EagleView® Technologies utilizes Pictometry® technology to deliver a cost-effective vegetation clearance management solution to utility companies and industry-leading engineering partners that satisfies technical objectives. High-resolution oblique and vertical images are captured along the transmission corridor and synchronized with a medium-density LiDAR point cloud. Since most utilities now have complete PLS-CADD models, a medium-density LiDAR solution coupled with metric oblique imagery provides the ideal balance of accurate data versus price.

Six steps to cost-effective vegetation management Pictometry’s PentaView Sensor System is comprised of custom-designed, fully calibrated photogrammetric lenses and a recently updated 29 megapixel CCD sensor. This latest configuration is specifically designed to support corridor mapping applications and produces, in a single pass, both LiDAR data and high-resolution imagery of unmatched clarity. The increased swath width coverage that comes from the use of fixed-wing aircraft presents a significant operational advantage over a rotary platform, lessening the financial impact to the customer.

1Data Collection High-resolution, metric imagery of the corridor captured at one- to two-inch GSD (equivalent to 400-1500 ppm*) in a single pass.

LiDAR captured with Riegl 680i unit and synced with the imagery for discrete vegetation modeling; collecting at approx. 6-7 ppm*.

2Data Processing LiDAR from the aircraft is processed and synced with the high-resolution ortho and oblique imagery.

3Co-registration New LiDAR point cloud is co-registered to the customer-supplied data (typically Method 1 or Stick Structure) and held as control. The new vegetation point cloud will be accurately referenced to the control.

4Data Validation and Verification Tower tops, cross arms and attachment points can be verified between the control and new LiDAR model with inconsistencies checked against the imagery. Unclassified LiDAR points can be verified through the use of synchronized imagery.

5Imagery Quality Assurance/Quality Control High-resolution metric oblique image is used to verify new structures, lines and attachment locations when conflicting information is found.

6Vegetation Clearance Report and Analysis Full clearance analysis is performed on the combined datasets and can be delivered through a standard Plan and Profile.

Processed imagery and LiDAR data can be delivered to the customer through EagleView’s CONNECT™ enterprise web-based software.
