Dear researchers

In my subject, I work on the characterization of the Moroccan marine microbiota by metagenomics under the discipline of microbial ecology.

During the sampling, we could not have all the in situ measurements of the Physico-chemical parameters of the studied microbiome. That's why we had recourse to the extraction of spatial data from the NASA website to complete.

my question is: do we have the right to combine our own data with those of a database to analyze them? ethical and copyright aspects. since these data are submitted to the public with open access.
