Raster to Hexagon

Transforming raster data into H3 cells

Raster to H3

When to use​

Transforming raster data into H3 cells is useful when you need to:

  • Want to have spatial statistics about a raster (heatmap like visualization)
  • A fast way to run statistics across different disparate datasets by combining them all to hexagons

Code implementation​

We've made a Public UDF Hexagonify_raster_from_url that you can use in your own UDFs or any workflow.

note

To call a public UDF you need to use the prefix UDF_ in front of the name.

This allows you to run this UDF without needing an environment setup on your account.

hex_df = fused.run(
    "UDF_Hexagonify_raster_from_url",
    raster_path="https://s3.amazonaws.com/elevation-tiles-prod/geotiff/4/4/6.tif", 
    stats_type="mean", 
    h3_res=4
)

Raster to hex operation

Example application​

  • DEM_Tile_Hexify Public UDF.
    • This UDF takes a Raster Tile from an open S3 bucket containing an elevation model and converts a tile into H3 on the fly
