lunadem 0.1.0

Production-ready DEM generation toolkit for lunar and planetary imagery.

LunarDEM

LunarDEM is a production-oriented Python library for generating and analyzing Digital Elevation Models (DEM) from lunar and planetary imagery.

It ships with:

• shape-from-shading (SFS) reconstruction
• multi-scale SFS
• plugin-ready ML method scaffolding
• hybrid SFS + ML fusion
• terrain analytics (slope, roughness, curvature, histograms)
• deterministic landing suitability analysis
• geospatial exports (GeoTIFF, OBJ, PLY)
• CLI + Python API + PyPI-ready packaging

Installation

pip install .

Optional extras:

pip install .[viz]
pip install .[ml]
pip install .[docs]
pip install .[dev]

Quick Start (Python API)

from lunardem import generate_dem, ReconstructionConfig

config = ReconstructionConfig(
    output={"output_dir": "output", "base_name": "moon_run"},
)
result = generate_dem("data/moon1.png", method="multiscale_sfs", config=config)
print(result.exports)
print(result.metrics.stats)

Quick Start (CLI)

lunardem generate data/moon1.png --method sfs --output output
lunardem analyze output/reconstructed_dem.tif
lunardem landing output/reconstructed_dem.tif --spacecraft examples/configs/landing.yaml

Public API

• generate_dem(input_data, method, config) -> DEMResult
• analyze_dem(dem_or_path, analysis_config) -> TerrainMetrics
• assess_landing(dem_or_path, landing_config) -> LandingReport

Methods

• sfs: single-scale Lambertian SFS with optimization diagnostics
• multiscale_sfs: coarse-to-fine SFS
• ml: deterministic baseline scaffold with optional torch plugin path
• hybrid: weighted SFS+ML fusion with fallback behavior

Outputs

• DEM array in meters
• GeoTIFF (.tif) with planetary CRS defaults
• 3D mesh (.obj, optional .ply)
• Visualizations (depth_map.png, surface_3d.png) with viz extra
• JSON manifest for reproducibility
