본 연구는 지도제작시 지도의 특성을 쉽게 인식하고, 자동화율을 향상시키기 위한 지형도 도식을 고안하였다. 지도 도식은 단순 명료하며, 기존의 지형도와 최대한 유사한 형태의 지도가 출력될 수 있도록 하는 원칙을 가지고 1/5,000 수치지도 Ver 2.0을 이용하여 수행하였다. 이를 위해 지도제작에 필요한 정보를 수치지도 Ver 2.0에서 획득하고, 기존 지형도 도식규정에서 표현하는 정보와 비교 분석하여 실무자들과 많은 협의과정을 거친 후, 지도 제작 자동화에 유리하면서 지도의 미적품질을 유지할 수 있는 도식을 고안하였다. 또한 지도제작 자동화 시스템에 의한 1/5,000수치지도 Ver 2.0의 시범제작을 통하여 새로운 도식을 적용한 결과 약 7%의 자동화율 보였으며, 이러한 결과로서 지도제작자동화율이 향상되었음을 알 수 있고, 사용자들이 지도의 특성을 쉽게 인식할 수 있도록 하였으며, 최신의 정보를 보다 손쉽게 얻을 수 있도록 하였다.

With the high demand for Geographic Information System and the diversification of Spatial Information, it has been required a rapid and accurate input system, updating system and an efficient field survey system to organize database for thematic mapping. Following the purpose, several indispensable modules have to be Invented to build a GPS Lap-top Computer System using low cost GPS receivers. These modules include such as an interface module between GPS receivers and lap-top computers, a data processing module for standalone GPS or Real-time Differential GPS, a module to input or amend digital map and to transfer three-dimensional coordinates in real-time, and finially a module to enter attribute value and feature code based on standard specification of digital maps for controlling position and attribute data. In this paper, it Is presented the efficiency of method to acquire and to input or to amend spatial information using a GPS Lap-top Computer System.

소음지도는 공간의 소음값을 3차원적으로 분석하여 GIS 데이터에 소음분석결과값을 RGB 값으로 표현한 것이다. 현재의 GIS는 2차원 데이터이므로 3차원 소음분석결과값을 표현하고 사용자들에게 제공하는 것에 효과적이지 못하다. 따라서 본 연구에서는 소음분석결과값을 보다 효과적으로 사용자들에게 제공하기 위하여 3차원 소음지도를 제작하고자 한다. 3차원 소음지도는 도시공간모델의 지형과 건물을 각각 소음분석결과값을 이용하여 texturing하여 가시화한 후 통합하여 완성한다. 지형의 경우, 지형의 기하학적 가시화완 지형의 texturing의 두 단계를 거쳐 완성하고 건물의 경우, 건물의 기하학적 3차원 가시화와 건물의 texturing의 두 단계를 거쳐 생성한다. 건물과 지형의 texturing의 단계에서 texture file은 소음분석결과값을 RGB코드로 변환하여 jpg파일로 생성한다. 생성된 3차원 소음지도는 영등포구 전체 영역을 대상지로 하였고 web기반의 VRML파일이다. 가시화의 효율성을 고려하여 영등포구 영역을 $200m{\times}200m$로 구역을 설정 607개의 구역으로 나누어 가시화하였다. 도시공간 모델을 이용하여 3차원 소음지도를 제작함으로써 도시공간모델을 이용하는 응용분야에서 3차원 공간분석의 가시화를 위한 방법을 제시할 수 있었다. 이를 통하여 공간 문제들의 결과를 사용자들에게 보다 효율적으로 제공할 수 있을 것이다.

