属性说明数据类型
travelDirection
(只读)

The direction of travel to or from the facilities. This property returns the following keywords:

  • TRAVEL_FROM
  • TRAVEL_TO

String
defaultBreaks
(只读)

Service Area Solver only.

A space-separated string of impedance values indicating the extent of the service area to be calculated.

String
serviceAreaPolygons
(只读)

The type of polygons to be generated. This property returns the following keywords:

  • NO_POLYS
  • SIMPLE_POLYS
  • DETAILED_POLYS

String
serviceAreaPolygonsType
(只读)

Indicates how to create concentric service area polygons when using multiple break values. This property returns the following keywords:

  • RINGS
  • DISKS

String
mergeSimilarRanges
(只读)

Indicates how to merge polygons that share similar break values when generating polygons for multiple facilities. This property returns the following keywords:

  • NO_MERGE
  • NO_OVERLAP
  • MERGE

String
exclusionSources
(只读)

A semicolon-separated list of network sources to be excluded when generating the polygons.

String
trimPolygons
(只读)

Indicates if the resulting polygons will be trimmed to be within a specified distance. This property returns the following keywords:

  • TRIM_POLYGONS
  • NO_TRIM_POLYGONS

String
trimDistance
(只读)

A space-separated string indicating the distance and units within which the polygons are trimmed.

String
serviceAreaLines
(只读)

The type of lines to be generated based on the service area analysis. This property returns the following keywords:

  • NO_LINES
  • TRUE_LINES
  • TRUE_LINES_WITH_MEASURES

String
serviceAreaLinesType
(只读)

Indicates if overlapping lines are generated when computing the service area lines. This property returns the following keywords:

  • OVERLAP
  • NON_OVERLAP

String
splitLinesAtBreaks
(只读)

Indicates if the service area lines will be split at the boundaries of the breaks. This property returns the following keywords:

  • SPLIT
  • NO_SPLIT

String
includeNetworkSourceFields
(只读)

Indicates if additional fields are added to the service area lines to hold information about the underlying source features traversed during the analysis. This property returns the following keywords:

  • NO_LINES_SOURCE_FIELDS
  • LINES_SOURCE_FIELDS

String
timeOfDay
(只读)

Indicates the time to depart from or arrive at the facilities. The interpretation of this value depends on whether travel is toward or away from the facilities. It represents the departure time if the travelDirection property is set to TRAVEL_FROM and represents the arrival time if the travelDirection property is set to TRAVEL_TO.
