Calculate the distance between two points in a map (data frame).
ComputeDistance(string MapName, Point FromPoint, Point ToPoint, esriUnits Units)
|
Parameter |
Description |
|
MapName |
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 of 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.
