Power
Technically, you have the power to influence the direction of a massive construction project, all with the survey data you provide to the project's managers. You can mess with the GPS coordinates at will; placing data points in anthills, landfills, and other undesirable locations. You can find ways to drag out projects for someone you don't like, taking three days for a survey that should have taken six hours.
None of this is ethical, and this behavior certainly won't help your career prospects. In fact, this questionable conduct could even affect your surveyor's license. Conclusion: Although you might briefly enjoy this sense of absolute power, the potential consequences just aren't worth it. And you probably couldn't live with yourself.
