Why LiDAR Technology?
Repeatable, accurate, and dependable technology
Cost effective for system/large circuits
Technology very good at collecting and measuring transmission features: structures, insulators, attachment points, vegetation, and ground

PRE0101 10
Typical LiDAR densities for electric power line collection range from 20-30+ points per square meter
In general, the more density the better for feature collection, definition, and extraction

Workflow
Begin with centerline file and bare earth points to seed the process
Test filter settings in localized area. Once optimized…
Line / facilities detection filter over larger region
QA / QC windows are launched for manual clean-up
Attachment points are classified
For the point cloud classification of transmission facilities and QA / QC of classification results.

MARS® Power Line QC report - Report on LAS Statistics (by Tile)
Black line items: Points exist on a required class. We expect to have points on this class.
Teal line items: Points do not exist on a required class. This flags a potential issue. Classification of the transmission facilities is incomplete.
Red line items: Points exist on a non-required class.Another potential issue. This may be okay for outlier or erroneous points.

Begin with a calibrated camera model
Create an exterior orientation file with position and attitude for each image exposure station
Project the image footprint on to a surface Surface must be in same coordinate
system / units as LiDAR bare earth
In Optimum Image Selection Tool Image with shortest slant-range to given
horizontal coordinate (E, N) is selected
Image ID is either written to point shapefile attribute table or called up in viewer window
