  • This study examined the method of making high-quality serial cadastral map with field surveying, the renewal and applications of serial cadastral map which is made for the application of notification of various topographical maps, and related legal and institutional contents. The results of the study are as follows. First, we suggested the way of modification that enables preexisting methods to connect with field surveying in order to improve utilizability of serial cadastral map that is not utilized properly. In addition, we came up with legal grounds from a current law, 'act on surveying watercourses survey and cadastre' for the modification. We also examined legal and institutional factors, the renewal and application of various notifications of topographical maps for efficient application, and the application of modified serial cadastral map for field surveying. Once the current cadastral map is modified based on the results of our study, it is possible that notification of topographical maps gets more accurate, and serial cadastral map can be used for field surveying. In addition, the modification can be utilized for a step-by-step strategy that reduces the existing cadastral map managed as 3 types into the cadastral map managed as 1 type.

  • This study aims to establish administrative boundaries by utilizing digitalized old topographical map. Various problems have arisen due to unclear administrative boundaries. For example, there are various problems such as conflict amongst residents to occupy a larger area, unnecessary waste of administrative power, and difficulty in collecting various data for administrative units (farm area, statistical data, spatial analysis, living ara analysis). Therefore, in this study, an experimental study was conducted to establish administrative boundaries by using an old topographical map containing information on villages before administrative reform in 1914. As a result, the boundaries of towns, towns and villages were largely consistent. In order to divide the administrative boundaries based on the legal district boundaries, the administrative boundaries were established by referring to the contents of village introduction and natural boundaries (roads, rivers, mountain ranges, etc.) provided in towns and villages. However, there was a limit in establishing a precise boundary as it was not possible to secure a high-quality digitalized old topographical map.

  • Because the current numerical value map and update system in use do not reflect rapidly enough the transformation of topography, their usage are gradually in decrease. Therefore, there is an increasing demand for reception update system of numerical value map which can guarantee the accuracy and up-to-dateness of data. While rapid detection of topographical transformation is essential for rapid updating, the existing research based on remote investigation or direct measurement was difficult to apply efficiently in terms of cost and accuracy. Thereupon, this research aims to present efficient methods of detecting topographical transformations for a frequent real time updating of numerical value map using the topographical transformation and related data inputted in real time into the administrative information system.

  • The Navigation Streets Map that directly supplies information for a driver plays an important role in Car Navigation System(CNS). Therefore, cause the compatibility, preference, visibility, and readability of the navigation streets map will be hold sway over driver's information acquisition, safety, and performance in CNS, it is important that designer's requirements should be analyuzed for ergonomic design of navigation streets map. Especially, there are differences between the topographical objects marking method and that of the general map in a navigation streets map. Because much information is marked in a narrow space, it is important that the text information should be done in navigation streets map. Also, because it is a important factor to mark the text format for the marking method of the topographical objects, the design requirements will be drawn out through the factor analysis for the text marking method. And when ergonomic designers are doing, this result will be basic research for developing driving simulator of CNS and it will be a ergonomic guideline of navigation streets map.

  • In this paper, we proposed a new algorithm for determination of many-to-many corresponding pairs between block-polygon sets from the national topographical map and the cadastral map in Korea Land Information System, caused by different abstraction and generalization rules of the two maps. Our proposed algorithm starts from an assumption that a block-polygon for a N:M pair should significantly overlap at least one block polygon of the counterpart group, and determines N:M pairs using an iterative updating and searching with this overlapping analysis. This iteration process is terminated when the N:M corresponding pairs satisfy our predefined 1:1 corresponding condition.

  • In order to plunder the Korean Peninsula in earnest, 'Modern Age Korea Topographical Map' of reduced 1:50,000 scale was manufactured within the period of 5 years from 1914 to 1918 through Japanese government-general of Joseson. This map includes all the data representing the life model of Korean Peninsula in the period of the End of Korean Empire, before the modern public construction works had started to seriously develop. This study analyzes the land use change after embedding the coordinates to the image of Modern Age Korea Topographical Map, which includes the scenery of 1910, and then overlaying it with the contemporary map in GIS environment. The results of presented research showed that before modern civil construction works started, the farmlands had lost their competitiveness because of difficult for development hilly areas and frequent floods, the river sites being abandoned and industrial structure change, and were developed into modern city area.

  • In this study, a wind hazard map over Korea peninsula based on geographical information is developed, which consists of the surface roughness model, the topographical effect model and the homogeneous wind model. The surface roughness model is assessed to evaluate the effect of the surface roughness on the wind field near ground. The topographical effect model is assessed to quantify the effect of the speed-up caused by topology, which is calculated by adopting the topographical effect factor in Korea building code (2005). The homogeneous wind map is created either by a frequency analysis method for meteorological data or a typhoon simulation. The results show that the wind hazard map can be applied to the determination of insurance premium as well as the assessment of loss and damage.
