본 연구는 일본 최초로 일본 전국을 실측하여 「大日本沿海與地全圖」를 제작한 이노우 타다타카라는 인물의 일생과 업적에 대하여 고찰한 것이다. 일본의 대표적인 지도학자인 이노우가 50세에 이르러 학문에 입문하기 전까지의 삶과 시대적 배경을 살펴보고, 그가 일본 전국을 측량하여 지도를 제작하기까지의 전 과정을 고찰하였다. 이노우는 천문현상을 보다 정확히 예측하기 위하여 위도 1도의 실제 거리 등을 정확히 파악하기 위하여 측량을 시작하였다. 그러나 당시 일련의 역사적 ․사회적 배경으로 인해 지도의 중요성과 필요성이 인식되었으며, 결국 에도막부의 공식사업으로 인정되어 「大日本沿海與地全圖」가 완성될 수 있었다. This study considers the life and achievements of Tadataka Ino, who is the representative Japanese geographer and made the first map of Japan by land surveying; Dainihon enkai yochi zenzu. We mainly investigate his life before he began to study regularly in his fifties, the historic and social background of Japan at that time, and also the whole process of making the map by the land surveying of the whole Japan. At first, Tadataka Ino began the land surveying with his individual effort in order to measure the correct distance of latitude 1 degree. But finally, this map was completed as the official work of the Tokugawa Shogunate, because the importance and necessity of the map had come to be more widely acknowledged in the historic and social background of Japan at that time.

南榮佑(Nam Young-Woo),北田晃司,孫承浩,成銀榮 대한국토·도시계획학회 2000 國土計劃 Vol.35 No.2
The main purpose of this study is to compare the raw data matrix with adjacency matrix based on OD data matrix about personal trips by zones(Gu units) in order to grasp the regional linkage system and the nodal regional structure of Seoul. The direct connection method and graph theory are mainly used to make a comparative analysis. The results of analysis are as follows : (1) After comparing the original OD matrix R and adjacency matrix B, concerning indispensable sides and topological network, we can find that there are some differences from the problem of 'direct and indirect linkages', 'attenuation', 'unequal linkages'. The difference in these sides are observed in all cases of the trips in business, shopping and total, except for commuting trips. (2) It is necessary to transform the raw data of each column X<SUB>IJ</SUB> from original OD data matrix into the relative value y<SUB>ij</SUB> in calculating the ratio of each to the column total. The problem of 'redundancy' or 'attenuation' due to matrix power series can be easily identified by the analysis of the first adjacency matrix Y. (3) The adjacency matrix B is considered to be very useful in analyzing OD data, because it can consider the indirect connection between origins and destinations. However, the third stage of adjacency matrix B<SUP>*</SUP> can be enough to be calculated in case of Seoul. because there is no 0 value column in adjacency matrix B<SUP>*</SUP> by this stage.
