We are frequently asked by our clients to evaluate the geotechnical aspects of existing and proposed developments at the desktop level prior to, or in addition to, conventional field and visual inspections.  We regularly use LiDAR (Light Detection and Ranging) data and other forms of geospatial mapping for multiple purposes, including:    

  • Evaluation of slope stability conditions and landslide identification.

  • Determination of expected surficial soil and drainage conditions.

  • Identifying areas of potential for erosion and sediment transport.

  • Geohazard assessments for linear corridor developments.


We use LiDAR data to create 3D terrain models to help illustrate the locations of various terrain features, and we often overlay survey data provided by our clients onto LiDAR imagery.  The result is a clearer view of the location of developments relative to potential geotechnical hazards such as landslides and erosion.

We work with aerial photography including imagery captured by our own UAV drones, as well as imagery provided by a locally based subcontractor who employs specialized helicopter-mounted camera and GPS systems.  We continually work with local survey companies and other mapping providers to best serve our clients' mapping needs.
