Hola Mario,
thanks for your message. I appreciate you trying to keep things in order and by the law. The last time we spoke, I kept thinking about how to better help the OSM community. The way we found was to change our license terms for most of our data. Formerly, our published data was under CC BY-SA License, but now I’m updating most of the datasets to Attribution 4.0 International (CC BY 4.0) License.
Basically, this means, anyone may use the data even for commercial purposes and give credit to the source (STRI GIS Laboratory 2021).
For the BCI Trails layer, I just updated the license to allow the requested use. If you find another layer which requires license changes, let me know.
Saludos from a very sunny La Chorrera,
MJ
