  • 최근 완도 관제구역 내에서는 자주 발생하고 있는 예부선 사고를 관제화면을 통해 분석하여 보았다. 무엇보다도 예부선을 주요 항행위험 유발선박으로 인식하여 관제 우선 선박으로 관리하는 것이 중요하다는 것을 알 수 있었다. 현장사진 위주로 실제적인 예부선의 조종특성과 항행상의 문제점을 알아보았다. 또한 개항질서법 상에 우선피항선으로 규정된 예부선의 법적지위를 고찰함으로써 관제 업무에 도움이 되고자 하였다.

  • 현지조사 및 측량은 GIS 데이터 구축에 있어서 가장 기본이 되는 작업으로 정확성과 효율성이 요구됨에도 불구하고 기존의 방법은 여러 단계로 분리되어 오류발생 빈도가 높고 또한 많은 시간과 비용이 소요되었다. 본 연구에서는 현지조사 및 측량에서의 정확도 향상은 물론이고 현장에서의 측량 편의성 증대에 목적을 두고 시스템을 개발하였다. 개발된 실시간 현지조사ㆍ측량시스템은 작업 현장에서 측량과 조사를 동시에 실시하며 조사항목을 직접 구조화할 수 있는 기능과 사진을 촬영하여 직접 시설물에 사진정보를 부착할 수 있는 기능이 있어 정확한 현지조사 및 사후관리가 가능하다.

  • Eeffectual use or management of coastal zone is very important problem inside of protection of marine resources as well as land use. Coastal Phenomena are very strong in its locality, each coast has its characteristic problem. Occasionaly we have to solve such problem by three dimension, but it is very difficult to solve it by traditional methods. If we use aerial stereo photographs, we can obtain high usefullness in coastal zone management. Also aerial photographs are very effectual to explain corelation of time to coastal dynamic phenomena and pattern which can not be explained by formula. Images obtained from remote sensors or radiometers bring up usefull informations to planer conected with coastal zone management, have additional value which can be treated and quantitatively analized so as to be read automaticaly and present speedy and low-priced techniques. So, I insist on that sooner or later total image procssor system for Remote Sensing and photo interpretation system must be established in our nation.

  • Lately, with the development of the fields of computer and photogrammetry, Digital Photogrammetric Systems are widely used for the generation of GIS basemap, the acquisition of topographic information and DEM, the formation of digital orthophoto, three-dimensional viewing and so on. According as the demand for the systems is rapidly increasing, we suggest keenly the necessity of domestic technical development, because all of these systems depend on foreign technology until now. In this study, by using digital photogrammetry method, with Visual C++ language, we have developed Digital Photogrammetric Systems for Windows which is able to get three-dimensional coordinates through interior orientation, exterior orientation, epipolar line, image matching from a pair of aerial photos taken with metric camera. This system consists of not only a module which can revise digital map that is being made at National Geographic Institute as a part of data construction project of National Geographic Information System, but also a module which can view three-dimensional image on the screen monitor by using anaglyph for three-dimensional analysis. The digital photogrammetry modules developed in this study are expected to be used as primary modules for the effective management of the urban as well as main modules in developing professional digital photogrammetric systems.

  • In this study, sample sites are chosen where digitalized cadastral maps are available, and boundaries of forestry, farming lands, and residence are clearly distinguishable. Digital orthophotos, produced from aerial photographs, are overlaid with digitalized cadastral maps to grope for applications of digital orthophoto in cadastre. The conclusions and applicable fields of this study are as follows. The first. digital orthophoto is applicable to solve problems such as discordance and duplication of boundary produced in the process of digitizing cadastral maps. The second, using digital orthophoto, it is possible to extract regions where a trouble of ownership would exist and so the necessity of cadastral resurveying can be brought. The third, by overlaying digital orthophoto and cadastral map, it can be used effectively for the present situation maintenance of buildings. The fourth, because it is possible to examine current land use of each lot, digital orthophoto may contribute to decide the validity of land category on cadastral map.
