# S2 Geo Processor Plugin
|
|
|
|
|
|
|
|
|
|
Use the `s2geo` processor to add tag with S2 cell ID token of specified [cell level][cell levels].
|
|
|
|
|
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
|
|
|
|
|
|
|
|

|
## The name of the lat and lon fields containing WGS-84 latitude and
|
|
|
|
|
## longitude in decimal degrees.
|
|
|
|
|
# lat_field = "lat"
|
|
