Descrição
wth
metros
Largura do canal do rio nas linhas de centro do canal. A largura do canal do rio é calculada pelo método descrito em [Yamazaki et al. 2012, WRR], com algumas melhorias/mudanças no algoritmo. Essa banda foi ampliada de 3 para 18 segundos de arco para melhorar a visualização em escala global.
upa

metros
Área de drenagem a montante (área de acúmulo de fluxo). Essa banda foi ampliada de 3 para 18 segundos de arco para melhorar a visualização em escala global.
Termos de Uso
Termos de Uso
A citação do artigo é adequada se você usar apenas o MERIT Hydro. Se você pediu ajuda para processar/editar o conjunto de dados ou se o resultado da pesquisa depende muito do produto, o desenvolvedor vai pedir coautoria.
O MERIT Hydro é licenciado de acordo com uma licença Creative Commons "CC-BY-NC 4.0" ou Open Data Commons "Open Database License (ODbL 1.0)". Com uma licença dupla, você pode escolher a mais adequada para você.
Licença ODbL 1.0:
o uso comercial é permitido, mas os dados derivados com base no MERIT Hydro precisam ser disponibilizados
publicamente sob a mesma licença ODbL. Por exemplo, se você criar um mapa de risco de enchente usando o MERIT Hydro e quiser fornecer um serviço COMERCIAL com base nele, precisará disponibilizar o mapa de risco PUBLICAMENTE sob a licença OdBL.
Os termos de licença acima são aplicados aos "dados derivados" com base no MERIT Hydro, mas não ao "trabalho produzido / arte" criado com o MERIT Hydro (como figuras em um artigo de revista). Os usuários podem ter um
direito autoral da arte e atribuir qualquer licença quando o trabalho produzido
não for considerado como "dados derivados".
Ao fazer o download e usar os dados, o usuário concorda com os termos e condições da licença. Apesar dessa licença sem custo financeiro, pedimos aos usuários que
não redistribuam os dados por completo no formato original em outros
sites sem a permissão explícita por escrito dos autores.
