Graphical aids for surveying
First Claim
1. A graphical display configured to provide at least one graphical symbol indicative of a separation value between a first and second location, the separation value relating to a value selected from a group comprising a distance between the first and second location and subtended between the first and second location at a predetermined reference point, wherein the graphical symbol is resolved into components comprising at least one pair of opposing arrows and at least one arrow of the at least one pair of opposing arrows denotes a corresponding separation value component.

Abstract
The present invention provides a method and apparatus configured to provide graphical symbols indicative of a separation value between a first and second location, measured from a predetermined reference point. In one embodiment, the separation value relates to at least one of the direct distance between said first and second locations and the angle subtended between said first and second location at the said predetermined reference point. In one embodiment, the separation value may be resolved into mutually orthogonal components. An alpha-numeric display may also be included and configured to represent the magnitude of said separation values.

13. A method of determining and displaying a separation value between a first and second location using a measurement device, as observed from a predetermined reference point, the method comprising:
-
determining the location of the measurement device;
inputting the location of one of either the first location or the second location;
determining the distance and angular orientation of the other of the first location or second location with respect to a reference point;
calculating and displaying a separation value as at least one first graphical symbol; and
displaying at least one second graphical symbol if the separation value is less than a predetermined threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system configured to provide at least one graphical symbol indicative of a separation value between a first and second location, the separation value relating to a value selected from a group, the system comprising:
-
a distance device and an angular measuring device configured to determine a separation value between a first and second location a graphical display coupled to the distance and angular measuring device, the graphical display capable of providing graphical symbols indicative of a separation value related to a value selected from a group comprising a direct distance between the first and second location and subtended between the first and second location at a predetermined reference point, wherein the graphical symbol is resolved into components comprising at least one pair of opposing arrows and at least one arrow of the at least one pair of opposing arrows denotes a corresponding separation value component. - View Dependent Claims (24, 25, 26, 27)

28. A computer readable medium containing instructions which when executed in a processing system performs a process for determining and displaying a separation value between a first and second locations comprising:
-
determining a location of a measurement device;
receiving a location of one of either the first location or the second location;
determining a distance and angular orientation of the other of the first location or second location with respect to a reference point;
calculating and displaying a separation value as at least one first graphical symbol; and
displaying at least one second graphical symbol if the separation value is less than a predetermined threshold. - View Dependent Claims (29, 30, 31, 32, 33, 34)
