I tried to block the name of the survey truck to protect the company name and I didn’t show their faces because I didn’t want them to possibly lose their jobs. They claimed they don’t take curvature into account except for large road construction but yet they do use sea level as their base line when doing much larger jobs. It seems as though they are not positively sure about these larger jobs but they did admit the smaller jobs curvature isn’t even considered. IMAGINE THAT !!!!!!!
