- Creates centralized database ensuring consistency and accessibility for all stakeholders
Distinctive Experience on Cloud Computing Platform
ChangeDetection combines multiple remote sensing and GIS achievements on cloud computing platform, delivering superior benefits to users.
Rapid deployment with immediate field data collection
Mobile Mapping enables fast field deployment, collecting detailed geospatial data directly at the survey site without complex setup.
- The Mobile Mapping System can rapidly and accurately collect geospatial data at high detail levels as the vehicle passes through the survey area
- This is particularly beneficial in urban areas where construction and infrastructure layouts change rapidly, and traditional surveys are largely impractical or severely limited during peak traffic hours
- Multi-sensor integration on a single vehicle reduces field setup time, thereby shortening overall project timelines
- Areas that are inaccessible or hazardous can be mapped efficiently and safely using mobile platforms
High-accuracy, comprehensive and detailed data
The Mobile Mapping System ensures superior output accuracy, covering even underground and underwater structures that traditional methods struggle to reach.
- Data collected is highly accurate and comprehensive, delivering significant value to users and data owners in making decisions based on precise geospatial information
- This technology has been used to survey major road and railway projects, map urban environments, understand underground and underwater structures, and improve safety in infrastructure and power plants worldwide
- Accuracy is ensured through the combination of GNSS and wheel-mounted Distance Measuring Instrument (DMI), particularly critical in urban areas where satellite signals may be blocked by buildings and trees
- The laser scanner collects millions of 3D coordinate points, producing a Point Cloud dataset with density and detail that manual survey methods cannot achieve
Simplified operations, reduced workforce burden
The central control device centralizes the entire workflow, enabling a single operator to effectively monitor and coordinate the entire system.
- Through the central control device, all devices in the system are connected and operated from a single interface, significantly reducing the workload for operators during data collection
- The operational workflow is simpler compared to managing individual devices separately, reducing training time and the risk of errors from manual operation
- Rich data from all sensors is automatically synchronized and stored, and can be processed conveniently in the office either manually or through specialized processing software
Flexible data collection across diverse terrains
Thanks to high customizability and flexible installation, Mobile Mapping systems operate effectively across many terrain types, from urban streets to remote areas.
- Thanks to easy installation and high customizability, Mobile Mapping systems enable data collection across various terrain types, including hard-to-reach areas and complex topography
- The system can be installed on multiple platform types including cars, trains, boats, or backpacks, suited to the specific characteristics of each project and field conditions
- Vast or hazardous areas that were previously inaccessible by traditional survey methods can now be mapped safely and efficiently using mobile platforms
Significantly reduced survey time
Survey time is reduced from weeks to just days, delivering exceptional improvements in project efficiency and productivity.
- Mobile Mapping delivers a superior advantage when vast or hard-to-reach areas can be mapped effectively and quickly using mobile platforms
- Environments that previously took weeks to survey using traditional methods can now be completed in just days with Mobile Mapping technology, significantly enhancing efficiency and productivity
- Rapid data collection enables organizations and businesses to shorten overall project timelines, reducing labor costs and increasing competitiveness
- The mobile mapping system equipped with laser scanners and digital cameras can efficiently and accurately capture road signs, streets, utility grids, and vegetation in a single pass
