Caution
- When the coordinate system is an arbitrary coordinate system, the coordinates used to export GeoJSON are exported as is without converting them to longitude and latitude by swapping the X and Y coordinates recorded in the XML file.
- The name of 筆 is a combination of 大字 name, 丁目 name, and 地番. This is because different 地番区域 may be stored in a single file in the map XML data file, and uniqueness cannot be ensured with 地番 alone.
- The line area displayed in the map image view is different from 地積 recorded in the registration record. In most cases, the numbers do not match. It is calculated using the coordinate values recorded in the map XML data file.
