Small preview is rendered client-side for quick validation only (full COG conversion uses GDAL commands you can run).
Experimental: client‑side COG (WASM) coming soon

COG Validator
Run Analyze to see COG checks.
Conversion options (gdal_translate)
Overviews are internal (required for COG).
Target EPSG
If provided, a gdalwarp step will be added before COG creation.
Suggested GDAL commands
# Run Analyze first, then Build commands to generate a reproducible script. Map Preview
Notes:
- COG requires: tiling, internal overviews, and HTTP-friendly layout (IFD/tiles sorted).
- Use DEFLATE + PREDICTOR=2 for DEMs, JPEG for 8‑bit RGB, ZSTD for large datasets.
- Client preview uses a downsampled view for speed; the final COG is produced via GDAL commands.
