Manual inspection and maintenance of development and infrastructure projects that span over large tracts of land involve significant manpower and cost. Drones cuts these costs significantly by performing Unmanned Aerial Inspections/maintenance checks. Projects like renewable energy, transmission lines, oil & gas explorations and pipelines, cooling towers, train lines etc. can benefit hugely with this service. Crucial measurements like distances, areas and volumes can be made in sites with material and stocks that need to be checked/moved.
