This data is based on the Natural Environment Conservation Basic Survey conducted by the Ministry of the Environment's Biodiversity Center. The spatial scale of this data set is in 1/25,000. Original data was prepared as a series of Shapefile and publially avaiable for your download (http://gis.biodic.go.jp/webgis/sc-025.html?kind=vg67). We downloaded and merged all shapefile while fixing various schema anomality. We also translated categorical descriptions into English using ChatGPT4o.
This is the most detailed vegetation map covering all of Japan. The Ministry of the Environment has been conducting the Natural Environment Conservation Basic Survey. The vegetation survey is a part of this extensive nationwide natural environment survey (http://gis.biodic.go.jp/webgis/sc-043.html).
The original data was prepared as shapefile and was divided into Japanese standard mesh areas. We downloaded all data files and merged into one GeoParquet file. During this merging process, we fixed a data schema anomaly. We also merged adjacent polygons from different mesh areas based on their attribute values.
All descriptive attribute values were in Japanese. So we extracted all unique attribute values and translated into English. We used ChatGPT4o for this translation. We cannot guarantee the translation accuracy, so please use these English descriptions at your own risk.
