GeoDigital’s Transmission Corridor Observation & Reporting (TCOR) system is a unique, cost-effective approach to assuring regulatory compliance.  A real time LiDAR system, TCOR offers rapid reporting and engineering quality data when required. 

The TCOR™ system utilizes regularly scheduled helicopter missions to acquire airborne inspection data, permitting detailed mapping, database updates, and analysis of infrastructure suited for viewing on a desktop PC or via our unique web mapping service.

GeoDigital's TCOR™ system works by using the latest technology to gather field data during regularly scheduled inspection flights. High resolution digital imagers and other sensors acquire continuous coverage of the right-of-way, providing updated geo-referenced datasets from every flight. Once processed and compared to previous data, our fast automated change detection software highlights areas of concern for more detailed analysis, providing our clients with the most recent dataset and maintaining the currency of their in-house GIS or our online service.
