Show HN: Isometric SF – A pixel-art map of the SF Bay Area
Hi HN! This post showcases a unique project that transforms 1300 square miles of the San Francisco Bay Area into a cohesive pixel map. The process involves taking Google Photorealistic 3D Tiles and using them to create a pixel map that allows users to explore various famous landmarks, such as Apple Park, Palace of Fine Arts, and UC Berkeley.
The technical aspects of this project revolve around the use of Nano Banana 2 to train a Qwen-Image-Edit 2511 LoRA, which is employed to prototype the style and generation methods. However, for the final map, the authors turned to Qwen to train a Klein 4B LoRA, achieving the desired style at just a quarter of the cost.
More detailed information about the project can be found in the blog post linked above. The creators express their enjoyment of fine-tuning smaller open-source models and invite readers to share their thoughts on the project. The idea for the map was inspired by Isometric NYC.
