Photogrammetry is an incredibly powerful tool for capturing and recording the size, shape and condition of an existing structure. By allowing an architect to create an intelligent “point cloud” & a three dimensional wire frame model of an existing building from photographs off site, this technology provides a safe and economical means to measure and draw even the most complicated structures.

While the most common application of photogrammetry in architectural work is to measure and draw hard-to-access elevations, this technology also provides an excellent way to prepare plan drawings and building sections. By accurately defining the limits of a building envelope, many of the complexities in creating an accurate interior floor plan are resolved. Other deliverables can include elevations of interior spaces and reflected ceiling plans.
