DESCRIPTION:Workflow demonstration converting 20GB+ raster datasets like GE
 DTM30 global DEM to H3 hexagonal grids at resolution 12. Complete pipeline
  uses GDAL\, DuckDB\, and GeoParquet for QGIS visualization. Benefits incl
 ude eliminated projection boundaries\, consistent global coverage\, and sc
 alable OGC REST API with O(1) retrieval performance for modern cloud-nativ
 e workflows
