S2 Geo Processor Plugin

Use the s2geo processor to add tag with S2 cell ID token of specified cell level. The tag is used in experimental/geo Flux package functions. The lat and lon fields values should contain WGS-84 coordinates in decimal degrees.

Configuration

[[processors.geo]]
  ## The name of the lat and lon fields containing WGS-84 latitude and longitude in decimal degrees
  lat_field = "lat"
  lon_field = "lon"

  ## New tag to create
  tag_key = "s2_cell_id"

  ## Cell level (see https://s2geometry.io/resources/s2cell_statistics.html)
  cell_level = 11

Example

- mta,area=llir,id=GO505_20_2704,status=1 lat=40.878738,lon=-72.517572 1560540094
+ mta,area=llir,id=GO505_20_2704,status=1,s2_cell_id=89e8ed4 lat=40.878738,lon=-72.517572 1560540094
