  • Emesent offers SLAM, lidar, RTK and 360° imagery mobile scanner

    Emesent offers SLAM, lidar, RTK and 360° imagery mobile scanner

    Emesent has launched its GX1 all-in-one mobile scanning system at Geo Week 2026 in Denver.

    The GX1 is an integrated, highly accurate all-in-one mobile scanning system combining simultaneous localization and mapping (SLAM), lidar, real-time kinematic (RTK) georeferencing, cameras and software. The product marks a breakthrough for the autonomous mapping technology company.

    The GX1 supports a seamless workflow, from capture to validated deliverable. It not only brings Emesent’s proven SLAM technology to everyday surveying applications, but also eliminates the longstanding trade-off faced by survey firms and players in the architecture, engineering and construction (AEC) industry between mobile scanning speed and dependable survey-grade accuracy.

    According to Emesent, the GX1 can reduce the time required to survey a site by up to 95%, reducing what once took weeks into a single day of scanning. Meanwhile, the independently validated global accuracy of 5-10 mm delivers the precision needed for use cases across topographic and road surveying, scan to building information models, construction progress tracking and more.

    These capabilities are supported by integrated RTK georeferencing with real-time quality monitoring, four 20MP cameras for 360° panoramic imagery, and Emesent’s proven SLAM algorithm. This technology — which also powers the Emesent Hovermap product — was developed and validated in extreme real-world environments, including GPS-denied, underground locations to ensure repeatable accuracy and reliability both indoors and out. Accuracy validation reports are produced quickly and easily in the Aura processing software.

    With four purpose-built deployment modes — backpack, survey pole, vehicle mount and supported handheld — and integrated batteries for cable-free management, the GX1 offers a high degree of versatility. In addition, surveyors can capture data using RTK in the field or using ground control points and checkpoints in post-processing. This flexible georeferencing minimizes the risk of having to return to a site for redo.

    “With the introduction of the GX1, we’ve answered the call we’ve heard echoing throughout the surveying industry to end the tug-of-war between fast and accurate,” said Dr Stefan Hrabar, chief strategy officer and co-founder of Emesent. “By putting the power of SLAM into the hands of the everyday surveyor, the GX1 raises the bar for mobile scanning accuracy and keeps critical projects on track.”

    The launch of the GX1 comes at a pivotal moment for survey firms and the AEC industry. They are grappling with a shortage of experienced surveyors, while also facing mounting pressure from clients demanding faster, cheaper and better results without compromising on quality. The GX1 has been designed to be simple enough for junior surveyors to train on and deploy in a matter of days. At the same time, it is powerful enough to meet — and, according to Emesent, exceed — the real-world needs of professionals in the field.

  • AEC firms use aerial mapping to share infrastructure funding

    Photo: Nearmap
    Photo: Nearmap

    With Congressional approval of $17 billion in infrastructure funding, the largest single allocation ever, the scramble to win contracts is about to get red hot and AEC firms are gearing up. In this very competitive game, top engineering firms are relying on their experience, technology, business acumen and ability to execute.

    Advances in aerial mapping play a key role in how AEC firms pursue these contracts. Savvy firms have been using this technology for years. Rather than rely on lower resolution satellite imagery or local drone imagery, they use wide-area-coverage aerial maps to clearly display the detail needed to plan and execute.

    Over the past decade, maps made using aerial photogrammetry have played an important role in the AEC space. Using high-performance cameras, fleets of planes capture hundreds of square miles per plane per day, provided that the weather is clear. The imagery is processed and made available to engineering companies within days of capture, allowing them to see very clear imagery.

    AEC organizations use different forms of aerial maps to evaluate sites, improve their survey designs, and build and maintain infrastructure (roads, highways, bridges, tunnels, overpasses, rail, airports, housing, commercial building development, water resources, parks, pavement and more). Imagine you’re a state or local government that needs to build a bridge, or a developer who wants to contract with an engineering and construction firm to build affordable housing. Why travel to perform time-consuming site evaluations when you can meet with engineering teams in your office and review hundreds of potential sites instantly using current aerial photos that show change over time?

    The engineering teams point out elevation changes, the presence and height of vegetation, neighboring communities, bodies of water, ponding and more. They easily navigate from one location to another as you discuss where the entrance to the community could be, how the road network might be configured, and the proximity to retail, schools and healthcare. Within minutes you measure risk, understand the landscape, make decisions, and begin to estimate the project costs. Your teams collaborate, discuss the pros and cons, measure distances and navigate across the terrain virtually.

