Nadir camera rigging that utilizes more than 2 lenses to capture 360º footage, the nadir location follows the same logic as the astronomical definition in that it is located opposite of the zenith, or in the same direction as the gravitational pull in relation to the camera rigging. Nadir The nadir (, ; from / ALA-LC: "naẓīr", meaning "counterpart") is the direction pointing directly "below" a particular location; that is, it is one of two vertical directions at a specified location, orthogonal to a horizontal flat surface there. Since the concept of "being below" is itself somewhat vague, scientists define the
Point-to-point laser technology Point-to-point laser technology Most commonly used for as-built and existing conditions documentation or converting the built environment into a digital format. PPLT has many benefits in creating BIM or (CAD) models. Entering data directly into a CAD- or BIM-enabled work station allows a user or 'surveyor' to capture and confirm a building's geometry on site. This effectively builds a digital model of a building while it is being measured enabling not only speed but accuracy. Additionally, building in real time can eliminate the need for revisits and also minimizes the need for future interpretation and manipulation of measurements and data
