Photogrammetry with Drones and its advantages for Urban and Rural Digital Restitution

representacion digital de terreno obtenida mediante la tecnica de la fotogrametria con drones

One of the most requested technologies from Acero Estudio is photogrammetry with drones, a set of methods, software and hardware (with drones) that is not only changing the way civil projects are executed but also speeds up and achieves greater efficiency in construction projects. digital restitution in urban and rural areas.

The representations achieved through photogrammetry enable the creation of accurate digital representations while enabling a number of key benefits for project planning and development in these diversified environments.

Creating accurate 3D models

Drone photogrammetry offered by Acero Estudio, a company specialized in photogrammetry and BIM, stands out for its ability to generate precise and detailed three-dimensional models of urban and rural areas. This is achieved by capturing multiple aerial images from different angles and altitudes, which are then processed to create a digital model of the terrain. This digital model, often known as an orthophoto or mosaic, serves to achieve a faithful digital representation of the area in question.

Practical Case

A municipality needs to update its urban plan to allow for sustainable growth. Thanks to photogrammetry, an accurate digital representation of the city can be created, including buildings, streets, vegetation and bodies of water. This digital representation will serve as a basis for future analysis and planning.

Efficient Planning

The availability of accurate digital representations is very useful for effective planning in urban and rural environments. Data generated through drone photogrammetry allows planners and designers to make informed decisions about infrastructure siting, natural resource management, and land use planning. This significantly reduces the margin of error, minimizing risks associated with any large project.

Practical Case

In a region prone to flooding, photogrammetry is used to generate various digital representations that are very useful to identify flood-prone areas, allowing corrective and protective measures to be taken in the surrounding areas.

Change Analysis

Drone photogrammetry allows for monitoring changes over time. This is especially valuable in constantly evolving urban and rural environments. Drones can perform regular inspections to capture updated images and detect significant changes to the landscape or infrastructure.

Practical case

A municipality seeks to evaluate the impact of an urban development project and for this drone photogrammetry can be used to track the evolution of the area over several years. This allows them to make data-driven decisions and adjust their planning as necessary.

Access to Remote Areas

In difficult-to-access rural areas, drone photogrammetry becomes an invaluable tool. Drones can reach remote and hard-to-reach places, allowing data capture in mountainous areas, dense forests or rugged terrain. This expands the possibilities of collecting accurate information in environments that were previously inaccessible or expensive to study.

Practical Case

In the preservation of remote natural areas, drones can be used to monitor the health of the ecosystem and detect signs of deforestation or erosion in places that are difficult to access or at risk for people.

Drones, transversal tools beyond the AEC sector

drone applications

The technological advances of drones make their use multidisciplinary.

Today, its integrated technology has allowed the capture of valuable data through images, videos, thermal information and other data, but today its applications are completely transversal, also allowing the possibility of offering other services, ranging from generating statistical information in time real to being vehicles capable of spraying chemicals on crop fields.

Drones are becoming more accessible every day, however their capacity and applications are progressively increasing. Despite the possible limitations of these tools, it is imminent that carrying out tasks with the use of conventional methods can be expensive, dangerous and sometimes simply impossible when it comes to accessing complex areas in services such as construction monitoring or photogrammetry with drones.

There are sectors where drones have a greater impact, but their presence is increasing in all sectors. Below we detail some of those applications.

Acero Estudio is passionate about innovation. Our team is prepared for great challenges. Finding the “how to do it better” is always our goal, based on curiosity and experience we look for efficient solutions and seek to optimize resources when approaching a project.

The indispensable help of drones

topografia y drones

Drone technology is advancing at exponential rates and is increasingly accessible, which is why different sectors are taking advantage of and adopting drones in their work to drastically increase their efficiency. In other words, drones are changing the way businesses operate by reducing costs, saving time, improving safety and providing a direct return on investment, so their impact should not be ignored.

In particular, the use of drones in topography (topographic surveys with drones) represents a revolution. While the use of traditional methods provides more precision, the use of drones in this type of work offers more survey surface in the same period of time.

“There is a saying in the construction industry: “Time, cost and safety, pick two.” And what makes drones really transformative for us is that we can choose and improve all three.”

– Grant Hagen, Director of VDC, the Beck Group

As we already know, the use of drones brings with it a large number of advantages and each of these advantages has to do with their ability to reduce the time, danger and cost of the project. However, another very important factor to consider is this, are drones as accurate as traditional ground surveying methods?

For many years, the precision of drones has not lived up to their theoretical potential although this has begun to change. With drone solutions, a wide selection of surveying techniques is available that allows any project to be developed with excellent results.

At Acero Estudio, a company specialized in drones for topography, LIDAR and photogrammetry, we invested in drones for the development of this type of projects and we were not wrong. What are you waiting for to find out?

Drones and their transformation of the AEC industry

drone inspección de obras

Companies in the AEC (Architecture, Engineering, Construction) industry are using drones to quickly and accurately collect topographic data.

The architecture, engineering and construction sector has historically been slow to adapt to technology. In fact, according to a report by the McKinsey Global Institute, the construction sector is one of the least digitalized. This is underlined by another report, this one from JBKnowledge, which reveals that almost 60% of construction companies do not invest in new technologies.

Much of the AEC industry is using technologies and processes that no longer adequately serve their needs, either for projects or for associations. However, one area where the construction industry is expanding its use of emerging technology is the use of drones. Estimates by PricewaterhouseCoopers place sources of drone work for infrastructure at a market value of $45.2 billion. Today, an increasing number of disciplines within construction projects – such as designers, surveying companies, environmental consultants, builders and inspectors – use drones in the field to take aerial photography (drone photogrammetry). , volumetric analysis and topographic mapping, among many other things.

The ability of drones to collect real-time data on the jobsite has dramatically increased workflow and efficiency in design and construction. Drones are used most frequently in construction to carry out studies on construction sites, as is the case of our company, Acero Estudio, supervising the progress of the GECAMA wind farm in Cuenca, with the help of this technology. . Drones capture data that surveyors need but typically cannot see, as they have an unobstructed, high-altitude view of the construction site.

This also helps make the construction site safer, as drones can inspect difficult or dangerous terrain, keeping human surveyors out of harm’s way and helping construction workers avoid dangerous areas. For all these reasons, drones are replacing traditional methods of terrain surveillance and greatly reducing the time and manual work required.

It is an irony that the AEC sector is one of the slowest to adopt new technologies and yet one of those that could benefit the most from them. However, this sector has more readily adopted the use of drones, which can save large design and construction projects a lot of time and money.

estudio conceptual para restitucion accesibilidad metropolitano de lima

The Acero Estudio team in Peru carried out the geodesy work, drone flight and restitution of the area planned for Pedestrian Accessibility to and from the Metropolitan Stations, Lima.

Given the current global pandemic situation due to COVID-19, these tasks were all carried out under preventive measures and medical examinations.

To better understand the work carried out by our team in the project area, they began with the placement of Geodetic Points (one at each station) linked to the IGN coordinate system. Their measurement using dual-frequency differential GPS. Next, the necessary support points were located for the subsequent restoration of the drone flight. These support points were marked with an X-shaped template and paint, and measured with GPS in RTK mode.

The drone flight of the 33 stations was carried out at an appropriate height taking into account the height of the existing buildings and elements. For this, a DJI Phantom 4 Pro drone with a 20 Mpx camera was used. Once the photogrammetric images were obtained, they were processed and the point cloud and orthophoto of each station was created. With the orthophoto and the point cloud, the MDT was processed and subsequently the restitution of the environment of each station.

We thank our client CPS for all the trust placed in our team and the work of coordinating and directing the work carried out.
