Map service ComputeDistance method

Calculates the distance between two points in a map (data frame).

ComputeDistance(string MapName, Point FromPoint, Point ToPoint, esriUnits Units)

Parameter	Description
MapName	The name of the data frame in the map service.
FromPoint	The starting point in the line. The spatial reference is assumed to be the same as the data frame.
ToPoint	The ending point in the line. The spatial reference is assumed to be the same as the data frame.
Units	The unit of measure in which the distance between two points will be returned.

Return Value

A double value representing the distance between the FromPoint and ToPoint in the Units defined.

Remarks

The MapName parameter references a data frame name in the map service associated with the map service proxy. The data frame must have a valid spatial reference. The coordinates defined for the both points in the line assume the data frame's spatial reference.

Examples

C#

MapService_MapServer mapservice = new MapService_MapServer();

mapservice.Url = "http://localhost:6080/arcgis/services/MapService/MapServer";

 

string mapname = mapservice.GetDefaultMapName();

wsmap.PointN pnt0 = new PointN();

pnt0.X = -120.0;

pnt0.Y = 30.0;

 

wsmap.PointN pnt1 = new PointN();

pnt1.X = -110.0;

pnt1.Y = 35.0;

double distance = mapservice.ComputeDistance(mapname, pnt0, pnt1, esriUnits.esriMiles);

VB.NET

Dim mapservice As MapService_MapServer = New MapService_MapServer()

mapservice.Url = "http://localhost:6080/arcgis/services/MapService/MapServer"

 

Dim mapname As String = mapservice.GetDefaultMapName()

Dim pnt0 As wsmap.PointN = New PointN()

pnt0.X = -120.0

pnt0.Y = 30.0

 

Dim pnt1 As wsmap.PointN = New PointN()

pnt1.X = -110.0

pnt1.Y = 35.0

 

Dim distance As Double = mapservice.ComputeDistance(mapname, pnt0, pnt1, esriUnits.esriMiles)

Java

String serviceURL = "http://localhost:6080/arcgis/services/MapService/MapServer";

MapServerBindingStub mapService = new MapServerBindingStub(serviceURL);

 

String mapName = mapService.getDefaultMapName();

 

PointN pnt0 = new PointN();

pnt0.setX(-120.0);

pnt0.setY(30.0);

 

PointN pnt1 = new PointN();

pnt1.setX(-110.0);

pnt1.setY(35.0);

 

double distance = mapService.computeDistance(mapName, pnt0, pnt1, EsriUnits.esriMiles);

System.out.println("Distance: " + distance);
