Parameters of a reachability computation (calculateReachability).

Inherits from RequestBase.

Field name

Type

Default value

Comments

resources

Resource

 

Resources with their coordinates used for computations. If the resources have a special speed profile, use VehicleResource.

Also supports AirVehicleResource, to compute a beeline reachability (e.g. of a helicopter).

limit

Double

 

Max. distance (in meters) or travel time (in seconds) (depending on optimization), used for reachability.

optimization

RoutingOptimization

Time

Optimization (minimal time or way), used for routing

defaultRoadwaySystemParameters

RoadwaySystemParameters

default values

Vehicle and street parameters

(Ignored for resources of type VehicleResource.with valid roadwaySystemParameters field)

defaultAirwaySystemParameters

AirwaySystemParameters

default values

Air way speed parameters for AirVehicleResources without a valid airwaySystemParameters field.

isocroneAreaResolution

Integer

10000

Resolution of the reached area raster in raster cells. 0 for no area computations.

interspaceVelocitiy

Double

2.0

Velocity that is assume between streets when calculating the reached area

includeReachedRoadsCoordinates

Boolean

true

Include coordinates of the reached roads in response.

investigationAreaWkt

String

null

Area (polygon or multi-polygon) of the study area as a WKT (Well Known Text). When this area is passed, an inverse reachability is calculated: the unreachable areas and road sections within the given area.

If not specified (null), the normal availability is calculated.
