| Outline of Final Research Achievements |
We developed hi-resolution and hi-accuracy Rapid Survey Maps raster data and a land use data base as a 100 m grid point data. Error of point based land use data is less than 1% compared with vector based land use data. We also developed landscape database which include a sketch of landscape in 130 years ago and hi-definition 360 degree panorama photo.Then, we analysed land use/cover change from the 1880's to 2010's. A model-based clustering method was applied to the land use/cover change data were summarized based on a 1 km by 1 km grid. The land use/cover change was classified into 29 categories, and we applied multi-dimensional scaling analysis to categorize data. Based on MDS analysis, the categories were divided into 6 groups, and each land use/cover change category had a strong relation with distance and direction from Tokyo and topographical features.
Develped land use/cover database have been converted to GeoJSON and uploaded to GitHub as open data (CC BY 4.0 International).
