Present project was planned and promoted with the two objectives. One is to issue gravity database constructed in Southwest Japan and to spread its gravimetric results. The other is to start gravity database construction to cover whole Japanese islands and to make all the original gravity data possible for public use.Main frame of our gravity database in Southwest Japan was well founded by developing the achievements of former four projects (the same category of Grant-in-Aid for Scientific Research : No.01540331 in 1989-1991, No.04640400. in 1992-1994, No.07640552 in 1995-1997 and No.11440130 in 1999-2000). By compiling all the data thus collected, we completed the gravity database in Southwest Japan which was published as a special roport of the Bulletin of the Nagoya University Museum in 2001 (Gravity Research Group in Southwest Japan, 2001; Representatives: R.Shichi and A.Yamamoto). Besides this, the gravity database called "Gravity (CD-ROM) of Japan" had been published in 2000 from … More the Geological Survey of Japan (present: National Institute of Advanced Industrial Science and Technology). By merging these two databases, we compiled a new gravity database to cover whole Japanese islands (JGDB). As concerned to the data coverage of this database JGDB, there still remains some parts of blank area in Northeast Japan. However, Southwest Japan is almost completely coverd with evenly distributed dense gravity data with very high precision of less than 1 mgal.By utilizing this desirable condition in Southwest Japan, we planned to publish a gravity atlas under a name "Gravity Atlas of Japanese Islands --Southwest Japan and Central Japan--". This is nothing but the concrete plan for the first objective of present project, and we have already finished preparation of the manusclipts.As for the second objective, we started working to collect and edit the existing data still remained unpublished. At this moment, we collected several tens of thousands gravity data mainly, distributed in Hokkaido and Kanto districts. They are now under edition. Less

本项目是围绕这两个目标来规划和推进的。一是发布在日本西南地区建立的重力数据库，推广其重力成果。二是开展重力数据库建设，覆盖整个日本列岛，使所有原始重力数据都能为公众所用，我们的西南日本重力数据库的主体框架是在前四个项目（1989-1991年同类型科研资助项目：No.01540331，No.04640400）成果的基础上建立起来的。1992-1994年、1995-1997年第07640552号、1999-2000年第11440130号）。通过汇总收集到的所有数据，我们完成了日本西南部的重力数据库，该数据库于2001年作为名古屋大学博物馆公报的特别报告发表（日本西南部重力研究小组，2001年;代表：R.Shichi和A.Yamamoto）。此外，2000年出版了名为“日本重力（光盘）”的重力数据库， ...更多信息 日本地质调查局（现：国家先进工业科学技术研究所）。通过合并这两个数据库，我们编制了一个新的重力数据库，以涵盖整个日本岛屿（JGDB）。关于该数据库JGDB的数据覆盖范围，在日本东北部仍有部分空白区域。然而，日本西南部地区几乎完全被均匀分布的、精度小于1 mgal的高密度重力数据所覆盖，利用这一有利条件，我们计划出版名为“日本诸岛--西南日本和中部--重力地图集"的重力地图集。这是本项目第一个目标的具体计划，我们已经完成了手册的准备工作。至于第二个目标，我们开始收集和编辑现有的数据仍然没有公布。目前，我们收集的重力数据主要有数万个，分布在北海道和关东地区。它们正在编辑中.少
