Drone Roof Surveys and Aerial Inspections

Roof surveys and building inspections using unmanned aerial vehicles (UAVs or 'drones') have become a more efficient data collection process for many building and construction projects, compared to traditional ground-based methods. Major cost savings and speed of collection are the main reasons why an increasing number of companies are using drone mapping software. Drone Photography Services, based in Cornwall, UK, uses various DJI drones with zoom cameras and the latest software to deliver efficient, high-quality surveying and mapping data. Drones are not practical in all surveying applications, but the company has recently done surveys of a church roof and structure... (read more)

Using Drones in Construction for Aerial Inspection, Photogrammetry or Lidar

Drones are creating new workflows, processes and applications in construction design, surveying and mapping, and many see them as the future of the construction industry. Rick Rayhel, Microdrones' sales manager for United States' Western Region, is one of those people; he's seen first hand how drones can enhance the construction business. In the U.S., drones have only been used to aid construction in the last couple of years. On the precipice of drone potential, Rayhel said, “There’s never a lack of ideas or interest on what can be done with drones.” Perhaps the biggest advantage of drones in construction, though,...

Bridging the Gap between Aerial Imaging and Terrestrial Data Capture

The Challenges of Drone Use in Facade Mapping
There have been rapid advancements in unmanned aerial systems over recent years, yet there is widespread consensus that we have still only seen a fraction of how unmanned aerial vehicles (UAVs or ‘drones’) could ultimately improve efficiency for geospatial professionals and their customers. To get a glimpse of the future, 'GIM International' spoke to Mark Nicolai, co-founder of industry start-up Aeroscan. Here, he shares his vision of how drones could form the missing link between aerial imaging and terrestrial data capture. According to independent research by the likes of PwC and Goldman Sachs, the construction industry tops the list in... (read more)

Ordnance Survey Demonstrates BIM Potential with Pioneering Project in Singapore

By combining building information modelling (BIM) with geospatial technologies, Ordnance Survey (OS) is breaking down barriers in Singapore. OS has spent two years in the Southeast-Asian nation championing the use of BIM data and its potential to transform urban planning. Britain’s mapping agency lent its expertise to a project with the University of Singapore and the Singaporean government that aims to make Singapore a world leader in smart technology. OS’s role was to develop data processing and 3D data modelling to help Singapore plan its future city more effectively. It contributed knowledge about the CityGML data model, an exchange compatible with... (read more)

3D Modelling for Construction

When it comes to 3D modelling for construction, what are the advantages and disadvantages of photogrammetry versus Lidar in terms of accuracy, complexity and cost? Breaking away from laser measurement in construction is a taboo subject, perhaps hampering the use of photogrammetry. In construction, aerial survey has enormous time-saving benefits for measuring groundwork areas. Data can be used for asset classification, construction validation as well as health and safety. In particular, regular scans provide a time series of work in progress to detect new issues, managing risk rather than responding to it. This article looks at the state of the... (read more)

5 Ways a Drone Can Benefit Your Construction Company

The presence of drones for aerial mapping on construction sites is steadily growing. This is mostly due to the benefits of drones and how they help ensure construction projects go according to plan. Traditional construction site mapping methods are steeped in guess work and uncertainty. Making the right decisions during a construction project is vital to its success – aerial mapping can help you make the best decision based on up to date and accurate data. Here are the five ways your construction company can use drone mapping to optimize construction projects and make the right decisions. Up-to-date aerial data... (read more)

Taking Full Advantage of the Benefits of UAS Technology

Leveraging UAS technology across surveying and engineering sectors is demanding. Meeting the expectations of accuracy and accountability requires the best in expertise, methodology and equipment. The latest unmanned aerial system (UAS) photogrammetric hardware and software now enables surveyors to capture millions of survey measurements on the ground, where they would previously have measured only hundreds. It is essential to have the best-quality equipment, software and workflows to ensure this data is accurate, robust and defensible for professional use. Geosyntec is a leading consulting and engineering firm that works with private and public sector clients to address new ventures and complex... (read more)

Accuracy Near, Far, Above or Under – How is FIG Working Week 2020 Contributing

The skills that engineering surveyors had to acquire in order to respond to the challenges of the construction world have made them capable, also, of fulfilling other challenges, several of which motivated by an awareness of the limitations of our planet. Engineering surveyors have learned that they need to push the equipment and techniques to its limits, while having recognized the necessity to integrate new techniques which can present more complete answers, without forgetting an important qualifier: accuracy. The instruments and methodologies have allowed for the surveying engineers to start working either very closely to the studied object, or, otherwise,... (read more)

Rebuild Ready: 3D Mapping a Quake-damaged Cathedral

Surveying a damaged building can be dangerous. Mapping using drones reduces risk to staff and costs to the community. This case study on the iconic cathedral of Christchurch, New Zealand, severely hit by an earthquake, demonstrates how drones and advanced photogrammetry software delivered the orthomosaic map enabling the accurate spatial planning needed in order to rebuild the cathedral. In February 2011, New Zealand’s second-most populous city was rocked by an earthquake. The iconic Christchurch Cathedral was shattered in the shake, and the clean-up is still ongoing. Christchurch's central city and eastern suburbs were badly affected. Before the cathedral can be rebuilt and the... (read more)
