Nice! I think it's a good initiative to organize more local types of meetups in the geospatial community. Geospatial experts are a bit too few and inbetween to bump into many of them on a regular day, so anything that gets these people together is a big win.

As a side note to HN readers, geospatial is a super interesting application/ specialization that you might consider getting into if you're looking to add more meaning and purpose to your programming or tech career. You're often working to improve quality of life for someone, there are lots of interesting companies, people are generally super friendly and accessible, and there's a wealth of interesting problems and challenges to work on. My 2 cents!
