I’m a newbie to Julia agents.jl.  
How hard is to develop models in agents.jl requiring shape files and multi-agents using locations in a projected coordinate system? any experiences that can be compared to Gama

Thanks

Hi,

couldn’t you just use a `ContinuousSpace` instance? You can use the projections whenever you `move_agent!` to be sure that it is moved to its appropriate location.

There is no explicit support for shape files or for continuous coordinate systems outside the Euclidean space at the moment, but making a new space type is rather straightforward: [Developer Docs · Agents.jl](https://juliadynamics.github.io/Agents.jl/stable/devdocs/#Creating-a-new-space-type).

(I do not know about Gama, hope someone else can comment on that)

I’ll check that space. Thanks