    Aerial mapping provides a competitive advantage for AEC companies to win their fair share of the infrastructure bill. It also gives governments and developers the confidence they need to make the right decisions. Typically, this involves looking at sites from all angles. The classic form of aerial mapping used by engineers is a top-down perspective. Increasingly, these organizations have used oblique imagery captured at an angled perspective, which shows height.

    Artificial Intelligence and Aerial Photography

    Starting a few years ago, 3D imagery and digital surface models began to allow engineers to navigate through the imagery and query it based on elevation. More recently, aerial mapping has leveraged artificial intelligence (AI) to classify properties and the landscape. Do you need to see nearby construction sites? AI applied to aerial photography can do that automatically. This rich set of data includes attributes such as tree overhang, roof condition, roof material, building footprints, vegetation height, surface material, swimming pools and even solar panels.

    The blend of all these imagery types and AI into a single solution makes everything discoverable. Users can search by address, city, location or point of interest. They can visualize the imagery along with lat/long coordinates and quickly switch from top-down views to obliques to 3D. As they learn more about the landscape, they begin to turn on AI attributes, gaining deeper insights.

    Sometimes, the analyses go even further. Engineering organizations export the imagery to tools of their choice from such companies as Autodesk, Esri or Bentley Systems, use field-collected ground control points to ensure that it is survey grade, then use it as a base layer for their designs. They even create marketing presentations and video content to help them win the business. Current high-resolution aerial maps have become a cornerstone of how these organizations operate.

    This approach provides unique advantages for engineering firms. For example, they can combine geospatial and construction datasets in a common operating environment to reduce complexity, streamline communication, ensure that all stakeholders are up to date, and check their progress toward meeting contractual obligations.

    Planners have current, contextual designs and models to make accurate decisions about planning and development activities. They can view asset locations and conditions to facilitate maintenance and upgrades, leverage aerial maps inside other platforms to improve work orders and reduce field visits, and ensure regulatory compliance.

    Whether it’s improving highway safety, constructing ferry terminals, improving transportation systems, developing land or building a network of recreational trails, aerial imagery provides engineering and construction companies with a competitive advantage to win new business, improve client satisfaction and meet growth targets. With $17 billion on the line, sophisticated firms are finding a way to secure their fair share of the pie.

    While some tasks for AEC surveying are similar to other types of surveying — such as original ground surveying, creating site control and live monitoring — the biggest differences and challenges arise in data management, timeframes, communication and deliverables.

    In AEC surveying, the project timeline is the primary factor driving everything, creating a different kind of pressure on the surveyor. As data experts and problem solvers, surveyors for AEC must quickly adapt to construction progress, as their survey knowledge can be needed on site at any point.

    Information transfer challenges also exist — such as clearly communicating data to non-surveyors who perform measurement tasks — along with creating unique deliverables across construction stages. These include 3D terrain models with real-world coordinates for architects; fit-for-purpose computer-aided design and Industry Foundation Class models for machine operators and mechanical, electrical and plumbing installers or off-site fabricators; and progress reports for project owners.

    Several AEC firms have opted to create their own inhouse survey teams. This allows greater control over the consistency and clarity in communication and deliverables, because they focus exclusively on surveying for AEC and are therefore familiar with its specific challenges.

    The main challenge for the surveyor in AEC is sifting through and processing the data, assessing quality, understanding relevance, producing results and crafting deliverables to meet the clients’ needs.

    An integrated total solution is important for AEC surveyors who must decide not only which technology to use, but how to process data from different technologies together. Our products fit within this integrated solution concept.

    Leica Geosystems‘ automated total stations, multistations and GNSS blend innovation and traditional technology, such as the Leica GS18 I with tilt and visual positioning, enabling surveyors to measure more, faster.

    For mass data collection, the Leica RTC360 3D laser scanner operates at two million points per second and contains visual inertial system (VIS) technology simplifying the registration process. The Leica BLK series combines intelligence and accessibility, including the BLK360 imaging laser scanner, the handheld BLK2GO, and the latest autonomous technology of the BLK2FLY and BLKARC.

    Finally, our software connects surveyors to their sensors and data in the field with Leica Captivate and Leica Cyclone Field 360 and to the office with Leica Infinity and Leica Cyclone, extending to existing CAD software with the Leica CloudWorx suite of CAD plug-ins.

    Bringing an Aqua Park to Life

    One memorable success story was the use of our products for AEC survey tasks during construction of Germany’s biggest aqua park, Rulantica. The survey work was led by Saladin Keller of Keller planen + bauen. The project involved the creation and construction of a Nordic-themed water world featuring 25 attractions, including water slides, a wave pool and a lazy river.

