geo.ST_Contains() function
The geo.ST_Contains() function is experimental and subject to change at any time.
By using this function, you accept the risks of experimental functions.
The geo.ST_Contains() function tests if the specified region contains the specified
geographic information system (GIS) geometry and returns true or false.
import "experimental/geo"
geo.ST_Contains(
region: {lat: 40.7, lon: -73.3, radius: 20.0},
geometry: {lon: 39.7515, lat: 15.08433}
)
// Returns false
Parameters
region
The region to test. Specify record properties for the shape. See Region definitions.
geometry
The GIS geometry to test. Can be either point or linestring geometry. See GIS geometry definitions.
Examples
Test if geographic points are inside of a region
import "experimental/geo"
region = {
minLat: 40.51757813,
maxLat: 40.86914063,
minLon: -73.65234375,
maxLon: -72.94921875
}
data
|> geo.toRows()
|> map(fn: (r) => ({
r with st_contains: geo.ST_Contains(region: region, geometry: {lat: r.lat, lon: r.lon})
}))
Test if tracks are inside of a region
import "experimental/geo"
region = {
minLat: 40.51757813,
maxLat: 40.86914063,
minLon: -73.65234375,
maxLon: -72.94921875
}
data
|> geo.toRows()
|> geo.asTracks()
|> geo.ST_LineString()
|> map(fn: (r) => ({
r with st_contains: geo.ST_Contains(region: region, geometry: {linestring: r.st_linestring})
}))
