geo.strictFilter() function

geo.strictFilter() is experimental and subject to change at any time.

geo.strictFilter() filters data by latitude and longitude in a specified region.

This filter is more strict than geo.gridFilter(), but for the best performance, use geo.strictFilter() after geo.gridFilter(). Input rows must have lat and lon columns.

Function type signature
(<-tables: stream[{B with lon: D, lat: C}], region: A) => stream[{B with lon: D, lat: C}] where A: Record

For more information, see Function type signatures.

Parameters

region

(Required) Region containing the desired data points.

Specify record properties for the shape.

tables

Input data. Default is piped-forward data (<-).

Examples

Strictly filter data to a specified region

import "experimental/geo"

data
    |> geo.strictFilter(region: {lat: 40.69335938, lon: -73.30078125, radius: 50.0})

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
