China's surveying and mapping equipment is shifting to high precision

Introduction: New technologies, new products, and new ideas can be seen at the first National Exhibition of Surveying and Mapping Geographical Information Technology Equipment sponsored by the China Institute of Surveying and Mapping and the China Instrument and Meter Industry Association Surveying and Mapping Branch. The exhibition reveals that China's surveying and mapping equipment is shifting toward high precision, such as GPS handhelds, total stations, multi-mode multi-frequency GNSS chips, and even measuring scales.

Recently, new technologies, new products, and new ideas were seen at the first National Exhibition of Surveying and Mapping Geographic Information Technology organized by the China Surveying and Mapping Institute and the Surveying Instrument Branch of the China Instrument and Meter Industry Association.

In the exhibition hall of surveying and mapping equipment, if you do not see various surveying and mapping instruments on the booth, you may mistake it for a creative exhibition. The novelty of the exhibition booths, colorful decorations, changed the orthodox style of past surveying and mapping instruments and attracted unique audiences.

It is nothing new for a car to drive into a surveying and mapping equipment exhibition. A panoramic camera is installed on the roof of the car, and a moving laser measuring vehicle that follows and moves with the camera is representative of the most advanced new technology for surveying and mapping. The vehicle-mounted mobile measurement system developed by the team led by Liu Xianlin, an academician of the Chinese Academy of Engineering, has installed a domestic three-dimensional laser scanner, a digital photogrammetric system, and a positioning and orientation system, marking that China has entered the world's advanced ranks in this field. At Topcon's booth in Japan, the mobile measurement system was installed on a tricycle, and it may be more convenient and convenient to take pictures while riding the car. At the exhibition, the ubiquity of products at home and abroad shows that they are competing on the same stage.

The exhibition reveals that China's surveying and mapping equipment is shifting toward high precision, such as GPS handhelds, total stations, multi-mode multi-frequency GNSS chips, and even measuring scales.

Peng Zhenzhong, secretary general of the China Institute of Surveying and Mapping, stated: “China is a major producer of surveying and mapping equipment. The low-end and middle-end surveying and mapping instruments are basically at the same level as the world, but they are still catching up in the high-end areas.”

At present, the market for domestic surveying and mapping instruments has gradually been brought into line with the international market, forming the pattern in which you and I have you. With the rapid development of several major surveying and mapping instrument manufacturers, such as Guangzhou South Surveying and Mapping, Beijing Bofei, and Suzhou Yiguang, the technological R&D capability has been continuously improved, and the products have their own advantages. This will take precedence in the low-end and middle-end surveying and mapping instrument market; Imported surveying and mapping equipment manufacturers, including Leica, Switzerland, all build factories in China and seek OEM partners to seize domestic low-end surveying and mapping equipment market.

With the development of information technology, surveying and mapping instruments, which are tools for spatial information data collection and processing, are no longer simply data collectors, but are collections of surveying and mapping data, records, storage, calculations, analysis, sorting, transmission, and The picture shows the integrated data processing center. Surveying and mapping instruments have evolved from traditional optomechanical products to integrated electro-optical, electromechanical, and telecommunication products, and have evolved from single instrumentation to hardware and software systems.

According to Liang Weiming, secretary general of the Surveying Instruments Branch of the China Instrument and Meter Industry Association, the stability, reliability, and product quality of domestic surveying and mapping instrument products have yet to be further improved. In the case of limited market capacity, the company must expand its industries and transition to the geographic information industry in order to develop.
