#Applications

• Inspect and decode TIFF 6.0 and BigTIFF metadata, GeoKeys, tiles, strips, and overview layouts.
• Process Sentinel-2/Landsat-style multispectral scenes with NDVI, water, burn, soil, and moisture indices.
• Run raster map algebra, focal filters, resampling, classification, DEM terrain, and hydrology operations.
• Plan deterministic HTTP byte ranges for tiled COG windows before remote tile retrieval.
• Build native command-line workflows or reuse individual packages from MoonBit applications.
