WebGL allows for fast graphics rendering on most web browsers, but also inherits undesired traits from from its videogame legacy. One of these traits is low numerical precision on integer and floating point operations.
Tiling datasets has allowed tiles (both raster and vector) to dominate web applications since tiles can easily overcome these problems. This talk will explore the opposite: possible ways to overcome numerical precision challenges in untiled datasets, as well as the dreaded antimeridian artefacts in coordinate systems which wrap around the globe.
This will include a brief introduction to floating point, and live demos (showing how GIS data with/without artefacts looks like)
