Background and purpose

In May 2016, I found the tool FGDV of the government of Japan can't handle coordinates in `` tags in `` as individual ring. Coordinates in `` and ``` tags are merged to a ring. It converts JPGIS GML to broken shape files. PSEA had a same problem. I needed a tool to convert JPGIS GML to right GeoJSON for my project.
