Capable of long-duration hovering and continuous flight operations without interruption.

Powered by only two motors and designed with aerostatic lift for energy efficiency, it achieves an impressive maximum flight time of up to 50 minutes.

AERIAL SURVEY

With continuous advancements in aerial surveying technology, modern digital cameras can now clearly capture fine ground details such as manholes and drain covers. Their high-resolution imaging capabilities significantly enhance the value and accuracy of survey data.

Aerial surveying enables the rapid acquisition of high-resolution imagery and high-precision, high-density DEM data within a short time frame, minimizing environmental and temporal inconsistencies. It is widely applied in terrain change detection, topographic mapping, flood modeling, and disaster prevention. The resulting high-precision datasets deliver exceptional performance when applied to 3D Geographic Information Systems (GIS).

AERIAL DRONE PHOTOGRAMMETRY

In recent years, the rapid evolution of drone technology and the widespread availability of advanced equipment have greatly expanded the possibilities and flexibility of aerial photography. Capturing the world from above offers photographers a brand-new creative perspective and provides viewers with an entirely new way to experience the beauty of our planet through the eyes of a bird.

PHOTOGRAMMETRY

Photogrammetry is a technology that generates accurate 3D models by capturing images of an object from multiple angles and processing them through computer algorithms. From small-scale items such as matchboxes or model cars to large-scale structures and even entire cities, photogrammetry enables detailed 3D reconstruction. It is widely used in surveying, topographic analysis, and the digital preservation of cultural heritage.

3D Geographic Information System

For many years, we have been dedicated to assisting government agencies in building 2D GIS and 3D GIS systems. In addition to integrating official open data as base maps, we also help organizations consolidate and visualize their business-related datasets. Through data collection, organization, and professional GIS presentation, we transform raw information into valuable geographic insights tailored to each agency’s needs.

In terms of technical development, our 2D GIS platforms are built using government-provided APIs such as TGOS MAP API and the National Land Surveying and Mapping Center’s Map Data Cloud API. For 3D GIS, we utilize Skyline, the world’s most advanced and fluid 3D GIS technology. Responding to the growing demand for mobile accessibility, we have also expanded into cross-platform 3D GIS development, continually enhancing our systems to deliver comprehensive, innovative, and high-performance solutions. Through the passion of our skilled development team and alignment with smart land management policies, we are committed to creating high-quality, next-generation GIS platforms.

LiDAR

（Light Detection And Ranging）

Laser scanning is a breakthrough method that replaces traditional surveying with laser-based remote sensing. Using a high-speed laser rangefinder and internal scanning prism, the system accurately captures three-dimensional coordinates of every scanned point, enabling precise terrain modeling and earthwork volume analysis.

Terrestrial LiDAR (ground-based laser scanning) operates on the same principles as a total station, capable of collecting tens of thousands of measurement points per second. This not only achieves precision equal to traditional methods but also greatly enhances efficiency, producing high-resolution data suitable for digital archiving.

Mobile Mapping Services
Vehicle-Mounted System

The Mobile LiDAR System (MLS) is the first domestically developed, fully integrated long-range mobile laser scanning system designed for multiple applications — vehicle-mounted, vessel-mounted, and airborne. Equipped with high-speed laser scanners, panoramic imaging systems, and navigation-grade inertial navigation components, the MLS provides high-precision positioning and orientation performance, improving post-processing trajectory accuracy. It also maintains stability in challenging environments such as tunnels and high-speed dynamic conditions by effectively resisting satellite signal loss and environmental obstruction.

TRADITIONAL MEASUREMENT

Over the years, surveying technology has evolved to encompass many advanced methods such as LiDAR and aerial photogrammetry. However, despite the continuous advancement of modern technology, traditional surveying methods still hold an irreplaceable and essential role in the field of surveying.

Underwater Surveying Technology Applications

Underwater surveying technology provides the most accurate representation of subaquatic topography and elevation. This includes both Single Beam Echo Sounder (SBES) and Multi-Beam Echo Sounder (MBES) systems, which can be deployed in seas, rivers, harbors, coastlines, reservoirs, and ponds to determine underwater depths and generate comprehensive bathymetric maps.

Underwater Cultural Heritage Exploration

Underwater cultural heritage exploration aims to identify and analyze submerged cultural assets using advanced technologies such as Side-Scan Sonar (SSS), High-Density Bathymetric Survey (Multi-Beam Echo Sounder, MBES), Sub-Bottom Profiler (SBP), Magnetic Survey (MAG), and Underwater Photography and Videography. These methods help determine the location, appearance, and condition of underwater artifacts, forming the foundation for heritage preservation, protection, and responsible marine development.
