⚡ Convert GeoTIFF to Cloud Optimized GeoTIFF

Choose your data type below for optimized conversion settings.

Multi-band RGB orthomosaic imagery

Bilinear or cubic work best for aerial imagery

JPEG provides excellent compression for RGB photos

Leave blank to auto-generate filename

💡 DEM Conversion Tips:
  • Use LZW compression (lossless) to preserve elevation accuracy
  • Enable auto-detect NoData to avoid conversion errors
  • For bathymetric DEMs (underwater), nodata is often -32767
  • Bilinear resampling creates smooth elevation surfaces

Single-band elevation data (DEM/DSM/DTM/Bathymetry)

Bilinear smooths elevation nicely for visualization

Always use lossless compression to preserve elevation accuracy

⚠️ Must match your source file's nodata value! Check with: gdalinfo yourfile.tif
Common values: -9999, -32767, -32768, 0. For bathymetric DEMs, often -32767.

✅ Let the converter read the nodata value from your source file automatically

📦 Batch Conversion

For converting multiple files, use the command-line batch converter:

python make_cog_batch.py --src-dir "input" --dst-dir "data"
