使用說明：

'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.

MERIT DEM is licensed under a Creative Commons "CC-BY-NC 4.0" or Open Data Commons "Open Database License (ODbL 1.0)". With a dual license, you can choose an appropriate license for you.

To view a copy of these license, please visit:

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".

By downloading and using the data the user agrees to the terms and conditions of one of these licenses. Notwithstanding this free license, we ask users to refrain from redistributing the data in whole in its original format on other websites without the explicit written permission from the authors.

The copyright of MERIT DEM is held by the developers, 2018, all rights reserved.'

MERIT DEM采用知識共享 "CC-BY-NC 4.0 "或開放數據共享 "開放數據庫許可（ODbL 1.0）"進行許可。通過雙重許可證，你可以選擇適合你的許可證。

要查看這些許可證的副本，請訪問。

CC-BY-NC 4.0許可證。非商業使用，限制較少。

ODbL 1.0許可證。商業使用是可以的，但基于MERIT DEM的衍生數據應在相同的ODbL許可證下公開提供。例如，如果你用MERIT DEM創建了一個洪水災害地圖，并且你想在此基礎上提供商業服務，你必須在ODBL許可證下公開提供該災害地圖。

請注意，上述許可條款適用于基于MERIT DEM的 "衍生數據"，而不適用于用MERIT DEM創作的 "作品/藝術作品"（如期刊論文中的數字）。當制作的作品不被視為 "派生數據 "時，用戶可以擁有藝術品的版權，并可以轉讓任何許可。

MERIT DEM的版權由開發者持有，2018年，所有權利保留。
