Make a Map Tile Server in seconds

This example works best in Workbench

@fused.udf
def udf(
   bounds: fused.types.Bounds,
   path: str="s3://fused-asset/data/tiger/state/tl_rd22_us_state 1pct.parquet"
):
   import geopandas as gpd
   
   df = gpd.read_parquet(path)
   df = df.cx[bounds[0]:bounds[2], bounds[1]:bounds[3]]
   df['area'] = df['geometry'].area.round(2)
   return df

• Switch to using a Tile UDF
• Save your UDF
• Create a new shared token
• Copy the HTTPS endpoint

Edit the tile coordinates to use {z}/{x}/{y}:

https://.../run/tiles/{z}/{x}/{y}?dtype_out_vector=parquet

Connect this anywhere to deliver a map tile server!
