# 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
|
|
|
|
```toml
|
|
[[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
|
|
|
|
```diff
|
|
- 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
