Forest, water system, Rest Area/Service Area, and national/quasi-national park polygon data

Various polygon data (forests, water bodies, Rest Area/Service Area (service areas, parking areas),
national quasi-national parks) to enrich the representation of the background map.
The polygon data of Rest Area/Service Area and National/Quasi-National Park is linked to the POI (spot) data, and the water system data is linked to the name table.
Names and attributes can be determined.
By enhancing the visual representation of the natural environment, these data can be used for various purposes such as tourist information, disaster prevention planning, and environmental analysis.
