Drone Services
Cornerstone Earth Group incorporates the latest drone aerial imagery technology to manage your project safely and efficiently, from pre-development planning through completion. This capability is especially helpful during the geotechnical investigation and environmental site assessment phases. Utilizing our drone capabilities, we can quickly give you a comprehensive 360 degree view of your site, revealing potential impacts and concerns that may otherwise be overlooked, saving you time and money, all while reducing exposure to risk. Up to date geospatial orthomosaic map and imagery can also be used to chronologically document and provide accurate site progress report through construction.
Before, during, and after construction, our drone footage will give you invaluable access to detailed, accurate, and high resolution images of your project from every angle.
