JuliaCon 2026

Global grid systems (DGGS), or non-planar grids, are the new hotness - but how can you get data onto them and analyze? In this talk, we'll show the high-level way to do this, which packages you'll need, as well as how to handle issues like geometries on the boundaries of faces, regridding error, and more.

In all likelihood you are familiar with DGGS already - in simulation, tripolar and cubed-sphere grids are common, as are HEALPIX and other formulations.

I've been talking about this for the last two years - but GeometryOps.jl is now finally on the sphere! This talk will give a brief update about GeometryOps with a focus on how the spherical capabilities have materialized, both in native Julia and by calling Google's s2 library. We'll also mention some new cool downstream applications, like ConservativeRegridding.jl and SphericalSpatialTrees.jl, and specifically how they relate to GeometryOps.

The Julia ecosystem for handling geospatial data and analysis is growing and improving. This is a session for anyone interested in geo in Julia to meet package contributors and users to discuss future direction and collaboration efforts.

In this community building session we aim to:

• Hear what people are doing in Julia and Geo
• Develop group goals and common understanding for ecosystem coherence
• Uncover gaps and rough edges in the ecosystem
• Lower the barrier to getting involved

A rough program:

• Introductions: what are you using Julia for, in three words
• Show and tell: share your geo packages and projects that don't have their own JuliaCon talks
• The good, the bad and the ugly in Julia geospatial: a constructive session of gripe-driven development
• Slido poll with questions on datasets, pain points, nice things, integrations, major wishes for the ecosystem

Building and understanding complex models is easier when you can see them come to life. At JuliaHub, we have been creating interactive dashboards that show simulation results, allow live, interactive analysis, and some which even show real world data, for quite some time now. In this talk, I will go through some of the paradigms we've developed and how those have played out, as well as showing some cool examples for inspiration.

An hour for users of Makie.jl to gather, show off cool plots, and talk about the state of the Makie ecosystem!

The world of AI agents is changing constantly - every couple of weeks, it seems there is some new thing. In this talk, I'll try to sum up the current state of the art when using AI agents with Julia - from which agents to use, MCP servers, skills and whatever else comes up between now and then. If you have only dipped your toes into using AI with Julia so far, this talk is for you!
