Problems solved by technology

The traditional method of engineering survey data collection determines that it must have the following problems: 1. The location of on-site observation points lacks real-time correlation with topographic maps, and the degree of informatization is low; 2. The collected data is often incomplete, non-standard, and non-standard , and it is inconvenient to save; 3. The original data recording, sorting and digitization workload is heavy and cumbersome; 4. Data information is basically in a decentralized and non-dynamic management state, with serious fragmentation, and even becomes a de facto "data island" , poor sharing, difficult to use later, low overall work efficiency

It is mainly manifested in the following aspects: 1. Different or incomplete data models: engineering survey requires comprehensive analysis and application of geological surveying and mapping, exploration, geophysical prospecting, testing and other information; existing collection systems and methods mostly focus on geological surveying and mapping, exploration, Few comprehensive analysis applications involving geophysical prospecting and tests are difficult to meet the basic requirements of engineering surveys

2. Spatial data conversion is difficult and cumbersome: the positioning and navigation of the field data acquisition system is based on the GIS platform and GNSS information, and the engineering survey and its upstream and downstream mostly use the CAD system for engineering design. The existing data acquisition system does not have a simple GIS and CAD format conversion function, resulting in inconvenient map format conversion, map style setting, desktop and mobile data transmission and synchronization operations between the field data collection system and engineering design system, and the workload is heavy, which is not conducive to popularization and application

3. The seamless link between different survey data cannot be realized: the data collected by the existing field data acquisition system, geophysical prospecting, indoor test and other data are not seamlessly linked with the engineering survey database, and cannot be directly used for 2D mapping and 3D geological Modeling, numerical simulation calculation, and geotechnical engineering design provide standard and standardized engineering survey information data support, reducing the secondary utilization efficiency of data
