There's a lot of data out there that is mapped in HEALPix format, like the ERA5 global climate and weather data. And while DGGS formats are nothing new, visualizing them has traditionally required desktop tools and offline workflows.

Taking advantage of the latest web technologies (namely deck.gl) we decided to explore this uncharted territory and build an interactive HEALPix viewer that runs entirely in the browser. This opens the door to craft unique and engaging experiences for exploring HEALPix data and perform analysis. Visualizing temporal data can become as simple as hitting a play button, allowing users to discover and study patterns previously only accessible to sophisticated tools.

In this talk I'll share our journey into bringing HEALPix to the web while showing the potential this new technology has to change how HEALPix data is accessed and explored.