    Alongside all the typical surveying for AEC tasks — establishing site control, staking out pipes, and planning and staking the entire traffic infrastructure — Keller had the challenge of measuring and positioning the complex internal geometry. These tasks required skilled surveyors and a variety of survey tools, such as total stations, GNSS rovers, laser scanners and powerful processing software.

    Operating within the AEC environment also meant that communication and flexibility were key to the success of the project. Keller needed to provide the right data to different trades and handle urgent maintenance requests requiring surveying skill, such as rebuilding parts and adjusting utilities.

    In this issue’s cover, a man with a backpack lidar unit, a GNSS receiver and a tablet computer is surveying in a complex and challenging urban setting. That same lidar unit also can be mounted on a UAV. One of the contributors to this month’s cover story describes the role of aerial photogrammetry in the architecture, engineering and construction (AEC) industry. Satellite navigation, remote sensing, mapping software, a great variety of platforms, and ever more powerful handheld computers — those are the key ingredients in today’s ecosystem of geospatial technologies. The current generation of surveying equipment has more than halved fieldwork in the past two decades while greatly improving the quality of the data collected.

    The AEC industry relies on surveyors to be “a bridge between the existing landscape and the design landscape,” said another contributor to our cover story. Unlike traditional boundary surveying, he explained, surveying for AEC requires consideration of a detailed 3D world. It also involves many more stakeholders and much greater liability.

    The tight integration of GNSS, inertial systems, lidar sensors and 360° spherical imagery into mobile mapping systems makes 3D modeling possible and traditional GNSS or optical measurement instruments obsolete. However, while inertial systems are invaluable to bridge brief gaps in the availability and reliability of GNSS signals, they are far from the panacea they are sometimes claimed to be, as Brad Parkinson reminds us in an interview with Dana Goward, also in this issue.

    Surveying for AEC requires at least centimeter accuracy. The challenges of surveying in urban settings include urban canyons that occult signals and create multipath, traffic and multiple layers of underground, ground-level and above-ground infrastructure.

    Beyond the construction phase, 3D survey data is increasingly used to create digital twins of buildings, which facilitate their operation and maintenance throughout their life cycle and help lower their carbon footprint. Once they have completed an initial survey, surveyors often set control to be used for machine control — the theme of our cover story in next month’s issue.

    In this issue we also:

    • Inaugurate a “letters to the editor” section to make more room for debate in the GNSS/PNT community on the critical issues it faces.

    • Report on a Jet Propulsion Laboratory study of the impact on the ionosphere of the enormous volcanic eruption in Tonga and the beginnings of a GNSS-based early warning system for natural hazards.

    • Continue our series of articles on GNSS constellations, with an update from Japan’s QZSS constellation.

    • Feature three studies: one on real-time simulator testing using an NMEA data stream, one on the first transmission of L1C/B signals by QZSS, and one on self-driving cars in major metropolitan areas.

    All these advances, however, are threatened when GPS is threatened. Earlier in the month, three members of our editorial advisory board comment on the recent threat to GPS satellites by the Russian government.

  • 2022 Geo Week to replace, include other conferences

    Geo Week 2022A major geospatial conference encompassing previous annual conferences is scheduled for 2022.

    The AEC Next Technology Expo & Conference, International Lidar Mapping Forum and SPAR 3D Expo & Conference will unite as one show. The new Geo Week show will also encompass partners U.S. Institute of Building Documentation (USIBD) and American Society for Photogrammetry and Remote Sensing (ASPRS).

    Geo Week, which takes place Feb. 6-8, 2022, in Denver, will bring together the best of 3D technology for the built world, geospatial applications and more. The joining of the events reflects the increased integration between the built environment, advanced airborne/terrestrial technologies and commercial 3D technologies, according to organizers.

    Geo Week will provide education, technology and resources for professionals in industries including AEC (architecture, engineering and construction), asset and facility management, disaster and emergency response, Earth observation and satellite applications, energy and utilities, infrastructure and transportation, land and natural resource management, mining and aggregates, surveying and mapping, and urban planning/smart cities.

    “We’ve witnessed the growing convergence between geospatial and the built world, and we received positive feedback from customers about holding the events together, which had been the plan for 2020 and 2021 before the pandemic forced us to cancel due to the unavoidable consequence of the worsening magnitude of the public health and safety issues caused by the COVID-19,” said Lee Corkhill, marketing director at Diversified Communications.

    “We believe the market is ready and eager for this next step of leveraging the confluence of what are becoming ubiquitous technologies for improved collaboration, increased efficiency, and better outcomes,” Corkhill continued. “Much of the conference content and technology being showcased will reflect and support this increasing integration.”
