GeoData in Elixir?

Okay, geo seams to be able to decode. The felt website also shows, the usecase of working with shape files.

But I haven’t found the the function to open shape files. The geo package shows encoding, decoding of geojson. But it seams to be possible, or does felt use another stack/programming language? Normally I use geopandas in python, or QGIS for watching the files.
Is there a blog or combined reference/resource for geodata projects?
