Show HN: TerrainSR – fast, realistic heightmap upscaling model
Summary
TerrainSR is a model that generates higher-detail terrain height data from lower-detail input, trained on 100m to 10m pairs. It runs fast on an RTX 4070, producing 50x50km patches from 100m data in under 1 second, and supports Python/PyTorch usage with a straightforward example workflow. The model is Apache 2.0 licensed and targets real-time terrain generation for gaming and simulations, with detailed usage instructions, inputs/outputs, and licensing notes, along with caveats about artifacts and data sources.
