Surveying and Drones Services

SHN blends traditional and new technologies for accurate and efficient surveys.

SHN has provided land surveying services for over 40 years and we are adapting new technologies to improve efficiency while maintaining industry standards for accuracy.  In a quickly evolving profession, SHN land surveyors, drone pilots, and information technology staff are creating new workflows of mapping, data collection, measurement, and visualization using drones and supporting data management systems. 

SHN’s Unoccupied Aerial System (UAS or “drones”) program is different because our licensed pilots are professionally licensed surveyors and geologists.  We combine our expertise in mitigation monitoring, restoration planning, and large-scale earth and materials movement with drones and traditional surveying techniques.  We use aerial imagery and video to engage the public and better describe projects. 

Traditional land surveying services continue to be in demand.  Our surveying experience covers a range of land uses, including residential, commercial, and industrial development; urban and rural roads, streets, and bridges; highways; subdivisions; water and wastewater treatment facility sites; private and public forest lands; public and private landfills; and wetlands, estuaries, and bays and rivers.

SHN is using a new scanning technology to generate “digital twin” images, which can be used to assign information to elements in the twin image, such as a clarifier’s pump model, installation and maintenance dates.
