In this public meeting, Joanne Cheng presented some ideas and practices for drawing geographical maps using Clojure and R.

It was a special meeting since we explicitly invited R users who are new to Clojure to join us and listen. We plan to have more meetings of this kind in the future.

In this public meeting, we had a talk from our friend Will Cohen, an urban planner from Boston.

Will is the maintainer of the Geo library and the author of Ovid and Aurelius.

https://github.com/willcohen/ovid
https://github.com/willcohen/aurelius

The talk began with a general introduction to GIS and geospatial analysis, mainly in the context of urban planning. Then, Will went through the history, the state of the art, and the vision for the future of GIS in Java, Clojure, and Clojurescript.

In the discussion, several members shared their problems and practices. We also discussed the possible next steps in building the Clojure GIS stack, and possible ways to collaborate.

Konrad Kühne told about Datahike, and the Datalog ecosystem, with a live demo of using Datalog to work with data.

Followup comment by Konrad Kühne:
After watching the Q&A again, I noticed that I understood a question about recursion not completely. I thought the question was about unbounded recursion like in Prolog which datahike doesn't support. But simple recursions can be expressed like in the following example: https://gist.github.com/kordano/39398882d99b46ebd61155fcb566872a

Nextjournal runnable notebook with some of the live demos in the talk, transcribed by David Schmüdde:

Unfortunately, a little bit of the live demo did not work (it turns out that the live-reload! functionality is only broken on 1.6.0-alpha3, but still works on 1.6.0-alpha2).
