name: gdal-rastertile description: Decide when raster tiling is needed and how to structure GDAL-based pipelines.

GDAL Raster Pipeline

When to use

• Input is raster imagery (GeoTIFF etc.) and user needs web tile visualization.
• Reprojection, nodata handling, or zoom-range control is required.

Core knowledge

• Typical steps: inspect -> optional nodata normalization -> reprojection -> tile generation.
• Output should include both artifacts and a preview map.

Recommended workflow

1. Capture source metadata and processing parameters.
2. Apply necessary raster transforms.
3. Generate web-consumable tiles.
4. Provide index.html preview and links to intermediate artifacts.

Output expectations

• Reproducible pipeline artifacts.
• Clear fallback message when toolchain/runtime is unavailable.
