ARC Aerial Imaging - UAV Operating and Service Safety

With safety always paramount and which forms as a key driver towards its professional UAV/drone aerial imaging procedures and services, ARC Aerial Imaging attended several nationally-recognised safety accreditation courses to give assurances to current and future clients of its operational and service safety.

Having already its own company health & safety policies in place and further enhanced (including UAV/drone, on site and personnel operating procedures), ARC Aerial Imaging attended the IOSH Working Safely course which, focused on best practice, is intended to improve its company-wide safety awareness culture and appreciation for safety measures.  Also recognised by CSCS as an equivalent to a Level 1 Award in Health and Safety in a Construction Environment, ARC Aerial Imaging will be undertaking the CSCS Exam in due course to also enhance its reputation within the construction services supply chain network.

Furthermore, ARC Aerial Imaging attended a 2-day ECITB CCNSG Site Safety Passport course which is aimed with an underpinning knowledge of Health and Safety to enable contractors to work on a site more safely with lower risk to themselves and others whilst meeting statutory requirements of the UK Health & Safety Executive.

Aerial Surveying Imaging Collection Accuracy Statements

ARC Aerial Imaging can safely, precisely and accurately plan to collect ~2cm GSD baseline geotagged aerial imagery and produce various geospatial products including orthomosiacs/landmaps, GeoTIFFs, 3D Google Earth layers and digital terrain and surface models. Furthermore, our services can also include providing geospatial analysis with informed consultation.

Our georeferenced products come with an accompanying Collection Accuracy Statement in the form of an Overlap Report image that is also generated during processing.  This indicates to the client and GIS end user on how many nadir images (indicated as black dots in the left Overlap Report image) contain a view of tasked survey location within the processed survey area and giving them an illustrative and informative representation on how accurate the aerial survey was conducted.

Generally, the more "looks" at a feature on the ground the system has to work with, the better the outputs will be (within reason).  The Overlap Report colour codes these numbers to inform the client when the system considers to be good or bad overlap coverage and helps them visualise the things that affect the collection of consistent overlap.

For example 1, 2, 3, 4 or 5 views (colour coded in reds) of an area is considered to be inadequate for the purposes of reconstructing a 3D scene.  6, 7 or 8 views (colour coded in greens) are considered adequate for the reconstruction of fairly simple features like fields, basic structures or stockpiles.  For the greatest ability to reconstruct a complex scene, getting 9 or more views (colour coded in blues) is required to have the detail necessary to reconstruct complex features like buildings, trees or other vegetation.

Hiring a Qualified and Certified UAV/Drone Aerial Imaging Company

If you are considering hiring a company that undertakes both stills and HD video aerial imaging through the use of UAVs/Drones for your business needs, it is VERY IMPORTANT that they ARE CERTIFIED to do so.  Only Civil Aviation Authority (CAA) approved entities are safe, qualified and permitted to undertake aerial imaging work in UK airspace.

BACKGROUND

To operate and deliver aerial imaging services using unmanned aerial vehicles, the operator/company needs to have what's known as a "Permission for Aerial Work" (PFAW) from the CAA which is a LEGAL requirement to possess when operating UAVs/Drones on a commercial basis in the UK.  Those that are NOT CERTIFIED yet have declared to clients they are "operating" commercially can POTENTIALLY BE PROSECUTED.  Those who employ the services of non-qualified providers could also be liable for prosecution.

In order to obtain PFAW, this is achieved by several staged processes.  Initially this is by undertaking appropriate theory and practical training from a CAA-recognised National Qualified Entity provider of training (Ground School); secondly, have been flight assessed on whatever platform(s) the operator/company intends to use to deliver their services; thirdly, compile key documentation (Operations Manual) before having it submitted to the CAA when complete.  Finally, and upon approval from the CAA and once the operator/company has received their PFAW, they are then permitted to operate UAVs/Drones on a commercial basis.

SUMMARY

Legitimate UAV/Drone aerial imaging operators and companies will always have a PFAW and should present evidence of this, accompanied with other key and pertinent documentation, upon request from the client.
