GeoAccess Products

Aerial mapping can quickly and efficiently provide a means to assess the health and condition of a wide range of vegetation types and identify invasive species. The maps are a powerful tool for agronomists, farmers, growers and vegetation management teams to locate areas of concern quickly and allow ground-truthing to determine the problems and remedy the situation in much quicker time and make significant cost-savings.

Visible-spectrum images captured by the drone can be used to produce plant health maps using the Visible Atmospheric Resistant Index (VARI). Used in conjunction with a high-resolution ortho-mosaic this enables a snapshot of the health and condition of a wide range of vegetation types to be obtained in relatively short time. Plant health maps can be exported as several file formats, including shapefile (.shp) for use in agricultural software; GeoTIFF for GIS and JPEG for general viewing, for use in:

Agriculture

Forestry & woodland management

Site investigation – surface and shallow contamination affecting plant health (phytotoxic metals and substances)

Identification, localisation, control and eradication of invasive species

GeoAccess are currently working in partnership with Kraven Enterprises at to provide aerial detection and ground management of invasive plant species, including Japanese Knotweed, Giant Hogweed and Himalayan Balsam.

Our Principal Pilot has successfully completed a dedicated drone mapping course given by an ex-Royal Air Force aerial imaging and spatial analyst with 25 years of knowledge and experience in this highly specialist field. We can offer 2D mapping (ortho-mosaics) at various levels of resolution, with high relative accuracy and export the finished products in a variety of formats, depending upon client requirements. 3D models can be viewed in Sketch Fab and embedded directly in a webpage.

Point clouds can be created from the 3D models and exported as LAS files for use in CAD software.

Applications of ortho-mosaics:

Applications of ortho-mosaics:

An overview of large roof areas for commercial, industrial and retail premises to aid in inspections

Reconnaissance of land for site investigation: access points, limited clearance, traffic routes, compound and laydown area selection, waste/fly-tipping, areas of surface contamination, poorly drained ground

Pre-construction/site set-up stage: access points, limited clearance, traffic routes, locating site offices and parking areas

Construction: site layout planning, documenting construction progress, materials and waste storage area selection and monitoring, identifying on-site issues such as traffic route degradation, housekeeping, drainage problems

Demolition: planning and visualisation, access, progress monitoring, recyclable and non-recyclable waste segregation and stockpiling

Relative measurements of length, area and volume

Applications of 3D models:

Earthwork, slope and rock face failures: determine causes and mechanisms involved; planning of repair/remedial works

GeoAccess utilises Pole Star Infrastructure Asset Management software in all our operations. Pole Star systems currently provide key solutions to Network Rail, Highways for England, the renewable energy sector, ADIPS (theme park inspections), the petroleum industry and utility companies. 

Pole Star is a GIS asset management solution enabling us to:

Pole Star is a GIS asset management solution enabling us to:

- Plan, programme and schedule work

- Undertake desk studies and pre-site surveys

- Send and receive live data between site and office

- Capture data in the field which is geo-tagged and site-specific

- Generate reports from the field and the office

- Undertake a detailed analysis of data captured

- Share data with clients

- Plug data into client’s asset management systems

Once the preserve of traditional remotely operated vehicles (ROVs), GeoAccess can now offer underwater inspections, photography and video with our submersible drone, the Chasing-Innovation Gladius V2. We strongly believe that we can offer a cost-effective, comprehensive underwater inspection service, providing high-resolution photography and 4K video, without compromising quality and safety, and without having to rely on larger, cumbersome, less manoeuvrable ROVs.

The Gladius V2 can be operated in freshwater and saltwater environments. It is rapidly deployable from shore or boat and requires a crew of two to operate (pilot and technician). The Gladius is attached to a 100m tether with a towable wi-fi buoy to extend the operating range if required. It can operate at depths up to 100m, has an endurance of up to 4.5 hours with rapid recharge times of both drone and wi-fi buoy in less than 2 hours. Following several successful test-dives on the Isle of Wight during August 2018, we are now ready to go operational.

There are numerous applications for a submersible drone, including:

Inspections of masonry/concrete dam walls; spillways; quay walls; sheet-pile walls; lock gates; scour protection; embankments; earth-fill dams; intakes & debris screens

Confined spaces: service reservoirs; water tanks; pipelines; flooded tunnels and shafts

Below the waterline foundations for the effects of scour

Underwater archaeology: photography; video; survey

Aquaculture (fish and shellfish farms): monitoring health of stock (disease, fatalities); stocking densities; condition of cages/nets

Dive site survey and reconnaissance either operating independently or in conjunction with human divers for hazard identification and risk assessment

Supporting human dive teams: safety overwatch

Assist in search and recovery of persons and objects

GeoAccess are always ready to embrace new technology and innovative designs, to that end we have recently acquired a collision-resistant cage for our DJI Phantom 4 Pro by DRONECAGE to enable us to safely conduct inspections in locations that are difficult to access, and certain types of confined spaces.

The DRONECAGE provides an additional layer of safety and significantly reduces the risk of damage to the subject being inspected and the drone. Inspections at height can be conducted without the need to shut-down activity at ground level or clear personnel from the surrounding area. The 20-megapixel camera of the Phantom 4 Pro produces super-sharp, high-resolution images that can be enlarged significantly without suffering pixelation and shoot HD and 4K video. Two 1500 lumen, adjustable brightness light sources can be mounted on the cage to provide light in poorly illuminated areas. The caged drone can be used for:

Inspecting interior structural steelwork, particularly roof and canopy support

Inspection of pipework, valves, conduits and cables at height and in restricted access areas

Inspections of silos and tanks

Bridge, tunnel, shaft and culvert inspections

Performing safety checks in deep excavations, underground mining and tunnelling operations

Interior inspections of derelict and dilapidated buildings prior to demolition or remedial works to ensure personnel can enter safely

GeoAccess can offer a stand-alone UAV inspection service and also integrated UAV plus rope-access teams, depending upon the requirements of the inspection. Our flight-crews and rope-access technicians are from similar professional backgrounds, have shared knowledge and experience that allows them to work together seamlessly and efficiently.

Our primary inspection UAV is the DJI Matrice 210RTK, equipped with Zenmuse Z30 camera that has x30 optical zoom and can be mounted on a downward or upward looking gimbal. The 210RTK is a rugged, dependable industrial-grade UAV with an IP43 rating we can operate in less than ideal weather conditions. The Z30 camera allows inspections of assets in medium to high-risk environments from a safe distance and the RTK GPS units allow precise flying and positioning when in the hover, as well as being resistant to electromagnetic interference.

Key advantages of using UAVs:

Rapid deployment

Safer working with a significant reduction of risk

Initial and detailed inspections can be undertaken

Urgent defects can be quickly identified and reported

Areas requiring tactile inspections and non-destructive testing are identified at an early stage

Identification of specific locations requiring rope-access inspection teams

Site risk assessment prior to deployment of rope-access teams

Integrated UAV and rope-access:

Improved utilisation of rope access teams

Teams can focus on specific locations identified by UAV

Efficient planning and execution of tactile examinations and non-destructive testing

Safer working and reduction of risk using UAV to provide a safety overwatch and monitor rope teams at work
