Show HN: Isopolis – Isometric Pixel Map of SF | Hacker News

An HN maker built Isopolis, an isometric pixel-art map of San Francisco.

The project used Google Photorealistic 3D Tiles, streamed and rendered with three.js.

AI helped create the style by generating and curating training images for a consistent pixel-art look.

It demonstrates a practical workflow for turning geospatial 3D data into stylized maps using public data, web graphics, and AI.

The project also highlights free US LIDAR data and the effort required to produce high-quality training data.
