Mission

Implement dataset upload and metadata extraction for raster and vector data.

Required features

• Upload endpoint for datasets.
• Save original file unchanged.
• Compute checksum.
• Detect raster vs vector.
• Extract raster metadata with Rasterio.
• Extract vector metadata with GeoPandas/Fiona.
• Store metadata in dataset record.
• Generate basic preview for raster if feasible.
• Add tests with small fixtures.

Rules

• Do not require external production datasets for tests.
• Use small test fixtures.
• If GDAL/Rasterio dependency issues exist, document clearly and keep code structured.
• Do not fake metadata.
