File name：GeoTerrain_Zone_GeoTIFF_20250501.tif
Projection：JGD2000（EPSG:4612）
Resolution：Quarter Grid Square (approximately 250 m)

Pixcel values of the GeoTIFF are Zone numbers.
Zone numbers and explanations are as follows.

0: Slopes where the majority of the area is gently sloping such as alluvial plains, terraces, and alluvial fans, and where the sediment disaster special hazard zones as of fiscal year 2023 is not included in the grid
1: Slopes that include the sediment disaster special hazard zones as of fiscal year 2023, although the majority of the slopes are gentle as in Zone 0
2: Slopes where unconsolidated mountains or hilly mountains to hilly terraces, or relatively new-age tephra-origin soils are placed on mountains or hills
3: Hilly terraces and debris valleys, etc. formed by soft rocks
4: Hilly mountains formed by layered soft rocks
5: Mountains and hilly mountains formed by soft rocks of massive bedrock (less influenced by tephra) or mountains formed by layered soft rocks
6: Mountains, hilly mountains, hilly terraces, debris valleys, etc. formed by hard and medium-hard rocks


Please note that the areas of the sediment disaster special hazard zones used in Zone 0 and 1 are not identical to the current areas.
