Reconstructing the past
After a homeowner raised his house in order to put a basement under it, the house was set back down but not returned to its original elevation. The next-door neighbor complained, indicating among other things that the house’s change in height seriously compromised his privacy. His estimation of how much the house was raised significantly differed from the homeowner’s.
The investigation sought to determine just how much the height of the house had changed. This was complicated by very poor documentation of the position of the house before the new construction. A combination of surveying and a form of photographic analysis called photogrammetry helped to conclusively determine how much the height of the house had changed. These results helped to settle the dispute between neighbors.
