项目摘要

This research develops a digital archive of historical topographic maps in center of Tokyo after the Meiji mid term. The archive consists of historical topographic map images as raster data and digital terrain model as vector data, which is made by extracted elevation points, contour lines, and water lines. The archive makes it easy to quantitative analysis in wide area through various times.Through validation of accuracy of digital elevation model (DEM), DEM of The Tokyo 1:5000 scale Survey Map in 1888 is used to analyze topographic changes. The topographic change is extracted by comparison between DEM in 1888 and current 5m grid DEM published by Geographic Survey Institute. The analysis focuses on 836 places making use of the sampling process of the topographic changes, and classifies the changes according to era, form of the change, and land use change. As a result, in Tokyo topographic change has the following characteristics. First, the most frequent era of the topographic change is between 1884 and 1909, which is followed by between 1925 and 1930, and between 1956 and 1983. Second, development of building lots has the most influence on the topographic change. The development of building lots are mainly conducted by individual private development. Finally, reclamation of water area is mainly done very not only the Tokyo Bay area but also inland section. In addition, especially earth fills/cuts of slope area are seen to increase the available area for development of building lots in inland area.This study confirms the significance of the digital archive in historical study, and realize Tokyo again from the perspective of topographic changes.

这项研究在明治中期后，在东京中心开发了历史地形图的数字档案。该档案由历史地形图像作为栅格数据和数字地形模型作为矢量数据组成，由提取的高程点，轮廓线和水线制成。该档案使得通过各个时期可以轻松地在广泛区域进行定量分析。通过数字高程模型（DEM），东京DEM的精确性验证1888年的Tokyo 1：5000比例调查图用于分析地形变化。地形变化是通过1888年DEM与地理调查学院发表的当前5M GRID DEM的比较提取的。该分析的重点是利用地形更改的采样过程的836个地方，并根据ERA，变化的形式和土地使用变化对变化进行了分类。结果，东京地形变化具有以下特征。首先，地形变化的最常见时代是在1884年至1909年之间，其次是1925年至1930年，以及1956年至1983年之间。其次，建筑物的发展对地形变化的影响最大。建筑物的开发主要由个人私人发展进行。最后，对水地区的开垦不仅是东京湾地区，而且还进行了内陆区。此外，尤其是，尤其是，斜坡区域的地球填充/切口可以增加内陆区域建筑物批次开发的可用区域。这项研究证实了数字档案中历史研究中的重要性，并从地形变化的角度再次实现了东京。
