27. § UAV’s are a powerful tool when combined with the new
features in Civil 3D and the new tool, Recap.
§ UAV’s offer value in many industries
Summary of Findings

28. § UAV’s are going to be part of everyone’s tool box
§ UAV’s offer value in a lot of ways (rapid deployment,
accessibility, time, low cost).
Summary of Findings

29. UAV Requirements and Recommendations

30. Regulatory Compliance

31. § UAV and Aviation Experience
§ Workflow Knowledge
§ Regulatory Compliance
§ Systems Integration
§ Safety and Risk Management
Program Management

32. Data Systems and Analysis
Processing
Archival
Storage
Transfer
Security

33. Application Development

34. § Risk tolerances are different between organizations
§ Biggest problem is that companies are not aware of the
risks they are taking.
Risk Management

35. Conclusion

36. § UAS create value
§ Stockpiles are one area where we see immediate
application
§ The results are better, faster, safer, less costly
Summary

37. Session Feedback
§ Via the Survey Stations, email or mobile device
§ AU 2015 passes given out each day!
§ Best to do it right after the session
§ Instructors see results in real-time
