재하는 유무형의 사실과 현상에 대한 이해와 해석을 통하여 다양한 형식으로 결과를 표현하고 사용자 참여형의 새로운 모습으로 발전될 것으로 전망되고 있다. 향후 지도는 경제, 산업, 일상생활에 필요한 정보의 수집, 처리, 활용, 분석, 배포 및 공유가 실시간으로 이루어지는 새로운 패러다임을 지향하는 지도 형태로 발전할 것으로 예상된다. 이러한 관점으로 본 논문에서는 지도, 데이터베이스, 공간분석의 개념을 기반으로 현실공간의 정보를 디지털화하여 실시간 개인 맞춤형 콘텐츠를 제공하고, 시계열 데이터의 표현을 특징으로 하여 사회, 경제, 문화 등 모든 분야의 거시 현상을 분석 및 예측하여, 미래창조경제를 선도할 수 있는 '신 패러다임 맵'에 대한 개념을 정립하고 그에 따른 핵심 기술들을 기술한다.

지하공간에는 다양한 구조물들이 있고 그 구조물들의 지하공간 데이터는 지하공간통합지도 관리 시스템(IUGMMS)에서 3D 데이터로 관리되고 있다. 작업자는 준공도서 제출 프로그램으로 변경된 지하공간 데이터를 반영한 통합지도 전체를 IUGMMS에 전송하여 갱신하고 있다. 그러나 통합지도 파일의 크기가 크기 때문에 전송하고 갱신하는 시간이 지연되는 문제점이 있다. 본 논문에서는 변경된 통합지도와 IUGMMS에 저장되어 있는 통합지도에서 공간특성정보를 각각 구하고 비교해서 변경된 지하정보 데이터가 있는 통합지도만 추출하여 전송하고자 한다. 실험 결과, 기존 방법은 전송하려는 통합지도의 영역이 넓을수록 통합지도를 전송하는 시간과 갱신하는 시간이 파일 크기에 비례하여 증가하였지만, 제안한 방법은 변경된 지하공간 데이터가 포함된 통합지도만 전송하기 때문에 전송 시간이 짧았고 갱신하는 시간도 짧았다. 그 결과 변경된 통합지도를 전송하고 갱신할 때 발생하는 시간의 지연을 줄일 수 있었다.

This study examines the limitations of existing crime mapping that relies mainly on reported crime data, suggests a crime mapping method based on experts' and users' assessments of a neighborhood environment as an alternative approach, and conducts a case study on a real-world site by applying the suggested approach. According to the results of the case analysis, while the areas adjoining arterial roads with heavy pedestrian traffic were shown as high crime risk areas in the crime map based on actual reported crime data, the areas adjoining local roads with low pedestrian traffic were high-risk areas in the crime risk area map based on experts' and residents' evaluations. This study makes a contribution to the field in that it demonstrates the detailed application process of crime risk area mapping according experts' and residents' evaluations, compares the results with those of an existing crime map, and finally shows that the former can function as a complement to the latter.

As NGIS project has been implemented in 1995 and effectiveness of spatial information increased, Digital maps serve several purpose in administrative, living, and industrial fields. But, Digital maps have many differences with real world information and difficulties in application of managing urban facilities due to high update cost and long generation period. In this study, We suggest methodology to update a building layer of digital map in urban area as regenerating a building layer by detection of changed buildings in the existing digital map anf extraction using LIDAR data and Aerial images, more easier to acquire data and available to guarantee accuracy. Experimental results are expected to applied for constructing 3D urban model in a broad expensive urban area.

A new model for the construction of a sonar map in a specular environment has been developed ad implemented. In a real world where most of the object surfaces are specular ones, a sonar sensor suffers from a multipath effect which results in a wrong interpretation of an objects's location. To reduce this effect and hence to construct a reliable map of a robot's surroundings, a probabilistic approach based on Bayesian reasoning is adopted to both evaluation of object orientations and estimation of an occupancy probability of a cell by an object. The usefulness of this approach is illustrated with the results produced by our mobile robot equipped with ultrasonic sensors.

A fundamental technology of UGV(Unmanned Ground Vehicle) to perform a given mission with success in various environment is a path planning method which generates a safe and optimal path to the goal. In this paper, we suggest a local path-planning method of UGV based on the binary map using world model data which is gathered from terrain perception sensors. In specially, we present three core algorithms such as shortest path computation algorithm, path optimization algorithm and path smoothing algorithm those are used in the each composition module of LPP component. A simulation is conducted with M&S(Modeling & Simulation) system in order to verify the performance of each core algorithm and the performance of LPP component with scenarios.

The paper presents a sonar based map building method. The environment is a room or area inside a building, which is composed of four types of geometric primitives(corners, edges, cylinders, and walls). We also assume the environment can be modeled into two dimensional map in terms of planes(walls), points(corner and edge), and circle(cylinder). In a real world where most of the object surfaces are specular ones, a sonar sensor suffers from a multipath effect which results in a wrong interpretation of the location of an object. To reduce the effect and uncertainty, the method employs a simple thresholding technique for extracting circular arc features called regions of constant depth(RCD) from scanning sonar data. The usefulness of the approach is illustrated with the results produced by sets of experiments.

Many countries have recently been expanding efforts for low-carbon global economy to solve the problem of global warming. Development and research for various types of new reusable energy is on the rise throughout the world. The most promising source of energy is the solar photovoltaic energy and the government take an initiative to establish both short-term and long-term policies to develop the solar energy potential resource map. The solar energy and industrialize area researched by GIS methods for optimum site for solar power transfer system. This study attempts to address the hot issue of the development and suitability of the solar photovoltaic energy site using GIS spatial analysis. We need to analyze and describe the solar technology, green energy policies and the energy market trend of the field.

This study is the part of development of information management system for irrigation facilities. It describes the design and prototype presentation of WISIF(Web-based geographic Information System for Irrigation Facilities). WISIF manages the IFDB(Irrigation Facilities DataBase) and offers geographic information of irrigation facilities from IFSDB(Irrigation Facilities Spatial DataBase) through World Wide Web. GeoMedia Web Map software of Intergraph is used to offer geographic information to users. GeoMedia Web Map generates vector format, so called ActivCGM. The file generated in ActiveCGM format can be downloaded fast since its size is so small and generated as an interactive map file since its format supports hyperlink.
