I'm a student trying to upskill in geospatial/compsci. What kinds of projects could you make with all of this? Any good starting points you'd recommend?
Not OP, but almost anything where "a map" is the output will be a hugely big learning opportunity for you. Static maps, print-quality maps, interactive web maps -- the experience of building any of those will bring lots of learning. (That's how I got started.)
