The development of electronic technology brings the advent of elctronic totalstation which measures, stores and records automatically angles, distances and 3d coordinates. Electronic totalstation is the surveying equipment and system 2000 is the supporting program that enables totalstation to get 3d terrain information, construction of the database and automatic drafting of the cartographic map. In this study, we aims at studying the system which can produce automatically the digital cartographic map by using totalstation and system 2000. For this study, cartographic maps of a region are produced by totalstation and system 2000, and then builded digital cartographic map on the autocad 2000 environment and also we analysed two digital cartographic maps. As a results of this study, it is found that digital cartographic map by totalstation and system 2000 are much more accurate and efficient than cartographic map by electronic plan table surveying, as well as this digital map may contribute to build the GSIS coverage map using Arc/Info or Arcview GIS program.

This thesis is concerned with verification of the accuracy of the geographical procedure using results if GPS satellite survey. Errors in longitude and latitude deduced by the procedure have been examined using GPS based survey results in Korea and Japan. A total of 17 sets of data(10 obtained in this study from region near the city of Kwangju and 7 from japanese National Geographical instutite) were analyzed. It turns out that GPS survery is fast and accurate enough to utilize in filed survey. It is however necessary to define local geographical transformation coefficient and construct fine domestic geodetic networks in priori.

고대유물은 여러 가지 유형이 있으며 동산문화재중 재질로 보아 금속, 목재, 석재, 종이, 섬유, 흙, 등 다양한 소재로 구성되어있다. 이러한 고대유물의 올바르고 효과적인 보존·관리를 위하여 과학지식과 기술을 응용하여 유물의 제작기법과 그 역사 등을 규명함으로써 원형을 보존함과 동시에 문화재의 보존을 위한 방법과 이론을 체계적으로 밝히는 연구분야가 문화재보존과학(Cultural Properties Conservation Science) 이다. 이와 더불어 본 의뢰 유물의 성격상 역사적, 고고학적으로 매우 중요하게 평가되는 유물이다. 특히, 철제갑옷과 투구는 그다지 흔하지 않은 유물로써 우리나라 무구류 연구에 좋은 고고자료로 평가된다. 따라서 X-선(X-ray Radiography, Model : SOFTEX PRO TEST-150, Japan)을 이용한 고대 제작기술에 대한 분석을 실시하였다. 그 결과 고대 투구의 제조공정은 덩이쇠(철정)를 열처리하여 반복단조, 침탄, 담금질 등의 제련과정을 거친 철판으로 단타(hammering)하여 만든 단조품 이었으며 또한, 부식산화물로 감춰진 고대금속공예기술에서 각 장식부분의 접합기술은 釘孔을 뚫어 연접하는 방식을 사용하고 환두대도의 병부는 철환위에 은박판을 말아서 제작하였다. 특히 본 유물에서 X-선의 주목할 효과는 결실된 부분에 조잡한 재료로 눈가림의 복원상태를 확인 할 수 있었다. 문화재의 원형보존을 위한 과학적 보존처리의 각 단계마다 처리 공정과 방법론을 기술하여 이후 본 유물의 문제가 재발생 할 시에 보존방안을 강구 할 수 있도록 함과 항구적인 보존·관리와 본 유물이 지닌 속성에 대하여 학계에 보고 하고자 한다.

GPS positioning provides the geocentric position for individual receivers or relative positions between co-observing receivers. This system was developed for the purpose of military applications but more advanced GPS technology is applied in Navigation. Surveying, Traffic control, protecting Envirnment, etc. The Navstar GPS employs orbiting satellites. From Navstar satellites broadcast precise, reliable, and continuous navigation signals to a worldwide class of users. The achievable accyuracy adpends on many factors, as will be detailed throughout refernce book of this paper. Geocentric and relative positional accuracy and analysing precision using GPS of real survey data observation in the field is treated in this thesis.

Since defined as urban plan, Korean urban facilities are being placed on the status of non-execution caused by a number of factors. Particularly 73 cities occupy more than 70% of non-execution facilities, and followed the infringement of property right - generally accepted as a non-solved critical problem - whose possess above land owner. Hereby I suggest to improve non-execution facilities to cure our whole urban facilities, thus searching the reality of non-execution facilities and try to solve the solution thereby. As a concern arrangements, I suggest the solution to reduce and solve the non-execution facilities under the gradual and positive countermeasure as following by ; First, Korean non-execution facilities are on the critical situation, caused by financial insuffiency, but most of this followed by the lots of matters. Second, after analyzing the execution and non-execution facilities, most of the limited facilities are being executed and non-execution facilities might be long-termed tendency. Third, on the searching of the tendency of fundamental and time delayed execution facilities as the base of population scale, it could be figure out the typification under the control of non-execution facilities, and hereby suggest the lists which of characters. According to the analyzing contents on above mentioned, our non-execution facilities come to the point of crisis and urgently need to prepare turning point followed by the various direction of our current society to overcome.

Recently, laser technology has advanced to a point where accurate short-and long-lange measurements are possible to even relatively non-reflective object. This accuracy is achievable with a laser that meets the Federral Food and Drug Administration (FDA) eye safty requirments and is classified as eye-safe to Class 1 limits. This is a stand-alone instrument that has computing, editing and storage capabilities. Fore more complex computations, such as for volum or acreage determination, it has a serial connector which provides an interface with hand-held field computers or PCs. The most common use for this instrument on enginnering projects has been for load and trail pre-constrution surveys. Its portability, quick and easy operation, and record storage capacity make it well suited for this application.
