The aim of this paper is to propose the grasping method of the pattern and level of the agglomeration of land use using remote-sensing data. Using "CN Index" developed by Kobayashi et al. we propose a new Index, "Distance Index", which can clarify the level of the agglomeration of land use of a large regional area. DI Index is a potential value calculated based on distribution of CN index. In the paper firstly we abstracted the pattern of land use by classification from their land-surface situation using remote-sensing data of West Aichi. Secondly we measured the DI Index. Then we checked the land use pattern of West Aichi using DI Index and considered the feature. As a result by using DI Index the level of the agglomeration of land use could be classified comparatively clearly and especially the shape of the edge of agglomeration could be figured.
