Currently, the process of constructing a high-definition road map has a high proportion of manual labor, so there are limitations in construction time and cost. Research to automate map production with high-definition road maps using artificial intelligence is being actively conducted, but since the construction of training data for the map construction is also done manually, there is a need to automatically build training data. Therefore, in this study, after converting to images using point clouds acquired by a mobile mapping system, the road marking areas were extracted through image reclassification and overlap analysis using thresholds. Then, a methodology was proposed to automatically construct training data for deep learning data for the high-definition road map through the classification of the polygon types in the extracted regions. As a result of training 2,764 lane data constructed through the proposed methodology on a deep learning-based PointNet model, the training accuracy was 99.977%, and as a result of predicting the lanes of three color types using the trained model, the accuracy was 99.566%. Therefore, it was found that the methodology proposed in this study can efficiently produce training data for high-definition road maps, and it is believed that the map production process of road markings can also be automated.

Digital map is very important digital geographic information which is the base for various fields such as building and using the geographic information system (GIS), planing the regional development, and etc. Therefore, it needs high accuracy. Then we offer the advanced technique which minimizes errors on digital maps, using the automated inspection through the whole figures. In addition this new technique raises the economical efficiency as well as accuracy applying the automated error detection method which can recognize, search and classify errors automatically.

Digital road map - which plays an essential role in giving accurate location of the vehicle, optimum route guidance, destination searching, and topographic feature query functions - is the most fundamental element of the vehicle navigation system. Unfortunately, there is not a nation-wide digital map in Korea such as U.S. TIGER fie, that is easily applied to digital road database production. Therefore, producing new digital road map is inevitable in Korea For establishing digital road map for vehicle navigation, this paper puts forth the necessary condition to stabilize the digital road map qualify, and to keep up the compatibility and the economical use. As a result, the standards of coordinate and map accuracy arc presented, and the Items and the structures of database arc decided.

3D 입체영상을 제작하기 위해서는 2D 영상제작에 비해 오랜 제작 기간과 많은 비용이 발생한다. 비용 절감을 위해 기존의 2D 영상을 3D 입체영상으로 변환하는 연구가 진행되고 있다. 2D 영상을 3D 입체영상으로 변환하는 방식은 자동변환방법과 수동변환방법으로 구분할 수 있으며, 고품질의 2D-3D 변환 영상을 획득하기 위해서는 깊이정보 지도(Depth map chart)를 활용한 수동변환 방법을 많이 사용되고 있다. 하지만 2D-3D 수동변환에 사용되는 깊이정보 지도의 정량적 분석 데이터가 부족하여 사용자가 변환한 이미지에 대한 정확한 기준 깊이값 설정이 어려운 단점이 있다. 본 논문에서는 깊이정보 지도의 깊이값 정보에 대한 정량적 분석 데이터를 바탕으로 한 2D-3D 수동변환 변화범위를 제시함으로써 적정한 영상 변화를 유도할 수 있도록 한다.

After oil shock, the importance of renewable energy has emerged and it came to the fore again as Korean government declared the policy on low-carbon green growth. Among various renewable energies, it is generally accepted that wind power is the most practical alternative. In this paper we showed the process of producing wind speed map from Gangwon Regional Meteorological Administration's 2008 data. We mapped monthly average and maximum wind speed and compared several interpolation methods applied to the weather data. This wind speed map, which reflects Gangwon's topographical and climatic regional characteristics, is expected to be a good tool for wind farm location analysis.

Car Navigation System with Global Positioning System (GPS) can display position direction and the shortest cut of one's destination. The position datum for GPS in World Geodetic System 1984 (WGS-84) coordinates system need to transform Bessel coordinates system and process Map projection. Since 1987, GPS has used the WGS-84. WGS-84 is a geocentric equipotential ellipsoid of revolution which is defined four parameters. In this study, by comparing the digitized topographical map with the digital map of GPS datum we can consider the technique of WGS84 digital map.

The import of cartography is spoke for surveying technique level of the country. Also, it is the implied expression means about international operations amount in the world of people in the country. Nowadays, various digital maps on a reduced scale were drawn in Korea including the topographic series of a nation. Though these digital maps are drawn and revised by using aerial photogrammetry or satellite image, there are some problems that it is difficult to revise or renew the topography and natural feature immediately which changes frequently. As the countermeasures of these problems we use 3D Laser Scanning accumbency method, which provides user with convenience and accumbency accuracy which is required to revise and renew digital maps.

본 연구는 센서스와 GIS가 어떻게 연계활용 될 수 있는지, 센서스 자료의 원할한 활용을 위한 전용의 수치지도가 왜 필요하며 그 제작은 어떠하여야 할지, 인구주택센서스 자료들의 발표기본단위가 될 센서스트랙과 블락 그룹이 왜 필요하며 어떻게 결정되어야 할 지에 관한 연구를 수행하였다. 본 연구의 결론에 의하면: 첫째, 센서스와 GIS가 결합됨으로 인하여 센서스의 방법이며 절차가 좀더 명확히 효율적으로 진행될 수 있고, 각종 분석과 표현이 다양해지고 용이해질 수 있으므로 이에 대한 고려와 연구가 요구되며, 둘째, 한국에서 제작되고 있는 각종의 수치지도들은 방대한 정보들을 포함하고 있어 제작기간이 길고 갱신상의 어려움이 존재하므로 센서스만을 위한 간결한 수치지도를 간략히 개편하여 활용하여도 좋다고 보며, 셋째, 센서스자료의 기본발표단위를 현재의 읍, 면, 동 보다 좀더 세분화된 센서스트랙과 블락그룹 등으로 지정하여야 자료의 유용도가 높아질 것으로 본다. 이들 경계선응 현재 인구주택총조사에 쓰이고 있는 조사구의 경계와 근린주구 이론과 아울러 여러 가지 물리적, 사회적, 경제적, 행정적 요소들을 감안하여 결정하는데, 한 개의 센서스트랙에 인구를 4,000명 정도로 하고 블락그룹은 1,500명 정도로 하되, 한 개의 센서스트랙에 1-9개의 블락그룹이 탄력성 있게 포함되도록 하면 좋을 것으로 본다.

Satellite remote sensing images have much more information compared to a paper map. But these images are generally handled as particular image format gained from optical sensor, and must be processed and analyzed by computer with high priced digital image processing system. For the extraction of digital elevation model(DEM) from satellite image, we used the overlay image by SPOT-3 of Chuncheon area at the Kangwon province. According to the image condition, the precious geometric correction, the bundle adjustment for ortho-image generation and the stereo image mapping by several technical approaches were processed. So that we developed the methods of automatic DEM extraction and efficient stereo image map generation which can improve the digital image processing steps. Also, we applied the multiple direction birdeye view image for modeling and analysis using the remotely sensed overlay images with high resolution.
