Mapping & Geospatial

Unmanned Aerial Vehicles (UAVs) are extensively used for photogrammetry, land surveying, 3D mapping, and topographic surveying. Many industries, such as construction, oil and gas, infrastructure, archaeology, mining, forestry, and agriculture, have found CHCNAV's solutions a better alternative to traditional surveying methods. Our autonomous, long-range drones with large payload capacity, combined with scanners and cameras, effectively capture 3D data over large areas in a short period of time.

Our GNSS RTK smart antennas define precise geographic coordinates of Ground Control Points (GCPs) of the aerial survey area to enhance the positioning and accuracy of the mapping outputs dramatically. All our GNSS receivers allow GCP collection and processing of GCPs in real-time when connected to GNSS RTK Networks or in post-processing modes when combined with our CGO Geodetic Software. As a result, centimeter-level accuracy for GCPs coordinates is achieved with the ability to simply export data to your favorite drone survey processing software to create digital elevation models, 2D orthomosaic images, or 3D point clouds.

The acquisition and maintenance of reliable geo-referenced geographic data is the key factor in any mapping and geospatial project to populate your geographic information system (GIS) database. The CHCNAV GNSS Professional Controllers and Tablets associated with your preferred Android GIS applications are the perfect tools to significantly reduce the time and money spent on your projects. Your mobile workforce can collect, process and maintain spatial data efficiently, anytime, anywhere.

Mobile mapping division enables the digital world by merging and fusing technologies. Ground and airborne mobile mapping systems combine state-of-the-art, high-performance hardware, such as accurate long-range laser scanners, high-resolution HDR panoramic cameras, and advanced GNSS receivers with high-precision IMU. Our drones and mobile mapping platforms are portable and robust, allowing for efficient deployment in the field. In addition, our advanced software algorithms process massive 3D point clouds quickly and efficiently.
