I can understand it when we talk about human, but what is the meaning of node in SEIR state? node contain some humans, in that node ,I believe, peoples can be in different states, so how the state of a node is calculate?
thank you

I have tried to explain below:

every human has a home location;
every home location has a corresponding node; (this is the resolution of output from simmobility long term)
now, every node will have lots of people, let us say 2000
for better plotting visibility in Kepler and having lots of flexibility in Kepler we assigned those 2000 humans random locations around their home node
in order to get the state of a node, we can define it as the state of the majority of the humans whose home location is that node <this last bullet is not done in this file, this we did while plotting in kepler by selecting the majority state as the state of the node> if you want to directly save the node id location, you can follow as mentioned below:

If you want to instead all the 2000 humans to exactly the same lat-lon as the node, you can set the randomness to 0 by replacing 0.001 by 0 in these lines np.random.normal()*0

does that answer your question?
