Terrapoint
Electric Transmission
Terrapoint provides transmission structure location, conductor catenaries and right of way data acquisition using LiDAR, geo-referenced digital still imaging and digital video for inspection problems and population of transmission GIS.
LiDAR combined with imaged data can be used for the following corridor mapping applications: calculating power line heights, or sag under different loads, inventory, tower placement and height of underlying vegetation, and danger tree identification.
Alternatively, the ground-based TITAN® system can be used to capture less substantial cabling such as that found in residential areas, for population of residential GIS. Hydro utilities are now using LiDAR data operationally for line re-rating, tower/line re-engineering and new line site selection.
Deliverable Formats
LiDAR data is acquired, processed and delivered in digital format. This makes it very easy to create data products that meet a wide range of needs. Programs such as AutoCad, ArcView and PLS-CADD have the capability to import and export LiDAR data. Terrapoint also offers GIS training and consultations to assist companies integrate LiDAR data and solutions into their internal operations.
