Farmier has a file upload size limit of 100 mb, so I don’t think this is a feasible approach. I’m not set up to offer hosting of large image sets like this. I do not host the MapBox or Google satellite imagery on my servers - these come from MapBox/Google servers, and are just referenced by the map layer in farmOS. And technically I have API keys with those providers that measure how much traffic is used and I pay extra if I go over their (generous) free levels. Hosting large imagery directly on my server would be a different set of calculus for me, which I would need to think about with regard to pricing etc. In all honesty I’m not interested in exploring that, since there are so many other options available already, and it would be another thing I need to manage.
So if you are working with imagery that large then perhaps S3 would be the best option. If you’re unfamiliar, S3 is Amazon AWS’s “simple storage service” which is aimed specifically at hosting static files that do not change frequently (like images). You would pay Amazon for the cost of storage and traffic directly.