정보화 기술의 발전과 더불어 GIS의 대중화에 따라, 다양한 형태와 주제로 공간 정보를 제공하는 수치지도의 수요가 증가하고 있다. 기존의 수치지도 데이터는 도엽 단위로 관리하기 때문에 관리 및 갱신을 효율적으로 지원하기 어렵다. 이 논문에서는 이러한 문제를 해결하기 위해 객체의 연속적인 표현, 객체 단위의 갱신 및 이력관리가 가능한 UFID기반의 수치지도 데이터 모델을 제안하였다. 제안한 모델은 각 지형지물에 새로운 UFID를 부여하여 연속적인 지형지물 표현과 갱신으로 인한 지형지물별 이력 관리가 가능하도록 하였다. 마지막으로 제안된 모델의 효율성을 검증하기 위하여 타당성을 분석하였다.

Wind power generation is the natural source energy without pollution, and the highest economic efficiency among renewable energies. Amid the recent development of small wind power generation, wind power generation facilities can be installed in the super high-rise buildings or complexes. It is necessary to conduct analyses on appropriate locations in a bid to promote efficient power generation in those locations. In this study, relative weight of the elements required for the wind power generation were estimated by using the Analytic Hierarchy Process in Busan City, and the characteristics of wind velocity and wind direction in Busan City were expressed. As a result, 'Dadae 1-dong, Cheolma-myeon, Noksan-dong' was selected as the candidate region inside Gangseo-gu, Gijang-gun, Saha-gu by using the geo-spatial information system.

Geographic information system extends several teamed circles so for and took in application step. Specially, GIS is applying much in civil engineering works field, and is trying to express terrain numerically and look for true value. It is very important that express terrain, can become important parameter to do three-dimensional analysis in later. We are using irregularity triangulation network mainly to express these terrain. In this study, calculated volume of topography by irregularity triangulation by developed formula.

There are several methods for building optimal eco-villages in a narrow territory. To derive a new optimal eco-village factors by combining environmental factors from ubiquitous sensor network and topography factors, this study attempted to investigate ecological spaces of specific human settlements, to compare those with the spatial analytical results on natural real settlements, and to draw a construction plan for an optimal ecological village. This study presented a new milestone for building eco-villages in the large or small village units of the entire country in the fact that we can find a living space to make natural healing possible by integrating ecological factors and wellbeing spatial configuration using more healthy natural space. Also, this study proposed a practical method to do so.

Generally, there are two methods which generates the base map of Geo-Spatial Information System(GSIS). one is the digitizing of existing map, and the other is the analytical plotting method editing data acquired by sensors using computers. But the analytical plotting method and method of the digitizing of existing map is technically complex and has the disadvantages in the costs and time. The subject region of study(the Kwangyang province), was photographed by aircraft, and photographing scale was 1/6,000. Then this area was divided into two specific regions, the residential area, and the agricultural area. In this study, we developed the algorithm that generated base map of database in GSIS from the aerial photo. This algorithm is as followed. First, the digital aerial photos were generated using these aerial photos. Second, these digital aerial photos were enhanced by implementing the histogram equalization. Third, the objects of the enhanced images were extracted by implementing thresholding and edged detection techiques of image segmentation. Finally, these images could be used to updated the base map of database in GSIS. The result obtained from this study showed that method used by this study were more efficient than existing method in costs and time.

The purpose of this paper is to use geo-spatial information system for effective operation and management of the underground facilities. The subject area is selected and collected all of the drawing in order to get the coordinate points(tic), which become the standard of the subject area and that can be gotten by way of practising control surveying from a existing triangulation station spatial information and attribute information are classificated from obtained data. Also, after giving the code in the attribute information to make it data-based, connecting spatial information with the attribute information to overlap layer each other, and compared the positional accuracy of the data. From the results of this study, conclusions are acquired as follows; 1) To construct the Database of the spatial and attribute data, which contain all kinds of drawings in underground structures, the reservation of registers and the details of changes and so on, results in easily referencing, compiling and analyzing the reserved data in system as their own purposes. 2) It is expected that we can effectively operate and manage the situation among the underground facilities so accurately that we may obviate the safety accidents or the damages of life and property.
