Job: To provide a detailed orthomosaic and digital terrain models for a new sub division.

Challenges: To provide a detailed orthomosaic and digital terrain models for a new sub division once the roads were installed and before construction of the properties began that was detailed enough to pick up the block title survey markers and could be regularly repeated on call when required on a regular basis.

Solution: Airsight Australia operated an advanced photogametry fixed wing UAS called the Avian-P. With 70 minutes flight time capability and ability to operate in rain and winds up to 45km/h, the Avian proved to be the most capable UAS system for the job.

Results: Within 48 hours of flying the mission, Airsight Australia was able to deliver in full the required deliverables, including dense and sparse point cloud, Digital Terrain Model (DTM), orthomosaic and 3D model. With a GSD of 3.8cm and a vertical accuracy of 7.7cm using 8 ground control points over an area of 0.45km2.

Job: To carry out photographic internal and external inspections of coal surge bins.

Challenges: To provide detailed photographic inspections of the internal and external coal surge bin structures in Newcastle. For the internal steel linings of the surge bin it was important to get hi-resolution images of the lining, and for the external the same was required, high detail still photographs of the external steel lining, structure and steel beams.

Solution: Airsight Australia designed an inspection plan using two of our advanced multi rotor UAS with live video downlink using two operators. Specific allowances during flight planning and operation were made for potential weather and personnel risks though a detailed Safe Work Method Statement and close communication with supervisors and managers.

Results: High resolution still photographs were captured providing highly detailed imaging of the entire surge bin structures, both internally and externally. The UAV was manoeuvred very close (<3m) to produce high resolution images of the entire steel structure.

Airsight Australia was able to complete the entire external inspections for four bins within 2 days while the internals of each bin took 3-4 hours each. The total project was completed in 7 days spread out over plant shut down times. Airsight Australia was able to reduce the overall cost of carrying out the inspection to one tenth of other traditional means of inspection.

Job: To carry out a complete roof inspection on Onesteel’s wire rope plant.

Challenges: To provide detailed photographic and video inspections for the 50,000m2 (approx) of tin and asbestos roofing for the Mayfield West Onesteel plant. Due to the asbestos roofing, having people walk on the roof carries a high level of risk.

Solution: Airsight Australia designed an inspection plan using our advanced multi rotor UAS  with live video downlink using 2 operators as well as an elevated work platform to maintain visual line of sight with the UAV. Allowances during flight planning were made for potential weather and personnel risks though a detailed Safe Work Method Statement.

Results: HD video and hi-resolution still photographs were captured providing detailed imaging of the entire roof line and guttering. Where roof damage was visible via the video monitors the UAV was manoeuvred very close (<3m) where further high resolution images were acquired to provide an extra level of decision making information.

The job was completed within 6 hours and data delivery was made within 9hours.
