How do we use it

WTD DRONE

RPAS as Platform

Multi-rotors

Fixed-wing & VTOL

  • Shorter flight time (< 45 min)

  • Cover smaller area

  • Highly maneuverable

  • Less expensive

  • Access to confined spaces

  • Long flight time (+ 40min)

  • Covers very large area

(vertical take-off & land)

Companies are using maps not just as nice features but to drive revenue as core components of their offering. Maps are no longer just a good way to visualize content, they are core to competitive advantage.

Companies are thinking more creatively about how to combine location with outside content and internal business data to differentiate products
