What is LiDAR?
Light Detection and Ranging. The dictionary title: a measuring system that detects and locates objects on the same principle as radar but uses light from a laser. A method for quickly and accurately collecting ground information from an aerial platform using a laser and ground control. In the technical definition of the word, LiDAR is a survey but it cannot be used for a legal boundary survey. How is LiDAR Data Collected?
What Data is Collected During a Flight? “ Everything ”
- Foliage
- Bare Earth
- Transmission Lines and Towers
- Railway Beds
- Roadways
- Vehicles
- Buildings etc.
- Optional
- Photography
- Weather Conditions
What Were the Deliverables to VELCO?
- DTM – Digital Terrain Model
- Orthorectified Imagery
- AutoCAD Drawings
- Contours
- Streams
- Roads
- Buildings
- Utility Lines and Poles
- Edge of Trees
- PLS?
CADD Terrain Model PLS? CADD (Power Line Systems ? Computer Aided Design and Drafting): overhead power line design software.
What Has VELCO Created With the Data?
- New Transmission Line Designs
- Permitting Drawings
- EPSC (Erosion Prevention and Soil Containment)
- Plans
- Aesthetic Mitigation Plans
- Tree Planting etc.
Issues Encountered With the Data?
- Mobilization
- Ground Control
- Foliage
- Units Conversion
