Ultra high-resolution aerial ortho-imagery, highly accurate digital topographic surveys, gas mapping and advanced spatial analysis supply the foundation for a comprehensive suite of information services which directly benefit pipeline monitoring, inspection and management. Ventus Geospatial leverages the latest in geomatics and Unmanned Aerial System (UAS) technology and geomatics expertise to acquire seamless high-resolution aerial imagery, topographic information and gas concentrations over pipeline right-of-way. This unique capability enables data acquisition, processing and analysis to provide cost-effective, comprehensive solutions when compared to more costly, manned aircraft systems or helicopter flights.
- Ultra High-resolution Imagery
- Corridor Encroachment Mapping
- Subsidence Depth Mapping
- Unmanned Aerial Gas Mapping / Gas Plume Modelling
- Depth of Pipeline Cover
Ventus Geospatial is a world leader in the successful development of the first unmanned aerial gas detection system. The gas detection system utilizes the latest in Unmanned Aerial Systems (UAS) technology equipped with cutting-edge laser mass spectrometer to effectively detect gasses down to 1 ppm. This highly advanced gas detection system is backed by powerful analytics and software which has been researched and developed to account for atmospheric and meteorological conditions during flight planning to best detect potential leaks.Those leaks are then analysed by specialists to calculate the highest-likelihood location of an actual leak source based on advanced gas plume modelling. Natural gas pipeline leak detection, liquefied natural gas (LNG) production, storage, and transport, GHG monitoring and facility monitoring area ideal applications for this gas detection service.
- Carbon Dioxide (CO2)
- Methane (CH4)
The use of unmanned aerial systems (UAS) allows for the capture of detailed aerial imagery as well as georeferenced topographic data with absolute accuracy of 10 cm. UAS allow for a highly efficient data capture methodology to be employed, providing an all encompassing data set over the entire area of interest. Conventional seismic survey methodology is limited to the area a person can physically cover in the allotted time frame, this dramatically limits the completeness and accuracy of the hazard survey. UAS topographic data and aerial imagery also offer the ability to easily modify plot maps and snail trails with existing digital imagery and topographic data without the need to capture further field data or delaying seismic operations. Though the use of this advanced technology HSE exposure can be vastly reduced as the need for surveyors to be “working alone” in remote areas is removed and the efficiency to the UAS platforms allows work hour exposure to be reduced by up to 90%.
Ventus Geospatial leverages the latest in geomatics, Unmanned Aerial System (UAS) technology and expertise to acquire seamless topographic information and aerial imagery which serve a wide variety of engineering projects. Data acquisition is quick, comprehensive, accurate and highly detailed, making it ideal for engineering design, site selection and infrastructure development.
Ventus has the unique capability to extract engineering grade Digital Terrain Model (DTM) from Digital Surface Models (DSM) making it possible to have buildings, trees, vehicles, fences, vegetation and other ‘off-terrain’ surface features removed from elevation data to produce an engineering ready ‘bare-earth’ or ‘ground’ surface which are RTK referenced to under 5cm vertical and 3cm horizontal accuracy. With the use of the latest geomatics and surveying technology such as:
- Laser Scanning
- Total Station
- RTK GPS + UAS enables fast accurate data acquisition
- Processing and analysis for tailored solutions
Ventus Geospatial leverages the latest in Unmanned Aerial System (UAS) technology and expertise to acquire ultra high-resolution visual and thermal imagery which is ideal for inspecting facilities with increased safety.
Data acquisition is organized to obtain complete coverage of a facility, with high-resolution images from all angles so that every aspect of condition can be inspected. Thermal inspections provide insight into building thermal efficiency by measuring relative and absolute temperatures. Imagery acquired during an inspection are compiled into reports which detail areas of concern or interest to support proper management practices and compliance.
