XIAO AN
3D Geospatial Engineer
Turning the real world into computable, renderable 3D maps. Focused on 3D rendering, GIS geometry and HD map data production. Currently a Senior Map Engineer at Amap.
I'm XIAO AN, a 3D geospatial engineer. I focus on rendering engines, GIS geometry, 3D modeling and HD map data production.
I like thinking about rendering, geometry and data production as one system: how data is organized, how geometry is computed, and how it finally renders and responds.
This site is where I document engineering practice, keep technical notes and publish a few spatial utilities.
01 · Capabilities
Problems I care about
I do not aim to do everything. I care about connecting data, algorithms, rendering and delivery into one working system.
GIS Geometry
Spatial analysis, geometry editing, booleans, skylines, cross-sections, pipelines and flood simulation.
HD Map & 3D
HD map production tools, semi-automated 3D model production, quality checks and tooling.
Engineering
TypeScript / Node.js / data production systems / tooling.
