CalculateIsolines

Source: src/AWS/GeoRoutes/CalculateIsolines.ts

Runtime binding for geo-routes:CalculateIsolines — compute areas reachable within time or distance thresholds from a point (isochrones / isodistances), e.g. “everywhere within a 30-minute drive”.

geo-routes is a standalone, pay-per-call Amazon Location API with no resource to manage: the binding takes no arguments and grants the function geo-routes:CalculateIsolines. Requests and responses are raw distilled types (Origin is a [longitude, latitude] pair).

Calculating Isolines

Provide the CalculateIsolinesHttp implementation layer on the Function effect (.pipe(Effect.provide(AWS.GeoRoutes.CalculateIsolinesHttp))), bind in the init phase, then call the client at runtime.

// init
const calculateIsolines = yield* AWS.GeoRoutes.CalculateIsolines();

// runtime — coordinates are [longitude, latitude]; thresholds in seconds
const result = yield* calculateIsolines({
  Origin: [-122.339, 47.61],
  Thresholds: { Time: [600] },
  TravelMode: "Car",
});
const polygons = result.Isolines[0]?.Geometries;
