A feng-shui map(山圖) represents the most ideal natural landform on a map of feng-shui space model, highlighting propitious spots and grave sites in terms of feng-shui. This study made an analysis into feng-shui maps featured in the Chinese feng-shui manual Jiriinjasuji published in the Ming dynasty of China and did research on the following points regarding the traits of landform expressions: viewpoints of feng-shui maps, perspective points, center-oriented maps, double map scales, mountain theories, detailed expressions of propitious spots, etc. The major characteristics of landform expressions in the Chinese feng-shui manual Jiriinjasuji are as follows: the viewpoint technique was aerial one; the maps were center-oriented, that is to say, the center of grave sites or propitious spot was depicted in detail; and often the important terrains around grave sites were exaggerated or delete compared with real landforms. In addition, other vital landforms not observed from grave sites were depicted with viewpoints moved and were represented in greater details' The part of mountain theories had the following points as their main subject matter: geographical locations, overall orientations of mountain ranges, topographical traits, grave seat directions, surrounding terrains and extent of fortune-bringing. The directions of the maps were relative and there was no definite concept of scales. But, there are many cases where the maps made use of the double scale technique when expressing the terrains that have propitious space, logistical cities or directional importance. Furthermore, they often utilized multiple scale in expressing near views, mid-range views and distant views.

When literatures and cultures encounter their counterparts in terms of the big data or statistics of a new reconfiguration in the cognitive map, the tangential points of the borderland will be reduced to what Mitchell calls "a mere abstraction on a map," which nevertheless will provide a vast interstitial zone of "intersections, competition, and exclusions." This zone will be the dynamic vortex for the aesthetics, politics, and ethics of cultural translation. The translated discourse will engage in carrying across the disturbing region of untranslatability and demonstrate how the literary texts of world literature reveal enriching but threatening human experience. This dynamic border of vortex will construct the translational space of world literature, transcending the fragmentary untranslatable nature of the hybrid convergence of the ethnic, racial, cultural and national intermixtures and constructing what Pascal Casanova terms "The World Republic of Letters." In this paper, I will demonstrate how the very concept of scale is related to literary space as well as how distance creates a poetics of literary landscapes which looks ahead of world literature. Also, I will attempt to find the possibility to relate the "micro-scale" with the "macro-scale," and to construct the scale politics of representation. "Glocalization" is a convenient theoretical tool for the double movement of the up-scale and down-scale.

A feng-shui map is a kind of map that features such propitious positions as fortune-bringing spots or ideal grave sites. The map is a representation of the most ideal natural terrains in terms of feng-shui perspectives. This study did research on two feng-shui maps registered on some genealogical tables in order to see how the map was drawn up. In addition, the detailed characteristics of landform expressions like the frame of the map, viewpoints, center-oriented mapping, water flow, mountain theories were delved into. The results of the research are as follows: the feng-shui maps for this research used the techniques of double scale and aerial view, described terrains with grave sites in their centers, and enlarged important terrains compared with surroundings for exaggeration purposes. In addition, other vital landforms not observed from grave sites were depicted with viewpoints moved and were represented in fine details. The part of mountain theories had the following points as their main subject matter: geographical locations, overall orientations of mountain ranges, topographical traits, grave seat directions and surrounding terrains.

This article investigates the situation of the Plane Rectangular Coordinate derived from the Gauss Double Projection whereby the positioning of triangulation point in Korea has been represented on. Analyzing and assessing it have been performed by means of new computational method such as computer programing. On the basis of the results brought about, it is found that a new Plane Rectangular Coordinate as well as map projection and scale factor of geodetic length may be adapted to improve the distortion along the geodetic line on a certain zone of map projection in order to enhance the accuracy and the utility of the practical surveying works. The proposals for this study are as follows; (1) projection: Gauss-Kruger's projection (2) Coordinate system: Plane Rectangular coordinate with 8 origin system (3) Scale factor of geodetic length in origin; $m_0=0.9999$

Forest canopy height can be used for estimate of above-ground forest biomass (AGB) by means of the allometric equation. The remote locations and harsh conditions of mangrove forests limit the number of field inventory data stations needed for large-scale modeling of carbon and biomass dynamics. Although active and passive spaceborne sensors have proven successful in mapping mangroves globally, the sensors generally have coarse spatial resolution and overlook small-scale features. Here we generate a 12 m spatial resolution mangrove canopy height map from TanDEM-X data acquired over the world largest intact mangrove forest located in the Sundarbans. With single-pol. TanDEM-X data from 2011 to 2013, the proposed technique makes use of the fact that the double-bounce scattering that occurs between the water and mangrove trees yields water surface level elevation over mangrove forest areas, thus allowing us to estimate forest height with the assumption of an underlying flat topography. Our observations have led to a large-scale mangrove canopy height map over the entire Sundarbans region at a 12 m spatial resolution. Our canopy height estimates were validated with ground measurements acquired in 2015, a correlation coefficient of 0.83 and a RMSE of 0.84 m. With globally available TanDEM-X data, the technique described here will potentially provide accurate global maps of mangrove canopy height at 12 m spatial resolution and provide crucial information for understanding biomass and carbon dynamics in the mangrove ecosystems.

This study tries to generalize the stream network by constructing rule-based modelling. A study on the map generalization tends to be concentrated on development of algorithms for modification of linear features and evaluations to the limited cartographic elements. Rule-based modelling can help to improve previous algorithms by application of generalization process with the results that analyzing mapping principles and spatial distribution patterns of geographical phenomena. Rule-based modelling can be applied to generalize various cartographic elements, and make an effective on multi-scaling mapping in the digital environments. In this research, nile-based modelling for stream network is composed of generalization rule, algorithm for centerline extraction and linear features. Before generalization, drainage pattern was analyzed by the connectivity with lake to minimize logical errors. As a result, 17 streams with centerline are extracted from 108 double-lined streams. Total length of stream networks is reduced as 17% in 1:25,000 scale, and as 29% in 1:50,000. Simoo algorithm, which is developed to generalize linear features, is compared to Douglas-Peucker(D-P) algorithm. D-P made linear features rough due to the increase of data point distance and widening of external angle. But in Simoo, linear features are smoothed with the decrease of scale.
