ALOS DSM: Global 30m (JAXA/ALOS/AW3D30_V1_1)
Version 1.1
ALOS World 3D - 30m (AW3D30) is a global digital surface model (DSM) dataset with a horizontal resolution of approximately 30 meters (1 arcsec mesh). The dataset is based on the DSM dataset (5-meter mesh version) of the World 3D Topographic Data. More details are available in the dataset documentation.
| Name | Description | Gee Unit |
|---|---|---|
| AVE | Elevation value calculated by average resampling a 5-meter mesh model. | Meters |
| MED | Elevation value calculated by median resampling a 5-meter mesh model. | Meters |
| AVE_STK | Stacking number of the scene unit DSM used in producing DSM. The band is derived by resampling the stacking number for 5m resolution DSM to 30m resolution. | |
| MED_STK | Stacking number of the scene unit DSM used in producing DSM. The band is derived by resampling the stacking number for 5m resolution DSM to 30m resolution. | |
| AVE_MSK | 8-bit mask for the ave band. | |
| MED_MSK | 8-bit mask for the med band. |
