Method and system for surveying and modeling a site
First Claim
1. A surveying system for generating a computer model of a physical site, the system comprising:
- a survey measurement device for determining a location of a selected feature relative to the survey measurement device; and
a computer-aided drafting (CAD) module for modeling the physical site, the CAD module, including a CAD application program installed on a computer for receiving from the survey measurement device data related to the location of the selected feature, and for creating a corresponding object in the computer model, and a bidirectional communication interface between the CAD application program and the survey measurement device for communicating commands from the CAD application program to the survey measurement device and for communicating the data related to the location of the selected feature from the survey measurement device to the CAD application program.

Abstract
A method of using a computer to control a survey measurement device for determining a virtual location of a virtual model object corresponding to the feature. Initially, the survey measurement device is directed at the feature. Then the computer issues a command to the survey measurement device to determine coordinates of the feature relative to the survey measurement device and receives from the survey measurement device the relative coordinates of the feature. The computer then records the relative coordinates into a corresponding virtual location in the model and establishes at the virtual location the virtual object corresponding to the feature.

11. A computer-aided drafting (CAD) module for a surveying system, the surveying system having a survey measurement device connected to a computer running the CAD module, the CAD module comprising:
-
a CAD application program for creating a model of a site including objects representing features of the site; and
a bi-directional communication interface for enabling the CAD application program to initiate measurement of a location of a feature at the site by the survey measurement device, and for enabling the survey measurement device to communicate data related to the location of the feature to the CAD application program. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A surveying method using a survey measurement device connected to a CAD module, the method comprising steps of:
-
sending a trigger command from the CAD module to the survey measurement device to initiate measurement of a location of a feature at a survey site by the survey measurement device;
receiving from the survey measurement device the location of the feature; and
establishing, at a corresponding location in a model of the site, an object corresponding to the feature. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method of marking features at a site corresponding to objects in a computer model, the method comprising:
-
selecting, through interaction with a graphical user interface associated with a computer-aided drafting (CAD) module, an object in a computer model of the site pre-loaded into the CAD module, the object corresponding to a feature at the site;
transmitting real world coordinates of the feature from the CAD module to a survey measurement device;
commanding the survey measurement device to indicate a location of the feature; and
marking the location.
