I am trying this example with different input files. My aim is to merge the country and point tables into one table using sjoin from geopandas and write to a CSV file. I took a look at 1. When I run the second line of code below, It takes really long time.

  1. My Input point file is about 62kb and my country file is about 8kb is that the reason for the time consumption ?
  2. Is there any other efficient way to write to a CSV? Or is there any mistake in my code below ?
merged_gdf = gpd.sjoin(point_gdf, country_gdf, how="right", op="within")
