PC-based CMS Development
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 107~116
Choropleth map is a type of thematic maps in which areal units are shaded with a color or pattern that symbolizes some characteristic of the mapped unit. CMS was first developed to produce choropleth maps on ordinary microcomputer environments in 1988. Since then there have been significant technological developments and enhancements in user environments, which have affected the field of choropleth mapping systems posi¬tively. A new version of CMS was developed in accordance with these changes. CMS II requires an IBM PC, or compatible, with the minimum 640KB memory and VGA graphic board. It supports HP laser jet printers to output a high resolution map. The program can use Hangul letters for main menu, map title, and legend. And dBase file format (DEW) was implemented to exchange attribute files effectively.
A Study on Urban Land Use Analysis using Land Information Systems
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 117~134
The problems of urban land use are becoming worse by the increase of population and facilities. Land use planning is the major part of comprehensive city plan¬ning. Understanding and forecasting the present and future conditions of land use are the main process of land use planning. In order to comprehend the various phenomena which occured on the land, collecting accurate land information is the most important thing for the effective management of land use. Therefore, it is necessary for us to establish the
Land Use Classification in the Seoul Metropolitan Region - An Application of Remote Sensing -
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 135~145
The primary purpose of this study is, using Landsat remote sensing data and a image processing software, ERDAS, to generate real data and image photographs on physical land use of the Seoul metropolitan region. The remote sensing data used in this study are Landsat MSS data (August 28, 1979) and TM data (May 31, 1991) which cover the Seoul metropolitan region of Korea. The spatial resolutions of MSS data and TM data are 57m X 79m and 30m X 30m respectively. In addition, this study aims at contrasting urbanization phases of the Seoul metropolitan region in 1979 with those in 1991, by making image photographs and statistics on physical land use. Summing up the major results, built-up area ratio within the Seoul city had been expanded from 41.9% in 1979 to 64.5% in 1991 and that within the radius of 40km of Seoul city hall had been expanded from 10.5% In 1979 to 19.8% in 1991. The data and technique developed in this study could serve as a useful tool in making various kinds of spatial plannings, that is, urban and regional planning, selection of optimal new town location, evaluation of public facilities location alternatives, etc..
Transportation Network Data Generation from the Topological Geographic Database
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 147~163
This paper presents three methods of generating the transportation network data out of the topological geographic database in the hope that the conversion of the geographic database file containing the topology to the conventional node-link type trans¬portation network file may facilitate the integration between transportation planning mod¬els and GIS by alleviating the inherent problems of both computing environments. One way of the proposed conversion method is to use the conversion software that allows the bi-directional conversion between the UTPS (Urban Transportation Planning System) type transportation planning model and GIS. The other two methods of data structure conversion approach directly transform the GIS's user-level topology into the transportation network data topology, and have been introduced with codes programmed with FORTRAN and AML (Arc Macro Language) of ARC/INFO. If used successfully, any approach would not only improve the efficiency of transportation planning process and the associated decision-making activities in it, but enhance the productivity of trans¬portation planning agencies.
GIS Technology for Soil Loss Analysis
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 165~174
Soil loss was estimated by using universal soil loss equation(USLE) through GIS technique in Buyeu area. The expected soil loss is determined from six environmental factors: rainfall, erodibility of selected soil, length and steepness (gradient) of ground
Study on Application of Neural Network for Unsupervised Training of Remote Sensing Data
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 175~188
A competitive learning network was proposed as unsupervised training method of remote sensing data, Its performance and computational re¬quirements were compared with conventional clustering techniques such as Se¬quential and K - Means. An airborne remote sensing data set was used to study the performance of these classifiers. The proposed algorithm required a little more computational time than the conventional techniques. However, the perform¬ance of competitive learning network algorithm was found to be slightly more than those of Sequential and K - Means clustering techniques.
Map Segmentation Using Adaptive Smoothing Filter
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 189~196
Adaptive smoothing filter is a filter that averages out the intensities around the pixels of similar intensities while conserving the discontinuties. When human eyes rec-ognize a map, the brain can easily assign one color for each element such as road or building while computer distinguishes all the minute color differences even for one ele¬ment. We can approach to the solution by using the adaptive smoothing filter so that the
Automatic Geographical Entity Recognition and Modeling for Land Registered Map
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 197~205
In this paper, we present a vectorization algorithm for finding a vector image from a raster image of the land registered map which is used as the base map for various applications, and an automatic region creation algorithm for generating every re¬gion automatically from the vector image. We describe an ARM (automatic geographical entity recognition and modeling software) which carries out the recognition and process¬ing of geographical entities automatically using those algorithms
The Study on the Structure of Korean Digital Map
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 207~218
To activate the use of GIS, it is required to support a reliable digi-tal map. A digital map could be the base for other forms of maps as well as for direct applications, In this paper, the structure of such a basic map is pro¬posed. The structure is designed on the consideration of generality and classifica¬tion. The map data files are all character files and classification codes are pro¬posed.
"지도자료 입력 소프트웨어에 관한 연구"
Journal of Korea Spatial Information Society, volume 2, issue 2, 1994, Pages 219~224
The construction of digital map which is the basis of GIS becomes more important. The digital map is made up of image, numeric, and character data. The development of mapping system which makes the data inputted easily is important. In this paper interactive map¬ping system is introduced, which is currently developed. Also, map data structure is seriously discussed. The points of improvement on this system are considered.
