Introduction

Heightcraft is a high-performance, AI-powered heightmap generation and upscaling tool designed for GIS professionals, Game Engineers, and Researchers.

It streamlines the pipeline from raw data (3D Meshes, LiDAR Point Clouds, or Low-Res Images) to high-quality, high-precision heightmaps ready for use in game engines (Unreal, Unity) or GIS software (QGIS, ArcGIS).

Key Features​

🚀 AI-Powered Upscaling​

Transform low-resolution heightmaps into crisp, high-res/high-detail terrains using advanced AI models. Optionally increase original bit depth (e.g., 8-bit to 16-bit) to eliminate stepping artifacts.

📡 LiDAR Support​

Process massive .las and .laz point cloud files efficiently. Heightcraft uses a streaming, chunked processing pipeline to handle gigabytes of data with minimal memory footprint.

🏔️ 3D Mesh to Heightmap​

Convert .gltf, .glb, .obj, .stl, .ply, and other 3D mesh formats into heightmaps. Supports large models with automated chunking and memory management.

🎯 Precision & Formats​

  • 32-bit Float TIFF: Full precision for scientific and GIS applications.
  • 16-bit PNG/TIFF/RAW: Standard for game engines.

The Pipeline​

Who is this for?​

  • Game Developers: Automate terrain generation pipelines.
  • GIS Specialists: Convert LiDAR data to DEMs efficiently.
  • Researchers: Process large datasets for terrain analysis.
