컴퓨터 지도의 발달과 GIS

김우관(Woo Gwan Kim),전영권(Young Gweon Jeon) 한국지역지리학회 1995 한국지역지리학회지 Vol.1 No.1

전자 기술의 발달은 지도 제작에 있어서 엄청난 발전을 초래하고 있다. 컴퓨터의 활용과 원격탐사에 의한 영상 정보는 지도학과 그 관련 분야에 일대 혁신을 가져다 주었다. 사진 측량에 의존하던 각종 주 제도의 제작은 인공위성에서 전송되는 자료에 의하여 그 기능이 대신하게 되었다. 이러한 변화는 기존의 지도 개념을 바꾸어 놓기에 충분하였다. 특히 컴퓨터 지도 분야는 대중성과 전문성을 동시에 가지고 있어서 다가오는 21세기에 그 수요가 폭증할 것으로 예상된다. 따라서 필자들은 지금까지 이 분야에 있어서 다양하게 개발되어온 결과들을 토대로 컴퓨터 지도에 관한 전망을 분석하였고 국내 컴퓨터 지도의 경우는 국내 GIS수준과 관련시켜 살펴보고 그 문제점과 개선책을 제시하여 보았다. The writers study on the development and the prospect of computer map based on the most recent computer mapping technical aspects. We also study domestic prospect of computer map in connection with the present condition of domestic GIS. The main results are as follows: ① Computer map has rapidly developed in spite of its short history. We expect that computer map will be improved more in the future owing to the development of computer hardware and software. Most mapping processes will be possible sooner or later owing to Artificial Intelligence(AI) and more improved scanner without human effort. ② Computer map can be used for various industrial fields and its development can give a great help for technical advance in correlated industries. ③ Computer map has really developed in the country since 1980, when GIS was introduced. Especially, government planned to digitalize all the basic topographical maps covering the whole country between 1996-1998. We think that there is an epoch-making change in the development history of computer map in the future. ④ The development of GIS is closely connected with one of computer map, but the recent technical levels of GIS is not perfect. So there is an urgent need for technical supplement to produce good computer maps. ⑤ The government had better construct GIS database in order to cut down expenses derived from overlapping input of data by individual users and there is a need for data standard.

This study is an investigation of the stream order in the Geumho river basins. The degree of land erosion is influenced by not only rainfalls but also land form and geologic conditions. In this study, the stream orders and stream lengths were investigated on the topographic maps (one meter is equivalent to 50,000 meters), in connection to their regional characters. The results are as follows: ⑴ The river basin may be divided into two major river basins according to its mainstream: the northern river basin and southern river basin, which again are subdivided into 13 subriver basins. ⑵ In these regions are distributed sedimentary rocks in about 66.06%, metamorphic rocks and plutonic rocks in about 12.42%, and volcanic rocks in about 21.52%. It was sedimentary rocks that accelerated the stream order. ⑶ In the Geumho river basins, an average of bifurcation ratio of stream orders is 4.07, and general speaking, the other bifurcation ratios are under 5. ⑷ In the Geumho river basin, the mainstream orders are the 6th river, and other subriver stream orders are 4th river according to Strahler method. the average length of river is about 20㎞.

Various techniques of remote sensing are applied to identify types of land cover on the Kimhae Delta Plain from its Landsat TM inage of November 21, 1984. The techniques used here are evaluated in terms of their effectiveness and limitation in land cover classification. And then examinations are made of distributional characteristics that individual land covers have over the area. The rssults of an effectiveness evaluation of remote sensing techniques in this study are as follows. 1. A Visual analysis of individual spectral bands shows that targets in the area are more easily distinguished in one band than in another one. 2. An analysis based on false color composite images shows that the combination of bands 4-3-2 is most effective for classifying large-scale land covers like manmade structure or vegetation ect. And band combinations of 5-4-3, 5-3-2, or 5-4-2 are complementarily needed for a detailed classificaton of vegetation or man-made structure. 3. Density slicing is found a useful technique to classify in detail water or soil of different quality. Especially, its application to the band 5 image shows a better result than that to any other bands. But density slicing is found inadequate for the area which has many terrestrial elements of subtle spectral difference mixed wildly. 4. A Supervised classification using the maximum likelihood method indicates that : 1) the band combination of 5-4-3 proves most effective in the land cover classification, which results in 16 different classes. 2) supervised classification provides more distinguishing accurate and interpretable results, and 3) agricultural produces such as green onion, radish/cabbage, and parsley are readily recognize, and for the first time it is found possible to distinguish between fresh and salt water, and between non-saline and saline soil. Distributional characteristics of individual land covers are as follows. 1. The Kimhae Delta Plain has an individual vegetable produce to concentrate over some specific areas. Green onion forms a large patch throughout Myungho-Do especially by covering its beach ridge of sandy soil in the coastal delta. Radish/cabbage centers around the natural levee along the Chukrim-Gang and the Pyongchon-Gang. And parsley forms a large patch in the Pombangri area. 2. Non-saline soil is located in paddy fields of the upper delta and its surrounding area, whereas saline soil is found in those of the lower delta. 3. The Pyongchon-Gang, Chukrim-Gang and Macdo-Gang are of fresh water, which have underwater facilities for protection againt salt water reflux in their mouths. In the year of 1984 when the Naktong River did not have such a facility, salt water appeared far inland along its main stream.

