RIEGL
RIEGL manufactures terrestrial, airborne, and mobile LiDAR scanners that capture three-dimensional point cloud data—a core requirement for modern surveying, mapping, and industrial measurement workflows where traditional methods cannot match the speed, density, or accuracy of laser scanning.
Company Overview
RIEGL Laser Measurement Systems GmbH is an Austrian manufacturer of LiDAR (Light Detection and Ranging) systems headquartered in Horn, Austria. The company employs approximately 500 staff across its Austrian operations and international subsidiaries. Since 1978, RIEGL has focused exclusively on laser measurement technology, producing instruments for terrestrial (ground-based), airborne (helicopter and fixed-wing), and mobile (vehicle-mounted and handheld) survey platforms.
The company's market position stems from sustained investment in LiDAR hardware development rather than marketing dominance. Surveyors and engineers adopt RIEGL scanners because the instruments deliver measurable advantages: higher pulse repetition rates than competing systems, robust performance in variable ambient light, and calibrated range accuracy across extended distances. These technical properties directly affect job economics—faster scan rates reduce field time, and superior data quality reduces post-processing effort.
History and Development
Founding and Early Years (1978–1990s)
Dr. Clemens Riegl and Johann Riegl founded the company in 1978 with a focus on laser-based distance measurement. The founders recognized that electronic laser ranging offered advantages over mechanical surveying instruments, particularly for applications requiring speed or access to difficult terrain.
During the 1980s and early 1990s, RIEGL developed specialized laser measurement devices for industrial metrology and surveying. The company's early products served niche markets—precision manufacturing measurement, structural monitoring, and close-range survey work—where laser ranging outperformed conventional methods.
Terrestrial LiDAR and the 3D Scanning Era (1990s–2000s)
A significant inflection occurred in the late 1990s when RIEGL released the LMS-Z210, a terrestrial laser scanner designed for surveyors and engineers. This instrument introduced the surveying market to point cloud capture—the ability to digitally record thousands of 3D coordinates per second from a stationary position. The LMS-Z210 addressed a practical problem: detailed as-built surveys of complex structures (buildings, industrial plants, bridges) that previously required weeks of manual measurement could now be completed in days.
This product line established RIEGL's reputation within the surveying and engineering communities and initiated broader adoption of LiDAR for civil engineering, archaeology, and heritage documentation.
Airborne and Mobile Expansion (2000s–2010s)
During the 2000s, RIEGL extended its product portfolio into airborne LiDAR—scanners mounted on helicopters and fixed-wing aircraft for mapping large areas. The company's helicopter-based systems (notably the LMS-Q series) enabled rapid data acquisition across landscapes, coastlines, and forest canopies. These systems proved valuable for flood mapping, infrastructure corridor surveys, and forestry inventory.
By the 2010s, RIEGL added mobile LiDAR systems—scanners mounted on vehicles, trains, and UAV platforms—to capture data from moving platforms. This diversification meant surveyors could apply LiDAR technology to road surveys, utility corridor mapping, and UAV-based inspection work.

Technical Approach
RIEGL's engineering strategy emphasizes pulse-based LiDAR rather than solid-state approaches. Pulse-based systems emit discrete laser pulses and measure the time required for reflected light to return, enabling measurement of multiple reflections from layered surfaces (canopy penetration) and long-range accuracy. The company's scanners operate at high pulse repetition rates (up to 1.3 million pulses per second in current models), reducing survey time and improving point cloud density.
The technical specifications that matter to surveyors include:
- Range accuracy: ±25 mm to ±50 mm depending on model and distance, relevant for precision engineering surveys and as-built documentation - Maximum range: 200–800+ meters depending on system, enabling large-area capture from elevated positions - Scan speed: Point density and field productivity depend directly on pulse rate and scan pattern efficiency - Multiple returns: Ability to record multiple reflections per pulse, critical for forest surveys and penetrating dense vegetation
Market Position
RIEGL competes in the LiDAR segment against Leica Geosystems, Trimble (acquired Optech), and emerging Chinese manufacturers. The company's competitive advantages are technical rather than cost-based; RIEGL scanners typically command premium pricing, justified by performance specifications and calibration standards that matter to high-precision surveying and mapping work.
The company serves three primary customer segments:
1. Surveying and engineering firms using terrestrial scanners for as-built surveys, deformation monitoring, and facility documentation 2. National mapping agencies and geomatics contractors deploying airborne LiDAR for topographic mapping and hazard assessment 3. Specialized operators (forestry, utilities, infrastructure) using mobile and airborne platforms for asset inventory and corridor surveys
Integration with Survey Workflows
RIEGL scanners produce point cloud data that must be processed, registered, and converted into deliverables—orthophotos, digital elevation models, or as-built drawings. The company offers software tools including RiPROCESS for point cloud processing and RiCMS for reflectorless measurement and calibration.
Surveyors typically integrate RIEGL LiDAR with [Total Stations](/instruments/total-station) for geo-referencing (establishing real-world coordinates), [GNSS Receivers](/instruments/gnss-receiver) for ground control, and standard surveying workflows. Modern airborne LiDAR surveys combine RIEGL scanners with integrated GNSS and IMU (inertial measurement unit) systems to deliver geo-referenced point clouds without extensive ground control.
Research and Development
RIEGL maintains significant R&D investment focused on improving range accuracy, extending measurement distance, and reducing system size and weight. Current development priorities include increased repetition rates, improved performance in high-ambient-light conditions, and tighter integration with UAV platforms.
The company holds multiple patents related to laser pulse timing, return classification, and multi-echo processing. This patent portfolio and continuous development effort create barriers to entry and explain the company's sustained premium pricing.
Sustainability and Industry Trends
LiDAR adoption has accelerated across surveying due to regulatory mandates for detailed topographic data, climate adaptation initiatives (flood mapping), and digital twin projects in infrastructure. RIEGL benefits from these trends as a specialized supplier.
The industry trend toward higher-resolution point clouds (denser point spacing) and multi-sensor systems (combining LiDAR with hyperspectral or thermal imaging) drives demand for faster, more capable scanners—RIEGL's technical focus area.
Conclusion
RIEGL's position in surveying markets reflects consistent engineering focus on LiDAR performance rather than diversification into adjacent sectors. For surveyors evaluating [LiDAR systems](/instruments/lidar) and point cloud capture methods, RIEGL represents the technical standard against which competing systems are often benchmarked. The company's product portfolio now spans the complete range of survey platforms—ground, air, and mobile—making it relevant to diverse surveying disciplines.
