Land Surveying & LiDAR Scanning
Conventional GPS / Optical Survey
Ground-collected data points by field crews
Use of high accuracy GPS receivers, optical total stations, and laser leveling
Obtains minimal data to achieve accuracy needs
Every ground point, utility, road, and other structure is collected and stored in a CAD format
Field staff with safety training for road and railway work
Collects 2 to 10 acres a day on moderately developed areas
Photogrammetrical Survey & Mapping
Unmanned Aerial Vehicle (UAV) mounted camera
Uses geo-referenced photos to create mapping
Supplemented by a few ground-collected points
Obtains several hundred high resolution photos
Used to create aerial image, CAD, and point cloud
No ground crew safety and access concerns on busy roadways and other hazardous areas
Collects 100s of acres a day limited by airspace restrictions and drone battery life
LiDAR Survey & Mapping
Uses multiple pulsed lasers to measure distances
Supplemented by ground collected points
UAV-mounted laser sensor with a navigation system (IMU)
Obtains about 40 points per foot depending on altitude
Used to create point clouds and CAD deliverables
No ground crew safety and access concerns on busy roadways and other hazardous areas
Collects hundreds of acres a day limited by airspace, altitude, and battery life on heavier sensor
Our survey team’s goal is to develop the highest quality survey to meet the needs of our client in the shortest amount of time. We use cutting-edge technology and expertly-trained personnel to deliver efficient, reliable survey data.
In additional to our team’s professional land surveyors, CAD technicians, and LiDAR professionals, our diversified staff includes certified right-of-way agents, GIS professionals, and professional civil engineers. We use the latest software technologies to ensure accuracy and reduce office time on our survey field to finish process.
Our expertise includes topographic surveying for hydrology, design, and construction; LiDAR scanning and photogrammetry; right-of-way and construction staking; as-built, QA/QC, and quantity determination . Our field crews are trained in detailed data collection, and utilize a fully-customized field code library. Coordination with data processors and CAD technicians facilitates project needs.