The result of this study are as follows; 1. A characteristic of the distribution 1) Considering as the distribution of a distance, apartment houses are in close order in a boundary of 3 Kilometers. 2) Considering as sectors, apartment houses consist of sector 1, 8, 5, and 6, these are the same regions as residental ones on the regional structure in the east, the west and south of Daegu city. 2. A characteristic of the spatial development 1) Period 1 has a dot-formed distribution. 2) In period 2, the private investment is began, and apartments are nearly approached towards C.B.D. that has centralization of the vacation and residence. On the other hand, they are developed as outward sprawling of residence. On the other hand, they are developed as outward sprawling of decentralization of vacation and residence. 3) Period 3 shows the tendency of spatial variation that develops agglomeration around a core of the apartments period 2. 3. A characteristic of the attribute 1) The price of the apartment houses are raised and their sizes are enlarged year by year. And the most of them are their own houses. 2) Many owners are mainly the productive age people that have vigorous activity in the economical and social field. Therefore, they are the persons with a higher education, and the most of them work as professional, technical, and clerical workers. They also consist of nuclear family system. 4. A characteristic of the condition of location 1) In view of topographical condition, apartment houses are in the low level lands, as for traffic condition, time distance(10 to 15 minutes) and spatial distance (2 to 4 Kilometers), they are locate in centralization of the vacation and residence. 2) As a whole, the urban facilities are good, but apartment houses have not a few weak points being far from markets and schools. Therefore, supplement of these things are keenly demanded.

Mt. Waryong situated on the western part of Daegu City is a monadnock (299.6m), which is formed erosional basin in the center of it. The main aim of this study is to clarify formation processes through analyzing the geological and geomorphological characteristics of study area. The summary of the characteristics are as follows; 1. The study area had been formed sedimentary rocks of Kyoungsang series at the Mesozoic era, and later, the intrusion of Bulguksa granite had occured. 2. In the center of the area, there is distributed Bulguksa granite, as it is the plutonic rocks which is weak to weathering that was formed erosional basin. 3. The surroundings of the area is formed ridge that is consist of metamorphic rocks(Hornfels) which is strong to weathering. And we can find rockfall zone of breccia here and there at the upper-slope. 4. As the result, the landform of mountain block is formed concave like 'U' letters open to northward. From the characteristics mentioneo above, we can classify formation processes in the Waryong mountain as follows; 1. Pre-forming period of the mountain. 2. The intrusion of granite and contact metamorphism period. 3. Differential erosion period.

This study has analysed on the drainage basin characteristics of the Yo^ung-san river according to the topographic map used by morphometry. Control factors of drainage basin are; First the most important control is rock types, second factors is the relative easiness of infiltration of precipitation into the ground surface and drownward to the water table, and third major factor is the presence or absence of vagetation cover. The stream orders, stream lengths, and drainage area have been investigated through the topographic map in 1 : 50,000. This table is shown up bifurcation ratio, average length, and drainage density by the method of the A.N, Strahler system ordering adapted over the whole basin. The result are as follows; 。The drainage basin may be divided into two major slopes accordong to its mainstream: North-west slopes and South-east slopes, which are again subdivided into 13 and 11 interbasins shown up figure 2. 。In the Yo^ung-san drainage basin, The main stream is found to be 7th order. The average of bifurcation ratio is 3.870, Southeast slope(under 4.00) is higher than North-west slope(over 4.00), and the reason is that stream order is influenced by geologic conditions. These ratio are lower than North Han-river basin (4.25) and Gum-ho river basin (4.07). The average drainage density of Yo^ung-san river basin is 1,126.23m. 。Correlation between order and number which is plotted on the semilog paper shows characteristics of natural streams in the old region.
