Skill: Raster Pipeline

Use this skill for GeoTIFF/raster metadata, clipping, tiling, band handling and remote-sensing indices.

Raster rules

• Preserve georeferencing metadata.
• Never drop CRS silently.
• Keep raster-derived outputs traceable to source dataset and parameters.
• Use deterministic tile naming.
• Store heavy outputs under documented storage roots, not random folders.
• For V1, prefer metadata and small fixtures over heavy real rasters.

Operations checklist

• Validate raster readable.
• Extract CRS, bounds, transform, dimensions, band count, dtype.
• Clip by area where requested.
• Generate tiles with configured tile size and overlap.
• Preserve mapping from tile pixels to map coordinates.
• Emit metadata JSON for downstream services.
• Add tests with tiny raster fixtures when possible.

Completion report fields
