LOCATING EQUIPMENT FOR AND METHODS OF SIMULATING LOCATE OPERATIONS FOR TRAINING AND/OR SKILLS EVALUATION
First Claim
1. A method for simulating a locate operation to locate the presence or absence of an underground facility in a dig area, comprising:
- loading selected virtual facilities data into a virtual facilities memory in locate equipment, the selected virtual facilities data including geographic coordinates in the dig area and corresponding simulated signal values;
sensing current geographic coordinates of the locate equipment with a location tracking device;
accessing simulated signal values in the virtual facilities memory according to the sensed geographic coordinates of the locate equipment; and
indicating the simulated signal values to a user.

Abstract
Training systems for and methods of simulating locate operations are provided for training and/or skills evaluation. Facility locating equipment, such as on-site computers and/or locate receivers, may include modules for electronically simulating locate operations. Locating equipment including simulation modules may be used, for example, in locate technician training processes and/or for updating and/or evaluating the skills of locate technicians. In particular, a simulation module is provided for electronically generating “virtual” facilities, the presence and/or absence of which may be indicated to a locate technician during, for example, a training exercise. The actions of the locate technicians with respect to dispensing marking material that corresponds to the presence and/or absence of the virtual facilities are electronically captured, stored, and evaluated.
