Bands Table
| Name | Description | Units |
|---|---|---|
| wth | River channel width at the channel centerlines. River channel width is calculated by the method described in [Yamazaki et al. 2012, WRR], with some improvements/changes on the algorithm. This band was upscaled to 18 arc seconds from the original 3 arc seconds for better visualization at global scale. | |
| upa | Upstream drainage area (flow accumulation area). This band was upscaled to 18 arc seconds from the original 3 arc seconds for better visualization at global scale. | km^2 |

'Citation to the paper is adequate if you simply use MERIT DEM. If you asked for help for additional handling/editing of the dataset, or if your research outcome highly depends on the product, the developer would request co-authorship.

- CC-BY-NC 4.0 license: Non-Commercial Use with less restriction.
- ODbL 1.0 license: Commercial Use is OK, but the derived data based on MERIT DEM should be made publicly available under the same ODbL license. For example, if you create a flood hazard map using MERIT DEM and you would like to provide a COMMERCIAL service based on that, you have to make the hazard map PUBLICLY AVAILABLE under OdBL license.
Note that the above license terms are applied to the "derived data" based on MERIT DEM, while they are not applied to "produced work / artwork" created with MERIT DEM (such as figures in a journal paper). The users may have a copyright of the artwork and may assign any license, when the produced work is not considered as "derived data".

请注意，上述许可条款适用于基于MERIT DEM的 "衍生数据"，而不适用于用MERIT DEM创作的 "作品/艺术作品"（如期刊论文中的数字）。当制作的作品不被视为 "派生数据 "时，用户可以拥有艺术品的版权，并可以转让任何许可。
