This process, which creates a three-dimensional model of the land&#8217;s surface, is not just a preliminary step; it dictates the engineering viability, the budget, and the ultimate timeline of the entire project. Yet, the intense pressure of Vision 2030 deadlines has created a crisis: the slow, dangerous, and low-density methods of the past simply cannot keep pace.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We need a solution that is not just faster, but also more accurate. The answer is the intelligent integration of advanced drone technology.
