GPS coordinates in Milestone are stored an X,Y order in the format "POINT (X Y)".
As such, if you have a latitude and longitude value, you must reverse them and
format them properly for Milestone to accept the new GisPoint value.
In some cases, the GisPoint property can have a third value representing altitude
or elevation. This is expressed in the format "POINT (X Y Z)".
If the Coordinate object, Coordinates string, or Altitude value are provided, then
the cmdlet will output a three-part GisPoint value.
This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
