lunadem 0.2.1

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

lunadem

lunadem is a Python library for generating and analyzing Digital Elevation Models (DEM) from lunar and planetary images.

PyPI release page:

https://pypi.org/project/lunadem/0.1.1/

Install

pip install lunadem

Note: in code, current module import is lunardem.

Main Capabilities

• DEM generation from image input (PNG, JPG, TIFF, GeoTIFF)
• Multiple methods: sfs, multiscale_sfs, ml, hybrid
• Terrain analytics: slope, roughness, curvature, elevation statistics, histogram summaries
• Landing suitability: safe/unsafe masks, hazard filtering, score and safe-area summary
• Exports: GeoTIFF DEM, OBJ/PLY mesh, visualization images, JSON run manifest

Core Functions (Python API)

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

Quick API Example

from lunardem import ReconstructionConfig, generate_dem

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

CLI Usage

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
