Business Value

Business Value

01

The full 14.2 km corridor was mapped in two flight days instead of an estimated three weeks of ground traverse.

No lane closures were needed, and no crew had to work roadside in live traffic.

03

GIS-ready parcel boundary layers resolved the encroachment dispute ahead of the permitting hearing, keeping the project on schedule.
