LiDAR
LiDAR technology offers one of the most accurate, expedient and cost-effective ways to capture elevation information. LiDAR data is directly processed to produce detailed bare earth models in a variety of formats including LAS, ASCII, ESRI and CAD. Typical horizontal accuracies range between 20cm to 1.0m and vertical accuracies range between 0.924 to 18.5cm. Derived products include DEM, DTM, DSM, contours, slope/aspect, 3-D topographic images, virtual reality visualizations and planimetric detail.
Equipment & Capability
AeroMetric employs Optech's GEMINI enhanced accuracy systems. Many regard this as the best LiDAR equipment on the market. The new system will produce horizontal accuracies of 1/5500 of the altitude. Vertical accuracies of less than 5 cm are possible at 500 meters altitude, and less than 20 cm at 3000 meters.
Aerometric is staffed by some of the most seasoned LiDAR professionals in the industry. These specialists have extensive experience with all facets of LiDAR including applications development, sensor development, programming, survey, data processing, data acquistion, GPS and IMU process development and multi-sensor intregration.
Process
AeroMetric seamlessly integrates LiDAR data with other data sets, including orthophotos, multispectral, hyperspectral and panchromatic imagery. We can combine LiDAR with GIS data and other survey information to generate complex geomorphic-structure mapping products, advanced 3-D models/earthwork profiles, renderings of structures, and many additional high value mapping products.
Deliverables
LiDAR point clouds can be used to derive a wide variety of geospatial deliverables including:
- Intensity images
- Breaklines
- Digital Terrian Models
- Digital Elevation Models
- Digital Surface Models
- Triangular Irregular Networks
- Vegetation layer for analysis
- 3-D Models
