News & Highlights

aerial photography and video Aerial Photography and Video Services - Weston & Sampson utilizes its own commercially permitted and insured drone, operated by our FAA licensed pilot, to provide clients with aerial photography and video services at project sites.
restoration of historical documents Restoration of Historic Documents - Weston & Sampson performed a project that required historical existing documents to be scanned and indexed to CD\DVD for archiving. The almost 100 year old rolled historical plans (up to 42 inches by 27 feet) were carefully placed between clear sheets of plastic to protect them from damage during the scanning process. The scanned images were then geo-referenced, tiled, and re-printed into a more manageable a 42 inch by 36 inch map book.
